Design and mode of operation HALOTRONIC(R) transformers are electronic transformers which replace conventional transformers for operating 12 V tungsten-halogen lamps. They have only 60 % of the volume, 20 % of the weight and 30 % of the power loss of conventional transformers. The diagram below shows the way in which the HALOTRONIC(R) transformer works. The mains voltage is rectified, converted into a high-frequency voltage in the chopper, converted back into an ac voltage and fed to an output converter which converts it into a 12 V ac-voltage. A filter ensures that radio interference standards are met and helps make the unit immune to interference. Block diagram 230 V dc Filter Rectifier HF chopper DC/AC Converter Lamp 12 V ac Fig. 1 Because HALOTRONIC(R) transformers have such a low power loss, they generate much less heat than conventional transformers. In partial load operation, HALOTRONIC(R) transformers do not produce overvoltages so even in this mode of operation there is no reduction in the life of the lamp. 2. Range and technical data HALOTRONIC(R) is available in different versions, with and without casings, for wattages between 60 W and 210 W. * For separate installation (stand alone units with casings and strain relief): -

Performance 3.1 Electrical and photometric data as a function of mains voltage and lamp wattage HALOTRONIC(R) is designed for a 230V supply or a 230 - 240 V supply depending on the model. Lamps connected to HALOTRONIC(R) react to overvoltages and undervoltages in the same way as when they are connected to normal transformers. In other words, overvoltages lead to a sharp reduction in lamp life, and undervoltages lead to a drop in luminous efficacy. The diagram on the left below shows the situation for a conventional 100 VA transformer not suitable for partial load operation. When operating a 20 W lamp for example, the high secondary voltage (> 13.5 V) causes lamp life to be sharply reduced. This increase in the operating voltage of the lamp of more than 10% leads to a reduction of about 60% in the life of the lamp. HALOTRONIC(R) on the other hand operates lamps reliably over the entire partial load range. One advantage of partial load operation is that the failure of one lamp in a multi-lamp luminaire will not lead to the premature failure of the remaining lamps. 15,0 400 140 14,0 130 300 13,5 120 12,5 11,5 11,0 110 r colour Most simila 100 temperature 100 e 90 105 y nt ficac Curre ef us o ion n pt mi Lu um s on rc we o P 80 60 flu x 10,5 Lif 150 e Output voltage V 12,0 200 Lif Relative operating values in % 13,0 60 Lamp wattage W 80 100 120 no 40 mi 20 80 40 Lu 0 us 10,0 25 105 110 70 90 95 100 Conventional transformer not suitable for partial loads HT 105/230/12 L Operating voltage as a %age of rated voltage Fig. 2 3.2 Permissible mains voltage range For a 230 (240) V ac supply, the nominal supply voltage is 230 Vrms (240 Vrms ). Overvoltages of up to 6% are permissible. If the voltage is 6 % higher correct operation cannot be guaranteed and HALOTRONIC(R) may be damaged beyond repair. Every HALOTRONIC(R) transformer is protected (to EN 61047, IEC 61047 or VDE 0712T24) against transient mains overvoltages (these occur, for example, when inductive loads such as fluorescent lamps operated with conventional control gear are switched off). 9 3.3 Operation on dc supplies The models indicated by the symbol or 0 Hz in the technical data can be operated on a dc supply and are therefore suitable for use in emergency lighting to VDE 0108. Lamps connected to HALOTRONIC(R) transformers emit the same luminous flux whether an ac or dc supply is used. The permissible dc voltage range is 154 V to 244 V 1). 3.4 Permissible temperature range HALOTRONIC(R) transformers operate reliably within the temperature range specified for each particular model (see technical data). Excessive temperatures will cause electronic components to fail prematurely and the transformer will not be able to achieve its specified life expectancy.

When installing HALOTRONIC(R) inside a luminaire, the measuring point temperature on the casing (t c ) is the crucial factor. If units without a casing are installed in a luminaire, temperature tc must be measured on certain electronic components. The limit temperatures on the components specified for the particular model must not be exceeded (see Figs. 4 and 5). 1) Below 207 V the safety protection in case of overload (e.g. additional lamp load) is not provided anymore. 10 tc2 HT 105/230/12 C HT 105/230/12 CO t c1 85 C t c2 85 C 80.6 29.2 14.6 29.2 66.6 45 O 6.2 14.6 35.5 O 3.2 tc2 tc1 10 10 4 66.6 O 3.7 Fig. 3 27 53 HT 65/230 - 240/12 SB t c 110 C tc 53 Fig. 4 HTM 70/230-240 B HTM 105/230-240 B t c 80 C 30 41 tc 84 84 Fig. 5 11 3.5 Minimum load HALOTRONIC(R) transformers must be operated with a lamp wattage which corresponds at least to the minimum load (see technical data). If this minimum load is not reached, harmonics and/or radio interference values may exceed the permissible thresholds and output voltage will fall considerably (see Fig. 6). The unit is unlikely to be damaged, however. Fig. 6 shows the output voltage curve as a function of lamp load for HT 105/230/12L.

If potentiometers are used for dimming do not connect phase dimmers with control on the trailing edge in series. HT 105 C and CO can also be dimmed with a 50 k potentiometer. The terminals for connecting the potentiometer are at mains potential. For safety reasons, you should only use potentiometers with insulated spindles. We recommend the following: * Preh, rated at 50 k lin, Preostat 16 Iso Mono, Type No. 63610-009, available from Preh Werke GmbH & Co. KG, An der Stadthalle, D-97616 Bad Neustadt an der Saale * Piher, rated at 50 k lin, Type PC 16 hl P6 with plastic spindle, available from Piher International GmbH, Orchideenstr. 6, D-90542 Eckental Table 2 There are also various 750 W dimmer modules available for dimming HALOTRONIC(R) (see page 8): HT 1-10 DIM, HT TOUCH DIM and HT BOOST DIM for electronic transformers with no resistive load. 12 3.6.1 Installation instructions for dimmer modules Suitable for installation in false ceilings with minimum ceiling openings (approx. 60 mm diameter) or for surface mounting. The connected load of the units must be at least 60 W and must not exceed 750 W. The specified minimum load of the transformers must be achieved or exceeded. We recommend the following: A minimum load of A minimum load of A minimum load of A minimum load of A minimum load of 20 W 35 W 35 W 75 W 150 W for for for for for 20 VA 50 VA 60 VA 105 VA 210 VA transformers transformers transformers transformers transformers Flickering may occur if the load is less than these minimum values. The maximum load capacity of trailing-edge phase dimmers and that of an additional power unit is 750 W. Output power can be increased several times by connecting units together. With touch-sensitive dimmers, this is done by connecting appropriate additional power units (HT BOOST DIM). If the 1-10 V interface is used for dimming (HT 1-10 DIM), expansion of the power handling capacity is achieved by connecting these units in parallel on the primary side. Each additional unit expands the power handling capacity by 750 W. HT 1 - 10 DIM => control via the 1 - 10 V interface Controls: 1) Potentiometer 470 kOhm, preferably log. 2) Manual control unit (for installation in flush-type box), e.g. Siemens 5 LZ 9020-4 C, Busch-Jaeger Electronic Potentiometer 2112 U-101, Philips LPS 3) Manual control unit or potentiometer with series-connected amplifier module, e.g. Siemens signal amplifier 5 LZ 9021-4A, Siemens light sensor 5 LZ 9020-4D HT TOUCH DIM => control via one or more switches connected in parallel. Switching and dimming are controlled by pressing the switch: Short press: ON/OFF; the last value is stored Longer press: Dimming HT BOOST DIM => Additional power unit for HT TOUCH DIM Control via a control output on HT TOUCH DIM; by connecting additional power units in parallel it is possible to increase the wattage handled and therefore control complex lighting systems from one or more switches. Each unit has an electronic cut-out which disconnects the output or limits the power in the event of a short-circuit, overload or overtemperature. Depending on the type and duration of the fault, it may be necessary to reconnect the mains voltage. 3.7 Short-circuit protection HALOTRONIC(R) transformers protect themselves against the effects of a short-circuit on the secondary side. All the units have electronic cut-outs. These ensure that the units will not be destroyed by a short-circuit 1). The units will be fully operational again once the cause of the short-circuit has been eliminated. 1) Applies only if supplied with 50 Hz ac voltage (the HT ... L family is suitable for dc or ac voltage) 13 3.8 Overload/overtemperature protection HALOTRONIC(R) units are equipped with electronic overload protection. Even if the overload persists, there will be no damage to the unit. The output power is either reduced or automatically disconnected. For a 2 m long cable, the overload protection circuit will be triggered at around twice the maximum permissible load1). If external heat sources cause the temperature at the unit to exceed the specified maximum, they will automatically reduce their output to protect themselves1). The user will notice a drop in the luminous flux of the lamps supplied by the transformers. 3.9 Safety, electrical isolation HALOTRONIC(R) transformers meet the requirements relating to safety transformers for safety extra-low voltage 2). The dielectric strength (electrical isolation) between the primary and secondary sides is tested on each unit at a voltage of 4 kV. The transformers are also constructed and approved in accordance with EN 61046 (IEC 61046, VDE 0712 T24) (Electronic Converters, Safety). 3.10 Radio interference suppression For stand alone units (separate converters, with strain relief): The units comply with the limit values for radio interference voltage in accordance with EN 55015 IEC. The length of 12 V cables must be less than 2 m to comply with radio interference requirements (this means that luminaires can be installed within a radius of 2 m diameter around the electronic transformer). For units installed in luminaires (all types): A high-quality internal filter ensures that the unit complies with the radio interference values specified in EN 55015. No additional radio interference measures are required if the unit is installed in luminaires of protection class II. If the units are installed in protection class I luminaires, radio interference increases as a result of the higher earth capacitances. It may then be necessary to include an additional mains filter with an earth connection. In either case, the luminaire manufacturer is responsible for checking the radio interference levels of the complete luminaire since these levels are affected by the installation of transformer units. The locations of the primary and secondary lines in particular can have a significant effect (see also 5.3). The HT 105/230/12 C and HT 105/230/12 CO are special models in that the radio interference suppression filters in these units are designed so that the units can be used without any problems in both protection class I and protection class II luminaires. 1) Applies only if supplied with 50 Hz ac voltage (the HT ... L family is suitable for dc or ac voltage) 2) SELV or SELV equivalent to EN 61046 14 3.11 Mains harmonics HALOTRONIC(R) transformers comply with the approval requirements for mains harmonics specified in EN 61000-3-2 (IEC 61000-3-2; VDE 0838 T2). % 30 25 Mains harmonic content 20 15 10 5 0 3 Harmonics 5 7 HALOTRONIC(R) 9 11 13 Limit values to EN 61000-3-2 Fig. 7 3.12 Immunity to interference The units comply with the immunity requirements laid down in EN 61547 (IEC 61547, VDE 0875 T15-2). This means that they are protected against the external influences of high-frequency fields, discharge of static electricity and transient overvoltages in the mains supply, as defined in EN 61547. 3.13 Noise emission HALOTRONIC(R) units are almost silent in operation. Under worst case conditions (mounted on a wooden board), HT 70 L and HT 105 L emit a sound power level LWA of less than 10 dB (A) in undimmed mode. Even in dimmed mode with a phase dimmer in the least favourable dimmer setting, the sound power level is less than 20 dB (A) *). This corresponds to a sound pressure level of 17 dB (A) in a typical living room. By comparison, acceptable sound pressure levels are as follows: * for a quiet living room: 35 dB (A) * for an office: 35 dB (A) *) Test set-up: dimmer located outside the room, measurements taken on one unit, operation at maximum rated load. 3.14 Parallel/series connections HALOTRONIC(R) units can be connected in parallel on the primary side. In the case of the HT ... L and HT ... LF models, the second pair of terminals can be used on the primary side. In professional applications, several units can therefore be connected to a single dimmer. In contrast to conventional transformers, however, HALOTRONIC(R) transformers cannot be connected in parallel on the secondary side because they would be overloaded. Series connection to operate 24 V lamps is not permitted. permitted Dimmer HALOTRONIC(R) not permitted Dimmer HALOTRONIC(R) HALOTRONIC(R) HALOTRONIC(R) HALOTRONIC(R) Fig. 8 15 3.15 Start-up current The table below shows the peak values for the maximum start-up current I (time: 10 ms, half sine wave) for a cold lamp. max.

HALOTRONIC(R) units are designed so that at the maximum permissible device temperature (t c max.) a failure rate of fewer than 2 per thousand per 1000 hours of operation can be expected. This corresponds to a life of 50,000 hours at a percentage component failure of less than 10% (HTM: 30,000 hours at a percentage component failure of less than 10%). By lowering the operating temperature by 10 degrees it is possible to halve the failure rate. 16 4. Benefits for users 4.1 Luminaires for HALOTRONIC(R) Fixed spotlights Power rail spotlights Desk lights Surface-mounted ceiling luminaires Areas of application: Installation in false ceilings 4.2 Main advantages of using HALOTRONIC(R): * Foyers/reception areas * Passages/corridors * Sales areas and exhibition rooms * Individual offices/conference rooms * Accent lighting * Decorative lighting Comfort: * Just like the cased HALOTRONIC(R) units, the circuit boards have much smaller dimensions and much lower weights than conventional units * Silent dimming; with different dimmers depending on the type (see Table 2 on page 12). Economy: * Protective operation throughout the entire partial load range * 2/3 less heat generated by the luminaire * Ready for installation with no additional fusing required * Lower power consumption than a conventional transformer Safety: * The units offer an electronically reversible cut-out to protect against short circuits, overloads and overtemperature * All units are ENEC and/or VDE tested * Suitable without any additional measures for luminaires of protection class II and III (for L models) and for luminaires with b and bb symbols or with and symbols * The units comply with European standards for safety, operation and EMC * Direct current operation for emergency lighting systems to VDE 0108 possible with HT...L-types (see 3.3) 17 5. Notes on separate installation and installation in luminaires 5.1 Maximum 12 V cable length The length of 12 V cables must be less than 2 m to comply with radio interference limit values. This means that luminaires can be installed within a radius of 2 m around the electronic transformer. There is no advantage in terms of radio interference suppression in using shielded cables for the secondary line since both secondary poles carry high frequency, which makes shielding impossible. Note also that long secondary cable lengths (more than 2 m) and/or nonparallel or twisted wires (large loops) produce a large inductance for the electronic transformer. Because of the associated loss of voltage on the cables, this leads to a low lamp voltage. The lamps may flicker, the shortcircuit protection circuit in the transformer may fail to respond or, in extreme cases, the unit may fail altogether. 5.2 Recommended cables The following cables are recommended for the units designed for separate installation: HT 70 L HT 105 L HT 150 L HT 210 L HT 120 LF Mains cable 1) H03VV/F 2 x 0.50 mm2; H03VV/F 2 x 0.75 mm2; H05VV/F 2 x 0.75 mm2; NYM 3 x 1.5 mm2 NYM H03VV/F H03VVH2/F H05VV/F 3 x1.5 mm2; 2 x 0.75 mm2; 2 x 0.75 mm2; 2 x 0.75 mm2 NYM 3 x1.5 mm2 Secondary cable 1) H03VV/F 2 x 0.75 mm2; H05VV/F 2 x 0.75 mm2; H05VV/F 2 x 1.00 mm2; H05VV/F 2 x 1.50 mm2; NYM H03VV/F H03VVH2/F H05VV/F 3 x 1.5 mm2; 2 x 0.75 mm2; 2 x 0.75 mm2; 2 x 0.75 mm2 NYM 3 x1.5 mm2 Length a 20 mm 15 mm 15 mm Length b 10 mm 7 mm 8 mm 1) HTM 70 HTM 105 to DIN 57281 Stripping lengths a b 18 5.3 Cable routing To ensure good radio interference suppression and maximum safety and reliability, the following rules for cable routing should be observed: 1. Cables between the transformer and the lamp (HF cables) should be kept as short as possible (to reduce electromagnetic interference). 2. Mains and lamp cables should never be routed in parallel. Keep HF cables and mains cables as far away from one another as possible (e.g. 5 to 10 cm). This avoids mutual interference between mains and lamp cables. 3. Lay HF cables away from earthed metal surfaces (if possible several cm away) to reduce capacitative interference. 4. If two long single HF cables are unavoidable they must be twisted together. 5. Keep mains cables in the luminaire as short as possible to reduced interference. 6. Do not lay mains cables too close to the transformer (this applies in particular to through-wiring). 7. Avoid crossing mains cables and lamp cables; if this is not possible, they should cross at right angles (to reduce HF interference on the mains cable). Cable penetrations through metal components should never be left unprotected and should be fitted with additional insulation (sleeve, grommet, edge protector, etc.). Electronic transformers can be installed in a wide variety of places, including suspended ceilings, furniture, luminaires and tube systems. The transformers may be mounted on wood since the units comply with the 5.4 Installation correct wiring incorrect wiring HALOTRONIC(R) HALOTRONIC (R) HALOTRONIC(R) requirements for M M labelling according to VDE 0710 and VDE 0100 Part 559. If HALOTRONIC is to be dimmed it should be installed away from resonating surfaces so that any dimming noise is not magnified by vibrations.

To avoid overheating, make sure that the electronic transformer is not installed too close to a heat source (a lamp, for example). If the units are to be installed in luminaires, take suitable steps to ensure there is good heat transfer between the HALOTRONIC(R) unit and the luminaire casing. Temperature tc at the test point must be measured to ensure that it does not exceed its maximum permissible value. Low unit temperatures prolong the life of the unit (see also 3.17). 5.6 Integration in luminaires If HALOTRONIC(R) transformers, particularly the uncased units, are to be installed in luminaires, the luminaire manufacturer is responsible for complying with the necessary clearances and leakage paths and for providing adequate protection against electrical shock, as defined in EN 60598. Since all HALOTRONIC(R) models are protection class II devices, radio interference values must be checked if the units are installed in metallic protection class I luminaires. If necessary, external filters must be fitted to bring these values within the permitted range. 5.7 Instruments for secondary voltage measurement An instrument for secondary voltage measurement must allow measurement of the true rms value and have a bandwidth of at least 500 kHz (-3 dB). Any other instrument will give incorrect measurements. 21 6.
