1. Design and mode of operation

HALOTRONIC®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®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.

Because HALOTRONIC®transformers have such a low power loss, they

generate much less heat than conventional transformers.

In partial load operation, HALOTRONIC®transformers do not produce

overvoltages so even in this mode of operation there is no reduction in the

life of the lamp.

HALOTRONIC®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):

- with long casing (L)

- with low-profile casing (LF)

- for particularly small spaces (HTM)

• For installation in luminaires:

Units in different shapes and wattage levels, with and without casings.

- square with casing (S)

- round with casing (C)

- round with casing, open (CO)

- board model (B)

All stand alone units can also be installed in luminaires.

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®may be

damaged beyond repair.

Every HALOTRONIC®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).

3. Performance

3.1 Electrical and photometric

data as a function of mains

voltage and lamp wattage

HALOTRONIC®is designed for a 230V supply or a 230 - 240 V supply

depending on the model. Lamps connected to HALOTRONIC®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®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.

Table 1

3.4

Permissible temperature range

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®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).

HALOTRONIC®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®outside a luminaire, make sure that it is not

placed too near a heat source (such as the lamp itself), otherwise overheating

may occur.

When installing HALOTRONIC®inside a luminaire, the measuring point

temperature on the casing (tc) 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.

1) Short-circuit the potentiometer connections if phase dimmers with control on the trailing edge

are used.

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 kΩpotentiometer.

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 kΩlin, 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 kΩlin, Type PC 16 hl P6 with plastic spindle, available from Piher

International GmbH, Orchideenstr. 6, D-90542 Eckental

There are also various 750 W dimmer modules available for dimming

HALOTRONIC®(see page 8): HT 1-10 DIM, HT TOUCH DIM and HT BOOST

DIM for electronic transformers with no resistive load.

HALOTRONIC®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.

3.5 Minimum load

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 20 W for 20 VA transformers

A minimum load of 35 W for 50 VA transformers

A minimum load of 35 W for 60 VA transformers

A minimum load of 75 W for 105 VA transformers

A minimum load of 150 W for 210 VA 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.

HALOTRONIC®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)

3.6.1 Installation instructions

for dimmer modules

3.7 Short-circuit protection

HALOTRONIC®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.

HALOTRONIC®transformers meet the requirements relating to safety

transformers for safety extra-low voltage2).

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).

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.

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.

HALOTRONIC®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.

HALOTRONIC®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®trans-

formers cannot be connected in parallel on the secondary side because they

would be overloaded.

Series connection to operate 24 V lamps is not permitted.

The following table indicates the maximum number of HALOTRONIC®trans-

formers that can be connected to an automatic cut-out.

3.15 Start-up current The table below shows the peak values for the maximum start-up current Îmax.

(time: 10 ms, half sine wave) for a cold lamp.

The failure rate of electronic components obviously depends on their

specifications and construction quality but the temperature at which they

operate also plays quite a significant role. HALOTRONIC®units are designed

so that at the maximum permissible device temperature (tcmax.) 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.

4.2 Main advantages of using

HALOTRONIC®:

Installation in false ceilings

5. Notes on separate installation

and installation in luminaires

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 non-

parallel 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 short-

circuit protection circuit in the transformer may fail to respond or, in extreme

cases, the unit may fail altogether.

The following cables are recommended for the units designed for separate

installation:

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 un-

protected 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.

• One and the same screwdriver can be used to lever off the blanking caps,

connect the wires and adjust the strain relief

• Strain relief possible on the primary side for two NYM 3 x 1.5 mm2cables

• Three pairs of terminals on the secondary side for the parallel connection of

three luminaires

• Sufficient cable space in front of the screw terminals

LF models:

• Extremely low-profile design

• Two pairs of terminals on the primary side for mains looping through

• Strain relief possible on the primary side for two NYM 3 x 1.5 mm2cables

• Two pairs of terminals on the secondary side for the parallel connection of

Table 3: Minimum depth of the suspended ceiling for installing HALOTRONIC®

transformers (for a ≤13 mm).

5.5 Heat dissipation The units generate little heat, but this heat still has to be dissipated. 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®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).

If HALOTRONIC®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®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.

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.
