Features include high efficiency, high reliability, low output voltage noise and excellent dynamic response to load/line changes. LK models can be powered by DC or AC with a wide-input frequency range (without PFC). The converter inputs are protected against surges and transients. Input over- and undervoltage lockout circuitry disables the outputs, if the input voltage is outside of the specified range. Certain types include an inrush current limiter preventing circuit breakers and fuses from tripping at switchon. Full input-to-output, input-to-case, output-to-case, and output to output isolation is provided. The converters are designed, built, and safety-approved to the international safety standards IEC/EN 60950-1. They are particulary suitable for railway applications and comply with EN 50155 and EN 50121-2-3. The case design allows operation at nominal load up to 71 C in a free-air ambient temperature. If forced cooling is provided, the ambient temperature may exceed 71 C, but the case temperature must remain below 95 C under all conditions. A temperature sensor generates an inhibit signal, which disables the outputs when the case temperature TC exceeds the limit. The outputs are automatically re-enabled, when the temperature drops below the limit. All outputs are open- and short-circuit proof, and are protected against overvoltages by means of built-in suppressor diodes. The output can be inhibited by a logic signal applied to pin 18 (i). The inhibit function is not used, pin 18 must be connected with pin 14 to enable the outputs. Various options are available to adapt the converters to individual applications. LED indicators display the status of the converter and allow for visual monitoring of the system at any time. Important: For applications requiring compliance with IEC/EN 61000-3-2 (harmonic distortion), please use our LK4000 or LK5000 Series with incorporated power factor correction (PFC).

BCD20002-G Rev AB, 12-Jul-2010 Page 3 of 31 www.power-one.com K Series Data Sheet 150 Watt DC-DC and AC-DC Converters (R) Functional Description The input voltage is fed via an input fuse, an input filter, a bridge rectifier (LK models only), and an inrush current limiter to the input capacitor. This capacitor sources a singletransistor forward converter with a special clamping circuit and provides the power during the hold-up time. Each output is powered by a separate secondary winding of the main transformer. The resultant voltages are rectified and their ripple smoothed by a power choke and an output filter. The control logic senses the main output voltage Vo1 and generates, with respect to the maximum admissible output currents, the control signal for the switching transistor of the forward converter. The second output of double-output models is tracking to the main output, but has its own current limiting circuit. If the main output voltage drops due to current limitation, the second output voltage will fall as well and vice versa. Standard models with a single 5.1 V output have a synchronous rectifier to provide good efficiency. 03057a 18 i 20 D/V 4 4 3 12 S+ 4 10 3 4 Vo+ Vo- 14 S- CY - Fig. 1 Block diagram of single-output converters 2 8 CY 30 Vi- 32 24 1 6 Output filter CY 22 T Control circuit Bridge rectifier 4 Ci + Fuse 1 Input filter 2 P 16 R CY Forward converter (approx. 120 kHz) 4 N Opt.

Subsequent switch-on/off cycles increase the inrush current peak value. For 1 s max. Nominal frequency range is 50 - 60 Hz. Operating frequency range is 47 - 440 Hz (440 Hz for 115 V mains). For frequencies 63 Hz, refer to Installation Instructions. BCD20002-G Rev AB, 12-Jul-2010 Page 5 of 31 www.power-one.com K Series Data Sheet 150 Watt DC-DC and AC-DC Converters (R) Input Transient Protection Inrush Current Limitation A suppressor diode or a VDR (depending upon the input voltage range) together with the input fuse and a symmetrical input filter form an effective protection against high input transient voltages which, typically occur in most installations, but especially in battery-driven mobile applications. The CK, DK, EK, and LK models incorporate an NTC resistor in the input circuitry, which at initial turn-on reduces the peak inrush current value by a factor of 5 - 10, such protecting connectors and switching devices from damage. Subsequent switch-on cycles within short periods will cause an increase of the peak inrush current value due to the warming-up of the NTC resistor. See also Option E. Standard nominal battery voltages are: 12, 24, 36, 48, 60, 72, 110, and 220 V. Railway batteries are specified with a tolerance of -30% to +25%, with short excursions up to 40%. In certain applications, additional surges according to RIA 12 are specified. The power supply must not switch off during these surges, and since their energy can practically not be absorbed, an extremely wide input range is required. The EK input range for 110 V batteries has been designed and tested to meet this requirement. The inrush current peak value (initial switch-on cycle) can be determined by following calculation; see also fig. 3: Vi source Iinr p = ---------------- (Rs ext + Ri + RNTC) 05109a Rs ext Input Fuse + A fuse mounted inside the converter protects against severe defects. This fuse may not fully protect the converter, when the input voltage exceeds 200 VDC. In applications, where the converters operate at source voltages above 200 VDC, an external fuse or a circuit breaker at system level should be installed.

BCD20002-G Rev AB, 12-Jul-2010 The converters (except LK models) are not protected against reverse polarity at the input to avoid unwanted power losses. In general, only the input fuse will trip.

LK models only (twice the input frequency) www.power-one.com K Series Data Sheet 150 Watt DC-DC and AC-DC Converters (R) Thermal Considerations If a converter is located in free, quasi-stationary air (convection cooling) at the indicated maximum ambient temperature TA max (see table Temperature specifications) and is operated at its nominal input voltage and output power, the temperature measured at the Measuring point of case temperature TC (see Mechanical Data) will approach the indicated value TC max after the warm-up phase. However, the relationship between TA and TC depends heavily upon the conditions of operation and integration into a system. The thermal conditions are influenced by input voltage, output current, airflow, and temperature of surrounding components and surfaces. TA max is therefore, contrary to TC max, an indicative value only. Caution: The installer must ensure that under all operating conditions TC remains within the limits stated in the table Temperature specifications. Notes: Sufficient forced cooling or an additional heat sink allows TA to be higher than 71 C (e.g., 85 C), as long as TC max is not exceeded. Details are specified in fig. 8. applied overvoltages. Overload at any of the outputs will cause a shut-down of all outputs. A red LED indicates the overload condition. Note: Vo BR is specified in Electrical Output Data. If this voltage is exceeded, the suppressor diode generates losses and may become a short circuit. Parallel and Series Connection Single- or double-output models with equal output voltage can be connected in parallel using option T (current sharing). If the T pins are interconnected, all converters share the output current equally. Single-output models and/or main and second outputs of double-output models can be connected in series with any other (similar) output. Notes: - Parallel connection of double-output models should always include both, main and second output to maintain good regulation. - Not more than 5 converters should be connected in parallel. - Series connection of second outputs without involving their main outputs should be avoided, as regulation may be poor. 1.0 - Models with a rated output voltage above 36 V need additional measures to comply with the requirements of SELV (Safe Extra Low Voltage). 05089a Io /Io nom 0.8 Forced cooling Convection cooling - The maximum output current is limited by the output with the lowest current limitation, if several outputs are connected in series. 0.6 TC max 0.4 Output Voltage Regulation The following figures apply to single-output or double-output models with parallel-connected outputs. 0.2 0 TA min 50 60 70 80 90 100 TA [C] Vo/Vo nom 0.98 Fig. 8 Output current derating versus temperature for -7 and -9 models. Thermal Protection 0.5 A temperature sensor generates an internal inhibit signal, which disables the outputs, when the case temperature exceeds TC max. The outputs automatically recover, when the temperature drops below this limit. Continuous operation under simultaneous extreme worstcase conditions of the following three parameters should be avoided: Minimum input voltage, maximum output power, and maximum temperature. Output Protection Each output is protected against overvoltages, which could occur due to a failure of the internal control circuit. Voltage suppressor diodes (which under worst case condition may become a short circuit) provide the required protection.

In systems with several converters, this feature can be used to control the activation sequence of the converters. If the inhibit function is not required, connect the inhibit pin 18 with pin 14!

Incorrectly connected sense lines may activate the overvoltage protection resulting in a permanent short-circuit of the output. This feature allows for compensation of voltage drops across the connector contacts and if necessary, across the load lines. We recommend connecting the sense lines directly at the female connector. To ensure correct operation, both sense lines (S+, S-) should be connected to their respective power outputs (Vo+ and Vo-), and the voltage difference between any sense line and its respective power output (as measured on the connector) should not exceed the following values: Table 7: Maximum voltage compensation allowed using sense lines Vinh S-/Vo1- 14 Vi- Output voltage Fig. 14 Definition of Vinh and Iinh.

The LK4000/5000 models are intended to replace the LK1000 and LK2000 converters in order to comply with IEC/EN 61000-3-2. LK1000 is replaced by LK4003 with option K. Connector Pin Allocation The connector pin allocation table defines the electrical potentials and the physical pin positions on the H15 or H15S4 connector. The protective earth is connected by a leading pin (no. 24), ensuring that it makes contact with the female connector first. 10010a Fixtures for connector retention clips V (see Accessories) The converters are components, intended exclusively for inclusion within other equipment by an industrial assembly operation or by professional installers. Installation must strictly follow the national safety regulations in compliance with the enclosure, mounting, creepage, clearance, casualty, markings, and segregation requirements of the end-use application. Connection to the system shall be made via the female connector H15 (standard) or H15S4; see Accessories. Other installation methods may not meet the safety requirements. 32 4 Pin no. 24 ( ) is connected with the case. For safety reasons it is essential to connect this pin reliably to protective earth. Type H15 The input pins 30/32 (Vi- or L ) are connected via a built-in fuse, which is designed to protect in the case of a converter failure. An additional external fuse, suitable for the application, might be necessary in the wiring to the other input 26 /28 (Vi+ or N ) or even to pins 30/32, particularly if: Fixtures for connector retention clips V (see Accessories) 30/32 * Local requirements demand an individual fuse in each source line 4/6 * Phase and neutral of the AC mains are not defined or cannot be assigned to the corresponding terminals.

BCD20002-G Rev AB, 12-Jul-2010 Page 20 of 31 www.power-one.com K Series Data Sheet 150 Watt DC-DC and AC-DC Converters (R) Notes: Cleaning Agents - If the inhibit function is not used, pin no. 18 (i) should be connected with pin no. 14 to enable the output(s). In order to avoid possible damage, any penetration of cleaning fluids has to be prevented, since the power supplies are not hermetically sealed. - Do not open the converters, or warranty will be invalidated. - Due to high current values, the converters provide two internally parallel contacts for certain paths (pins 4/6, 8/10, 26/ 28 and 30/32). It is recommended to connect both female connector pins of each path in order to keep the voltage drop low and avoid excessive connector currents. - If the second output of double-output models is not used, connect it parallel with the main output. Make sure that there is sufficient airflow available for convection cooling and verifiy it by measuring the case temperature TC, when the converter is installed and operated in the end-use application; see Thermal Considerations. Protection Degree Condition: Female connector fitted to the converter. * IP 30: All models except those with option P, and except those with option D or V including a potentiometer. * IP 20: All models fitted with option P, or with option D or V with potentiometer. Railway Application Ensure that a converter failure (e.g., an internal short-circuit) does not result in a hazardous condition. The converters have been designed by observing the railway standards EN 50155, EN 50121-3-2, and EN 50121-4. All boards are coated with a protective lacquer. Standards and Approvals Isolation and Protective Earth The converters are safety-approved to UL 60950-1, CSA 60950-1, IEC 60950-1, and EN 60950-1. The electric strength test is performed in the factory as routine test according to EN 50116 and IEC/EN 60950 and should not be repeated in the field. Power-One will not honor any warranty claims resulting from electric strength field tests. The resistance of the earth connection to the case (<0.1 ) is tested as well. The converters correspond to Class I equipment and have been evaluated for: * Building-in * Basic insulation between input and case based on 250 VAC, and double or reinforced insulation between input and output(s) * Functional insulation between outputs * Overvoltage category II Leakage Currents Leakage currents flow due to internal leakage capacitances and Y-capacitors. The current values are proportional to the supply voltage and are specified in the table below. * Pollution degree 2 environment LK Models Operated at Greater than 63 Hz * Max. altitude: 2000 m Above 63 Hz, the earth leakage current may exceed 3.5 mA, the maximum value allowed in IEC 60950. Frequencies 350 Hz are only permitted with Vi 200 VAC. * The converters fulfill the requirements of a fire enclosure. The converters are subject to manufacturing surveillance in accordance with the above mentioned standards and ISO 9001:2000. A CB-scheme is available. The built-in Y-caps are approved for 100 Hz. Safety approvals and CB scheme cover only 50 - 60 Hz.

Option D6 is necessary to disable the converter at low input voltage, such avoiding an excessive input current. Connect output D (pin 20) with inhibit (pin 18). Option D6 should be adjustded with the potentiometer to a threshold of 36 - 40.5 V for 48 V batteries and to 44 - 50 V for 60 V batteries. Refer also to the description of option D. Converter Input Filter LK models depends on model, but the tables below show the higher of both peaks. Note: Subsequent switch-on cycles at start-up are limited to max. 10 cycles during the first 20 seconds (cold converter) and then to max. 1 cycle every 8 s. RI LK models powered by 230 VAC/ 50 Hz exhibit an inrush current as per the fig. below, when switched on at the peak of Vi. In this case, the inrush current I inr p is 21.7 A and its duration tinr is 5 ms. This is the worst case.

The current I D through the JFET should not exceed 2.5 mA. The JFET is protected by a 0.5 W Zener diode of 8.2 V against external overvoltages. NPN output (D5 - DD): Pin D is internally connected via the collector-emitter path of a NPN transistor to the negative potential of output 1. VD < 0.4 V If Vi is monitored, the internal input voltage after the input filter is measured. Consequently this voltage differs from the voltage at the connector pins by the voltage drop V ti across the input filter. The threshold levels of the D0 and D9 options are factory adjusted at nominal output current Io nom and TA = 25 C. The value of V ti depends upon input voltage range (CK, DK, ..), threshold level Vt, temperature, and input current.

This option defines an undervoltage monitoring circuit for the input or for the input and main output voltage ( 5.1 V) similar to option D and generates an ACFAIL signal (V signal), which conforms to the VME standard. The low state level of the ACFAIL signal is specified at a sink current of I V 48 mA to V V 0.6 V (open-collector output of an NPN transistor). The pull-up resistor feeding the opencollector output should be placed on the VME back plane. After the ACFAIL signal has gone low, the VME standard requires a hold-up time t h of at least 4 ms, before the 5.1 V output drops to 4.875 V, when the output is fully loaded. This hold-up time t h is provided by the internal input capacitance. Consequently the working input voltage and the threshold level V ti should be adequately above Vi min of the converter, so that enough energy is remaining in the input capacitance. If V i is below the required level, an external hold-up capacitor (C i ext) should be added; refer to the formulas below: Vt i = 1 EK LK Unit 61 97 120 VDC 1.1 2.7 4.2 ms Note: Option V2 and V3 can be adjusted by the potentiometer to a threshold level between Vi min and Vi max. A decoupling diode should be connected in series with the input of AK - FK converters to avoid the input capacitance discharging through other loads connected to the same source voltage. Option V operates independently of the built-in input undervoltage lockout circuit. A logic "low" signal is generated at pin 20, as soon as one of the monitored voltages drops below the preselected threshold level V t. The return for this signal is S-. The V output recovers, when the monitored voltages exceed V t + Vh . The threshold level V t i is either adjustable by a potentiometer, accessible through a hole in the front cover, or adjusted in the factory to a determined customer-specific value. Refer to table 26. V output (V0, V2, V3): Pin V is internally connected to the open collector of an NPN transistor. The emitter is connected to S-. V V 0.6 V (logic low) corresponds to a monitored voltage level (V i and/or Vo) <V t. I V should not exceed 50 mA.
