H Series Data Sheet 50 Watt DC-DC Cassette Converters Features Wide input voltage ranges up to 60 VDC 1, 2, or 3 outputs up to 48 VDC Class I equipment * Wide input voltage range suitable for battery operation * Efficient input filter and built-in surge and transient suppression circuitry * Outputs individually isolated * Outputs fully protected against overload 111 4.37" 3U 39 1.54" 8TE Safety according to IEC/EN 60950 168 6.6" Description The H series of DC-DC converters represents a broad and flexible range of cassette power supplies for use in advanced electronic systems. Features include high efficiency, reliability, and reasonable output voltage noise. The converter inputs are protected against surges and transients occuring at the source lines. Input over- and undervoltage cut-out circuitry disables the outputs if the input voltage is outside the specified range. All outputs are open- and short-circuit proof and are protected against overvoltages by means of built-in suppressor diodes. The outputs can be inhibited by a logic signal applied to the connector pin 2 (i). If the inhibit function is not used, pin 2 should be connected to pin 23 to enable the outputs. safety agencies TUV and UL (USA and Canada). The case design allows operation at nominal load up to 50 C in a free air ambient temperature. If forced cooling is provided, the ambient temperature may exceed 50 C, but the case temperature should remain below 80 C under all conditions. A temperature sensor generates an inhibit signal which disables the outputs if the case temperature TC exceeds the limit. The outputs are automatically re-enabled when the temperature drops below the limit. Various options are available to adapt the converters to individual applications. The converters may either be plugged into 19-inch rack systems according to DIN 41494, or be chassis mounted. LED indicators display the status of the converter and allow visual monitoring of the system at any time. Full input-to-output, input-to-case, output-to-case, and output-to-output isolation is provided. The converters are designed and built according to the international safety standard IEC/EN 60950 and have been approved by the Table of Contents Page Page Description ....................................................................... 1 Model Selection ............................................................... 2 Part Number Description and Product Marking ............... 2 Functional Description ..................................................... 3 Electrical Input Data ......................................................... 4 Electrical Output Data ...................................................... 5 Auxiliary Functions ........................................................... 8 Electromagnetic Compatibility (EMC) ............................ 10 Mechanical Data ............................................................ 11 Immunity to Environmental Conditions ........................... 12 Safety and Installation Instructions ................................ 12 Description of Options .................................................... 15 Accessories .................................................................... 19 REV.

REV. MAR 27, 2006 Page 2 of 19 www.power-one.com H Series Data Sheet 50 Watt DC-DC Cassette Converters Functional Description The input voltage is fed via an input filter to the input capacitor. This capacitor sources a single-transistor forward converter. Each output is powered by a separate secondary winding of the main transformer. The resultant voltages are rectified and their ripples smoothed by a power choke. The control logic senses the main output voltage Vo1 and generates, with respect to the maximum admissible output currents, the control signal for the primary switching transistor. This signal is fed back via a coupling transformer. The auxiliary outputs Vo2 and Vo3 are unregulated. Each auxiliary output's current is sensed and transferred to the main control circuit using a current transformer. If one of the outputs is driven into current limit, the other outputs will reduce their output voltages as well because all output currents are controlled by the same control circuit. 03067 1 Main control circuit 1 29 5 D/V 14 R 17 G Forward converter approx. 70 kHz 23 Input filter Vi- i 20 Y Vi+ 2 32 Y 26 CMKT 14 Current limitation output 2 17 CMKT 8 Current limitation output 3 11 Y 1 Y Y Single output modules H1000 (R input) Fig. 1 DC-DC converter block diagram REV.

When checking this function the absolute maximum input voltage rating Vi abs must be carefully considered (see table: Electrical Input Data). Between Vi min and the undervoltage lockout level the output voltage may be below the value defined in table: Output data (see: Technical Information: Measuring and Testing).

Voltage suppressor diodes (which under worst case condition may become a short circuit) provide the required protection. The suppressor diodes are not designed to withstand externally applied overvoltages. Overload at any of the outputs will cause a shut-down of all outputs.

Outputs two and three of a triple-output model can be connected in parallel. In parallel operation, one or more of the main outputs may operate continuously in current limitation which will cause an increase in case temperature. Consequently, a reduction of the maximum ambient temperature by 10 K is recommended. Main or auxiliary outputs can be connected in series with any other output of the same or another converter. In series connection, the maximum output current is limited by the lowest current limit. Output ripple and regulation values are added. Connection wiring should be kept as short as possible. If output terminals are connected together in order to establish multi-voltage configurations, e.g. +5.1 V, 12 V etc. the common ground connecting point should be as close as possible to the connector of the converter to avoid excessive output ripple voltages. REV. MAR 27, 2006 Page 6 of 19 www.power-one.com H Series Data Sheet 50 Watt DC-DC Cassette Converters Thermal Considerations Io /Io nom 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 50 C (e.g. 65 C) if TC max is not exceeded. For -2 units at an ambient temperature TA of 65 C with only convection cooling, the maximum permissible current for each output is approx. 50% of its nominal value as per figure. Forced cooling 1.0 0.9 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0 05032 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 on 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. Convection cooling TC max TA min 40 50 60 70 80 TA [ C] Fig. 5 Output current derating versus temperature for -2 units. Thermal Protection A temperature sensor generates an internal inhibit signal which disables the outputs if the case temperature exceeds TC max. The outputs are automatically re-enabled if the temperature drops below this limit. Output Response The reaction of the outputs is similar whether the input voltage is applied or the inhibit is switched low. An output voltage overshoot will not occur when the converter is turned on or off.

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. See also: Technical Information: Installation and Application. In order to avoid possible damage, any penetration of liquids (e.g. cleaning fluids) is to be prevented, since the power supplies are not hermetically sealed. Connection to the system shall be made via the female connector H11 (see: Accessories). Other installation methods may not meet the safety requirements. All DC-DC converters are provided with pin no. 26 ( ), which is reliably connected with their case. For safety reasons it is essential to connect this pin with the protective earth of the supply system if required in: Safety of operator accessible output circuit. Ensure that a cassette failure (e.g. by an internal shortcircuit) does not result in a hazardous condition. See also: Safety of operator accessible output circuit. To prevent excessive current flowing into the cassette (e.g. by an internal short-circuit), an external fuse suitable for the application and in compliance with the local requirements should be installed in the wiring to one or both input pins (no. 29 and/or no. 32). See also: Input Fuse. Important: Whenever the inhibit function is not in use, pin no. 2 (i) should be connected to pin no. 23 (Vo1-) to enable the output(s). Do not open the modules, or guarantee will be invalidated. Make sure that there is sufficient airflow possible for convection cooling. This should be verified by measuring the case temperature when the unit is installed and operated in the end-use application. The maximum specified case temperature TC max shall not be exceeded. See also: Thermal Considerations. Standards and Approvals 12H to 48H DC-DC converters correspond to class I equipment. All types are UL recognized according to UL 1950, UL recognized for Canada to CAN/CSA C22.2 No. 950-95 and TUV approved to IEC/EN 60950 standards. The units have been evaluated for: * Building in * Supplementary insulation between input and case and double or reinforced insulation between input and output, based on 250 VAC and 400 VDC * Operational insulation between output(s) and case * Operational insulation between the outputs * The use in a pollution degree 2 environment * Connecting the input to a primary or secondary circuit with a maximum transient rating of 2500 V.

MAR 27, 2006 Page 13 of 19 www.power-one.com H Series Data Sheet 50 Watt DC-DC Cassette Converters Safety of operator accessible output circuit If the output circuit of a DC-DC converter is operator accessible, it shall be a SELV circuit according to the IEC/ EN 60950 related safety standards. Since the H series DC-DC converters provide double or reinforced insulation between input and output, based on a rated primary input voltage of 250 VAC and 400 VDC only operational insulation is needed between the AC mains and the input of the DC-DC converter. This means that there is no need for an electrical isolation between the AC mains circuit and the DC-DC converter input circuit to cause the output of an H series DC-DC converter to be a SELV circuit. Only voltage adaptation and rectification to the specified input voltage range of the DC-DC converter is needed. The following table shows some possible installation configurations, compliance with which causes the output circuit of the DC-DC converter to be a SELV circuit according to IEC/EN 60950 up to a configured output voltage (sum of nominal voltages if in series or +/- configuration) of 36 V. However, it is the sole responsibility of the installer to assure the compliance with the relevant and applicable safety regulations. More information is given in: Technical Information: Safety.

The power supplies provide full nominal output power with convection cooling. D Undervoltage Monitor The input and/or output undervoltage monitoring circuit operates independently of the built-in input undervoltage lockout circuit. A logic "low" (JFET output) or "high" signal (NPN output) is generated at pin 5 as soon as one of the monitored voltages drops below the preselected threshold level Vt. The return for this signal is Vo1- (pin 23). The D output recovers when the monitored voltage(s) exceed(s) Vt+Vh. The threshold level Vt is adjustable by a potentiometer, accessible through a hole in the front cover. Option D exists in various versions D1 to D8 as shown in the following table.

This option defines an undervoltage monitoring circuit for the input or the input and main output voltage equivalent to option D, and generates the 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 VV -0.6 V (open-collector output of a NPN transistor). The pull-up resistor feeding the open-collector output should be placed on the VME backplane. 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 5.1 V output is fully loaded. This hold-up time t h should be provided by an external input capacitance. Consequently the working input voltage and the threshold level Vt i should be adequately above the minimum input voltage Vi min of the converter so that enough energy is remaining in this capacitance. If the input voltage is below the required level, an external hold-up capacitor (C i ext) should be added.
