Features include high efficiency, reliability, and low output voltage noise. output isolation is provided. The converters are designed and built according to the international safety standard IEC/EN 60950-1 and have been approved by the safety agencies TUV and UL. The converter inputs are protected against surges and transients occuring at the source lines. An input over- and undervoltage lockout circuit disables the outputs, if the input voltage is outside the specified range. An inrush current limitation prevents circuit breakers and fuses from tripping at switch-on. 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. 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). If the inhibit function is not used, pin 2 should be connected to pin 23 to enable the outputs. 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 Table of Contents Two options are available to adapt the converters to individual applications (D, V). The converters may either be plugged into 19" rack system according to IEC 60927-3 or be mounted onto a chassis or a plate.

Functional Description The input voltage is fed via an input fuse, an input filter, and an inrush current limiter 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 and an output capacitor. The main control circuit 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 transferred to the primary side by a coupling transformer. The auxiliary output voltages Vo2 and Vo3 are tracking. Each auxiliary output's current is sensed 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 main control circuit.

Subsequent switch-on cycles within a short interval will cause an increase of the peak inrush current due to the warming-up of the NTC resistor. Input Fuse A slow-blow fuse (Schurter SPT 2.5 A, 250 V, size 5 x 20 mm) mounted inside of the converter protects against severe defects. The fuse is not accessible by the user.

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. 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 allow TA to pass over 50 C, if TC max is not exceeded. 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; see fig. 9 . A temperature sensor generates an internal inhibit signal disabling the outputs, when the case temperature exceeds TC max. The outputs automatically recover, when the temperature drops below this limit. of the case temperature TC. Consequently, a reduction of the max. ambient temperature by 10 K is recommended. Both outputs of a double-output converter may be connected in parallel without any restriction. Note: If output 2 of a double-output converter is not used, we recommend to connect it in parallel with the main output. Output 2 and output 3 of a triple-output converter may be connected in parallel without any restriction. Note: If the output 2 or 3 of a triple-output converter is not used, we recommend to connect it in parallel with the other auxiliary output. 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 in order to avoid excessive output ripple voltages. Auxiliary outputs of different converters should not be connected in parallel!

It is important to assure that the main output of a multiple-output converter is forced to supply a minimum current of 10% of Io nom to enable correct operation of its own auxiliary outputs. In parallel operation, one or more of the main outputs may operate continuously in current limitation, causing an increase BCD20019 Rev AA Page 8 of 21 www.power-one.com H Series Data Sheet 70 Watt AC-DC Converters (R) Auxiliary Functions 06115a i Inhibit N The outputs of the converters may be enabled or disabled by means of a logic signal (TTL, CMOS, etc.) applied between the inhibit input i and the negative pin of output 1 (Vo1-). In systems with several converters, this feature can be used, for example, to control the activation sequence of the converters. If the inhibit function is not required, connect the inhibit pin 2 to pin 23 to enable the outputs (active low logic, fail safe). The response times are specified in fig. 12.

Protection Degree Not connected, if option neither option D or V is fitted. Leading pin Condition: Female connector fitted to the converter. Installation Instructions The H Series converters are components, intended exclusively for inclusion within other equipment 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 H11. Other installation methods may not meet the safety requirements. The converters are provided with pin no. 26 ( ), which is reliably connected with the case. For safety reasons, it is essential to connect this pin with the protective earth of the supply system. A non-accessible input fuse is connected in the line to pin 32 (L ). Since this fuse is designed to protect the converter in case of an overcurrent and does not necessarily cover all customer needs, an external fuse suitable for the application and in compliance with the local requirements may be necessary in the wiring to one or both input pins (no. 29 and/or no. 32), particularily if the phase or neutral line cannot be assigned to the corresponding terminals. Important: If the inhibit function is not in use, pin 2 (i) should be connected with pin 23 (Vo-) to enable the output(s). Caution: Do not open the converters, or warranty will be invalidated. BCD20019 Rev AA N L In order to avoid possible damage, any penetration of liquids (e.g., cleaning fluids) has to be prevented, since the power supplies are not hermetically sealed. IP 40: All models, except those with options D or V with potentiometer. IP 20: All models other models. Standards and Approvals The converters correspond to class I equipment and have been approved according to the standards IEC 60950-1 and EN 60950-1. The converters have been evaluated for: * Class I equipment * Building in * Basic insulation between input and case and double or reinforced insulation between input and output, based on the input voltage of 250 VAC or 400 VDC * Functional insulation between output(s) and case * Functional insulation between the outputs * Pollution degree 2 environment * Overvoltage catagory II * Altitude up to 2000 m The converters are subject to manufacturing surveillance in accordance with the above mentioned standards and with ISO 9001:2000. Isolation The electric strength test is performed in the factory as routine test in accordance with 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.

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 V t. The return for this signal is Vo1- (pin 23). The D output recovers, when the monitored voltages exceeds V t + 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 - D8 as shown in table 15.

VD - 0.4 V (logic low) corresponds to a monitored voltage level (Vi and/or Vo1) < Vt. 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. If V i is monitored, the internal input voltage after the input filter and rectifier is measured. Consequently, this voltage differs from the voltage at the connector pins by the voltage drop V ti across input filter and rectifier.

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 IV = 48 mA to VV - 0.6 V (open-collector BCD20019 Rev AA output). 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 is provided by the internal input Page 17 of 21 www.power-one.com H Series Data Sheet 70 Watt AC-DC Converters (R) capacitance. Consequently, the working input voltage and the threshold level Vti should be adequately above the minimum input voltage Vi min of the converter, so that enough energy is remaining in the input capacitance.
