The S 1000/2000 Series of DC-DC converters represents a flexible range of power supplies for use in advanced electronic systems. Features include full power factor correction, good hold-up time, high efficiency and reliability, low output voltage noise, and excellent dynamic response to load/line changes.

The converters are protected against surges and transients occurring at the source lines. An input over- and undervoltage lockout circuitry disables the outputs, when the input voltage is outside of the specified range. Input inrush current limitation is included for preventing circuit breakers and fuses from tripping at switch-on.

All outputs are overload, open- and short-circuit proof and protected by a built-in suppressor diode. The outputs can be inhibited by a logic signal applied to connector pin 18. If the inhibit function is not used, pin 18 must be connected with pin 14 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 output isolation is provided. The converters are designed and built according to the international safety standards IEC/EN 60950. They have been approved by the safety agencies TUV and UL (for USA and Canada).

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
