100 Watt AC-DC Converters with PFC

Summary

The S 4000/S 5000 series of AC-DC converters represents

a ﬂexible range of power supplies for use in advanced elec-

tronic systems. Features include full power factor correc-

tion, high efﬁciency, high reliability, low output voltage noise

and excellent dynamic response to load/line changes.

The converter inputs are protected against surges and tran-

sients occurring at the source lines. An input over- and

undervoltage lock-out circuitry disables the outputs if the

input voltage is outside the speciﬁed range. Inrush current

limitation is included preventing circuit breakers and fuses

from being damaged at switch-on.

All outputs are overload, open- and short-circuit proof and

are protected against overvoltages by means of a built-in

suppressor diode. The outputs can be inhibited by a logic

signal applied to the connector pin 18 (i). If the inhibit func-

tion is not used pin 18 must be connected to pin 14 to en-

able 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 modules are designed

and built according to the international safety standards

IEC/EN 60950 and have been approved by the safety

agencies LGA (Germany) and UL (USA). The UL Mark for

Canada has been ofﬁcially recognized by regulatory au-

thorities in provinces across 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.

A temperature sensor generates an inhibit signal which

disables the outputs if the case temperature T

the limit. The outputs are automatically re-enabled when

the temperature drops below the limit.

Various options are available to adapt the converters to in-

dividual applications.

The modules may either be plugged into 19" rack systems

according to DIN 41494, or be chassis mounted.
