Summary

The PSS/PSK series of positive switching regulators is de-

signed as power supply modules for electronic systems.

Their major advantages include a high level of efficiency

that remains virtually constant over the entire input range,

high reliability, low ripple and excellent dynamic response.

Modules with input voltages up to 144 V are specially

designed for secondary switched and battery-driven

mobile applications. The standard case design with heat

sink allows operation at nominal load up to 71°C without

additional cooling, suitable for 19" rack or chassis

mounting.

Replacing the heat sink by an optional cooling plate B or B1,

allows chassis or wall mounting on top of a metal surface,

acting as heat sink.
