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 80 V are specially
designed for secondary switched and battery-driven appli-
cations. The standard case design with heat sink allows op-
eration at nominal load up to 71°C without additional cool-
ing, 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.
Connector type according to DIN 41612:
– H15 for output current up to 16 A
– H15 S4 with four high current jacks for output current
≥ 20 A
