Switched-mode PSU for DC fans

25 October 2000 Power Electronics / Power Management

The switched-mode power supply PS60 from Papst was designed especially for the voltage supply of electronically commutated Papst DC fans. The PS60 is also highly suitable for supplying DC small drives and other small consumers with current.

The switched-mode current supply is an integrated unit and the output voltage can be controlled for temperature-dependent fan operation. Voltage can be varied via an external temperature sensor.

The output power is 60 W max; output voltage from 12 to 24 V d.c. - settable via external resistor or potentiometer.

It is short-circuit-proof (constant current) and optional PCB with additional functions, eg speed monitoring with alarm signal output for critical speeds is available.
