PFM 1250 monitor circuit
Description
The PFM 1250 is designed to monitor
performance of one 12 or 24VDC PAPST fan.
The fan speed is monitored by the continual
checking of the current commutation pulses.
As the fan speed reduces, indicating that some
external obstruction is affecting the fans
performance, a fan fail indication is triggered
via an LED output.
This is a non-latching output signal and as soon
as the fan speed returns to normal the LED
signal switches off.
Mounting is via a 8 pin card frame on 0.1 inch
centres, and the PFM 1250 can be mounted
directly onto a customer’s own pcb, (where
only one fan is being monitored), or onto the
PCM 1000 as a component part of a system
to monitor from 2 to 6 PAPST fans.

Pin length 10mm
When assembling the PFM 1250 into the
PMB SO (motherboard) for multiple fan
monitoring, the white spot on the chip
(Pin 1) should be aligned with the white
spot on the board.
Note this product line is currently being expanded. Please contact the PAPST plc Technical
Department for the latest information and application advice.
