DCP Fan Controller
1. Introduction
The ebm-papst UK Ltd DCP Fan Controller has been designed to give end users a low cost, simple and user-
friendly controller for use with the large range of DC fans with PWM speed control inputs.
The DCP Fan Controller is designed to operate at the same supply voltage as the fan, therefore a range of
controllers in 12/24 and 48 volts are available.

Temperature is measured via an NTC thermistor with a 25
C of 100K. This is supplied in the form of a 2m long
lead so that the controller and sensor can be remotely placed.

The unit is shipped with one of two pre-set temperature profiles that cover 20
C to 40
C or 35
C to 55
C (details
in section 2.)
The DCP Fan Controller also monitors the Tacho output from the fan and then generates an alarm output if a
fan fail is detected.
The DCP Fan Controller is fitted with an open drain fail safe alarm output as standard (see section 2). This alarm
is activated if a fan fail is detected or if the upper temperature limit is reached. The controller will also generate
an alarm if it detects either an open or short circuit on the NTC temperature input. During alarm conditions the
fan will be run at full speed.
