thermal management systems
Speed Control
Alarm Functions and Outputs
Temperature dependent speed control is
provided for any number of PAPST DC fans or
blowers up to a total power capacity of 65W.
The control module makes use of up to
4 thermistors which can be located in the most
heat sensitive areas within the equipment.
The module provides linear control between
half and full speed. This is achieved by utilising
one of the four user selected temperature
programs available which sets temperature
parameters T1 (lower level) and T2 (upper
level). As the surrounding ambient temperature
rises, the module responds to the highest
temperature recorded by any one of the
thermistors. In the event of a thermistor failure,
the fans will run at full speed for fail safe
operation. A shutdown and stand-by mode for
low temperatures (T0) is also available which is
particularly useful for equipment exposed to
very cold ambient temperatures outdoors.
In the event of the measured temperature
exceeding the upper selected level T2, a dual
output alarm is activated, one output in the
form of a single pole change-over relay with
volt-free contacts and the other as an open
collector. The same dual alarm arrangement is
provided in the event of a thermistor failure.
An open collector output is also provided
should the module switch to shutdown/
standby mode.

become independently active if the speed
of its related fan falls below the selected

Fan speed is fully controlled and regulated by
the functionality of the power module. If the
input voltage fluctuates, for example due to
power fail or charge mode in a battery backup
system, the fans will continue to operate
in their temperature controlled state.

Four uncommitted alarm outputs are available.
Typical configurations include:
I. Upper temperature T2 reached
II. Over temperature alarm T3 should the
ambient temperature continue to rise
above T2
Description
The System 5000 has been developed with
the critical thermal needs of the equipment
designer in mind. It allows for maximum
control of the thermal profile required by
today’s sophisticated electronic equipment
while introducing an ‘environmentally friendly’
aspect to the design.

or heater/chillers can be switched on within the
customers’ system (power switching module).

Features
The System 5000 offers a modular approach
to environmental control providing:
Speed Control
Fan Monitoring
Temperature dependent speed control is
provided for up to 6 PAPST DC fans or
blowers with a combined power rating
governed by the power module. The control
module makes use of up to 8 thermistors
which can be located remotely with the
equipment in the areas deemed to be the
most sensitive.

•
Temperature dependant speed control
Multiple point temperature sensing
Regulated output allowing independent
control of fan speed over a wide

The System 5000 can be used in conjunction
with PAPST DC fans fitted with open collector
(/2) or TTL (/12) sense wires for fan
monitoring. The module will provide
‘fan failing’ monitoring for up to 6 PAPST DC
fans or blowers. If the speed of any fan falls
below a pre-programmed percentage of the
nominal speed, an alarm is triggered.

•
Fan fail monitoring
Fully programmable functionality
Fail safe operation
The control module can regulate the fan speed
linearly between half and full speed. This is
achieved by two customer defined temperature
settings, T1 (lower level) and T2 (upper level).
As the surrounding ambient temperature rises,
the system reacts to the highest temperature
recorded by any one of the thermistors. In the
event of a thermistor failure, the system can be
programmed to run fans at full speed for fail
safe operation.

PFM 1250 monitor circuit

•
Versions available for all 12 and 24VDC fans
Monitors current communication pulses
Can be used with PCM1000 to monitor
2 to 6 fans
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.
•
Compact design which can be mounted
on customer pcb.

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.

Description
With a minor change to the circuit board it is
possible to use up to 3 NTC resistors, which,
when connected to PAPST Variofans, provide
monitoring of temperature controlled fans.
The PCM 1000 provides an output which
illuminates a LED to indicate fan failure.
By combining both the PCM 1000 and 2000
several other options are available. These
include LED off at fan failure, TTL output which
goes from high to low in a fault condition,
and relay outputs in normally open/common/
normally closed variations. (The relay energises
in fault mode.)
