United Automation, TPSR-25, Thyristor Power Controller

Description:

The TPSR series of solid-state temperature controllers are designed to regulate the fan speed in
heating, ventilating and air conditioning systems. The NTC thermistor replaces the conventional
thermostat thus giving continuous proportional control of the blower speed in response to the
temperature. Thus, with the NTC thermistor connected, as the monitored temperature rises, the fan
speed increases. The TPSR also incorporates a set minimum fan speed, for the gentle circulation of air
through the heat exchanger and to provide protection of the motor bearing.

APPLICATIONS
Suitable for quartz lamps, conventional resistive heating elements, including ovens, moulders, dryers
and some other inductive loads.

FEATURES
· Simple installation.
· Rugged and compact.
· 25A capability with heatsink.
· Internal snubber
