TRE and TRE..TK Series single-phase
transformer controllers
General remarks:
The TRE and TRE..TK series of transformer controllers for single phase
AC fans and motors, provide energy saving speed control without the creation of addi-
tional motor noise which you get with most electronic controllers. Vacuum impregnation
further reduces electrical noise from the transformers. Available for total load current of
up to 7.5 Amps, a rotary switch selects one of 5 different voltages.
The standard product has a simple fan/motor connection without provision for thermal
overload protection. Use of a separate motor protection device is recommended.
The TK version has connections for motor thermal overload protection. When connected,
an overheat condition will cause the motor supply to trip off. It can only be restarted after
the motor has cooled and either power disconnected from the controller or the selector
switch cycled through the off setting.

General remarks:
These manual, single-phase electronic control devices
provide a simple solution to speed controlling single or multiple fans, it has a
manual dial, which can alter the fan speed from a minimum setting ( factory
set to approx 20%) to 100%.
