Technipower Autotransformers
* Only autotransformer on the market that is based on original Variac
design
* Efficient, trouble-free device for controlling AC voltage and any other
quantities that derive from AC voltage: heat output, light intensity, motor speed and
power supply outputs
* This autotransformer has a transformation ratio that can be smoothly and
continuously changed so that the output of the unit can be controlled from zero to line
voltage or even higher
* Durable, because they run cool
* Independent of load size or power factor - the voltage to the load
changes little from full load to no load
* Distortion free - they add no harmonic distortion to the power line
* Reliable - special contact surface reduces brushtrack deterioration for
long life
* Easy to install - all mounting hardware is included, a wiring diagram is
on the terminal plant and conduit knockouts are included on enclosed models
* Versatile - hundreds of standard versions are available to satisfy
various line frequency, voltage and phases requirements, load size and mounting demands
(including portable models); they can be supplied with motor drives, ball bearings and in
ganged assemblies to increase basic line-voltage and load current ratings; militarized
models for 400 Hz operation are available
* Safe - safety is assured by Underwriter's Laboratory listing and
Canadian Standards approval for many models
