The BELOTTI autotransformer is an efficient, trouble-free device for controlling A.C. voltage. Unlike most transformers, our voltage regulator has a transformation ratio that can be smoothly and continuously changed so the output of the unit can be controlled from zero to line voltage or even higher.
Features:
EFFICIENT - transforms power more efficiently than rheostats
DURABLE - because it runs cool (40/50° C max)
OVERLOAD-ABLE withstands 1000% overloads short term
- Independent of load size or power factor - voltage to the load changes little from full load to none.
- Produce an adjustable output voltage that is a sine wave. Only the voltage magnitude is changed; the shape of the voltage is not distorted.
- Handle all load power factors.
- Can be used to adjust banks of capacitors and/or inductors
