Variable Transformer

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
