| "RTC/220" automatic three phase voltage stabilisers with electronic control and INDEPENDENT VOLTAGE REGULATION ON EACH PHASE are essential for the use with any unbalanced loads. The stabilisers use three control circuits and three servo-motors; each phase is individually regulated, making the voltage rigorously constant near the rated value. The "RTC/220" stabilisers are ideal for any application and vary silent, totally free from magnetic leakage and do not introduce harmonic distortion. Neutral wire is not necessary for a proper operation: this stabiliser has been designed to work with 220V, three wires lines. "RTC/220" staiblisers are equipped with an automatic 3-poles circuit breaker, digital voltmeter with input and output voltage reading on each phase, fine voltage regulation on each phase. |
