Independent Phase Regulation

In three phase applications, the incoming voltage level of each phase is frequently unbalanced (e.g. Phase A = 440v, Phase B = 469v, Phase C = 453v). This unbalance can cause many electric devices, such as motors, to run inefficiently which, in turn, causes them to run at higher temperatures and wear out prematurely. Units that offer independent phase regulation provide much more accurate voltage regulation and a higher level of protection than units that assume that the phase voltages are balanced.
