The REVO RT is a compact power controller unit, which integrates inside a single phase static group for each loop for control of the electrical power. Each unit manages 3 independent control loops. The unit can be purchased with the diagnostic functions for the load and for the SCRs. In this case there is a amperometric transformer for each channel. Each power channel is always equipped with extra rapid fuses . The power inside the unit, current transformer and extra rapid fuses in a single unit save a considerable space inside the panel and time for wiring . Available in the following currents: 35, 50, 75 and 90A with maximum voltages 480V and 600V.
