3-PHASE MONITORS

General Description

The 3-phase monitor designed by PDI Tech Corp., provides protection from phase loss, phase unbalance and phase reversal. It is a device that is designed for continuously monitoring electric currents and detecting current loss in single-phase or three phase electric installations. It also provides an alarm signal or a relay contact closure when the current of one or more channels is below the threshold for a duration that can be preset from several seconds to several minutes.
