Overview

Three-phase voltage monitor monitors overvoltage and undervoltage. In addition to its own supply voltage, the relay monitors the presence of the neutral conductor, the undervoltage and the overvoltage (separate setting). Each threshold has its own adjustable delay. If a voltage fault occurs, the corresponding relay (one undervoltage and one overvoltage output) opens after the delay set by the user. If the neutral conductor fails, the two relays open immediately, without waiting for the delay. Approvals: UL and CSA.
