Three-phase voltage monitor monitors over and under voltage.
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 value has its own adjustable delay.
If a voltage fault occurs, the corresponding relay (an undervoltage and an 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.
