PBE Series True RMS 3-Phase Sequence Voltage Band Monitor Relay

About the PBE Series True RMS 3-Phase Sequence Voltage Band Monitor Relay from the ATC Diversified Electronics division of Marsh Bellofram Corporation:

In today’s industrial environment, Line Noise and Power Line Harmonics are becoming an increasing problem. True-RMS detection may be necessary for achieving accurate Line Voltage measurement. With normal operating voltages applied in the proper ABC sequence, the internal relay will energize (PICK-UP). When the voltages on any or all phases fall outside the preset Over/Under trip points for longer than the Drop-Out Time delay, the relay will de-energize (DROP-OUT). When line conditions return to normal, the PBE Series Monitor automatically resets and the internal relay energizes.
