ABB RLM911 Voltage Monitor. 3-Phase | 480 V AC Line Voltage | Line Monitor Simple Type: Voltage Monitor

The SSAC RLM911 Series of encapsulated three phase voltage monitors continuously measures the voltage of each of the three phases. Its circuit design separately senses Phase Reversal, Undervoltage, and Voltage Unbalance including Phase Loss. Protection is assured during periods of large average voltage fluctuations, or when regenerated voltages are present. Both Delta and Wye systems can be monitored; no connection to neutral is required.
