400-480V 3 phase monitor
Isolated 10Amp SPDT relay
The SSAC DLM911 Series DIN rail mounting three phase voltage monitors continuously measures the voltage of each of the three phases. Its circuit design separately senses Phase Reversal, Undervoltage, Overvoltage, 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.
Operation: The output relay is energized and the LED glows when all voltages are acceptable and the phase sequence is correct. Undervoltage and voltage unbalance must be sensed for a continuous trip delay period (2-20 seconds) before the relay and the LED are de-energized. Re-energization is automatic upon correction of the fault condition. The output relay will not energize if a fault condition is sensed as power is applied.
See the attached spec sheet photos above for a complete description of its capabilities.
