Power Management System (Power Limiter)

These Power Management System (Power Limiter) is designed for the following applications:
- Load protection at poor parameters of the mains;
- Complete load cut-off in case if power usage exceeds the main threshold within the user-set time period
- Partial load cut-off in case if power usage exceeds the additional threshold within the user-set time period
- Measurement and indication of 3-phase electric circuit (delta voltage and mesh voltage RMS values, positive phase, negative phase and zero phase sequence voltages, phase currents RMS values; active power, reactive power, apparent power, power factor (cos ));
- Metering display (kW/h, kVA/h, kVAr/h)
- Fault warning;
- Remote load on/ off via RS-232 & RS485 Modbus interface or an external emergency switch.
OM-310 operates under loads ranging from 2.5 kW to 450 kW, including networks with insulated neutral.
OM-310 device provides the following types of load protection:
- When the mains voltage is of poor quality (impermissible voltage surges, phase loss, incorrect phase
sequence and phase "coincidence", phase/line voltage imbalance)
- When maximum specified current in any load phase is exceeded
- Against ground leakage (earth fault)

Communication:
- Control and parameters monitoring via RS-485 MODBUS protocol and via RS-232 interface,
- Free monitoring and controlling (programming) software provided.
