Power Management System (Power Limiter) - Plastic Metal, 2.5-450 Kw, 3-phase | Load Protection, Overload Cutoff, Energy Metering, Remote Control, Modbus Communication

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.
