DEMAND CONTROLLER OVERCURRENT-EARTH FAULT RELAY OM-310

OM-310 Numeric Power Management System is used for:

  • Power Monitoring
  • Demand Controlling
  • Generator protection
  • Overcurrent protection
  • Earth leakage protection
  • Voltage monitoring
  • Complete load rejection when the power consumption exceeds the main threshold for a user-set time
  • Partial load rejection when the power consumption exceeds the main threshold for a user-set time
  • Measurement and indication of three-phase electric circut parameters (active values of phase and line voltages)
  • Positive, negative and zero phase sequence voltages; active phase current values; active, reactive and full power load consumption, power factor
  • Emergency signaling
  • Remote monitoring and load activation/deactivation via the RS-232/RS485 interface or external switch

The device allows working with a load of 2.5 – 30 kW with the use of integrated current transformers, and with a load of up to 450 kW with the use of external current transformers, including in networks with an insulated neutral.

POWER CONTROLLER & CURRENT-VOLTAGE MONITORING RELAY OM-163

ОМ-163 is designed to protect (disconnect) the equipment (load) connected to it in the following cases:
− exceeding the threshold value of the controlled parameter;
− deviation of the mains voltage from the set values;
− excess of the temperature of the contact group (85 °С).

ОМ-163 can be used as:
− power consumption limiting relay;
− voltage relay;

— current overload relay;

− energy meter (indication of total, active, reactive power, current consumption and mains voltage).

ОМ-163 is powered by the circuit that feeds the load. ОМ-163 displays the value of the parameters and the status of the relay using LED indicators and display.
