OM-110 Power Limiting Relay
OM-110 power limiting relay is used for continuous control of single phase active or full power.
The measured power range is between 0 and 20 kW or between 0 and 20 kVA.
OM-110 rejects the load in case the user-set maximum allowed load consumption power level is exceeded (with a set rejection time),and subsequently activates the load automatically (with a set activation delay time, or an option to block reclosing).
Potentiometers and DIP-switches installed in the front panel allow the user to set the following values:
- maximum allowed power level;
- relay activation time;
- automatic reclosing delay time.
The load consumption is measured without electrical opening, using an integrated current sensor.
OM-110 relay can be used in the following capacities:
- digital wattmeter (active or full power meter);
- load consumption limiting relay.
OM-110 is powered by the voltage measuring circuits.
