OM-110-01 Power Limiting Relay
OM-110-01 Power Limiting Relay with integrated voltage relay is designed for continuous control of the active or full power of single-phase load.
The measured power range is between 0 and 20 kW or between 0 and 20 kVA.
The OM-110-01 performs load turn off in case the user-set maximum allowed load consumption power level is exceeded (with a specified offtime),and further automatic turn on (with a specified activation delay time or with block of restart (reclosing).
Potentiometers and DIP-switches are installed on the front panel which allow the user to set the following values:
- level of maximum allowed power;
- relay activation time;
- automatic restart (reclosing) delay time.
Power consumption is measured without electrical open, using an integrated current sensor.
The OM-110-01 relay can be used as follows:
- digital wattmeter (active or full power detector);
- power consumption limiting relay.
The OM-110-01 is powered by the voltage measuring circuits.
