OM-110 Power Limiting Relay

OM-110 power limiting relay is used for continuous control of single phase active or full power.

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.
