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.

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.
