Power consumption limiters OM-631

Power consumption limiters OM-631


Adjustable operating power 200-1000 VA. With a constant return time. On rail TH-35.
Power consumption limiters are devised for the automatic disconnection of power from the circuit of single-phase wiring systems once the rated power consumption of the receivers incorporated into the system is exceeded.

The limiter enables the user to supply power to the circuit if the total consumed power applied to the receivers constituting the system is lower than the preset value on the limiter's scale. Once the rated power consumption threshold in the controlled circuit is exceeded, the element is automatically disconnected from the power source. The supply is reinstated automatically once the preset time lapses. If the value of power consumption remains over the rated input, the power supply to the circuit is cut off again.

Power limiter should not be used in systems with electronic ignition (energy saving lamps), pulse power supplier and other devices generating higher harmonics from 3 upwards.
