Relay monitors phase shift between current and voltage in 3-phase or 1-phase networks - evaluates COS φ (replacement COS-1).
The relay is designed to monitor overload/relieve the motors.
Relay is designed for 3 x 400/230 V circuits.
Galvanically isolated power supply AC 230 V, AC 110 V, AC 400 V or AC/DC 24 V.
Adjustable upper and lower level COS φ.
Possibility to extend the current range using a current transformer.
Two output relays (for each level independent).
Adjustable delay eliminating engine start-up.
