Description

Power factor monitoring relay COS-1Relay monitors phase shift between current and voltage - cos-φ in 3-phase and also 1-phaseDESCRIPTION The relay is designed to monitor the overload / relief of motors, pumps, elevator systems. MEMORY function, “RESET” button on the frontal panel. Supply set 3x400 V. 2 output relays, independent for each level. Adjustable delay to eliminate short peak overloading Adjustable range and bottom level cos-φ, of power factor between 0.1- 0.99. It is possible to connect current transformer in front of the device. This enables increase of current range. Adjustable delay to eliminate starting of motor Selectable hysteresis 5 or 10%.TECHNICAL PARAMETERS Supply voltage AC 230 V, AC 110 V, AC 400 V or AC/DC 24 V, galvanically separated. Output contact: 2x changeover 16 A/250 V AC1 (AgNi, 4 000 VA) . 3-MODULE, DIN rail mounting.
