COS-1:Power factor monitoring relay

  • relay monitors phase shift between current and voltage - cos-φ in 3-phase and also 1-phase mains for monitoring overload/unloading of motors
  • supply set 3x400 V
  • function “MEMORY” - manual reset - button on front pannel
  • it is possible to connect current transformer in front of the device. This enables increase of current range

  • 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 0.1 - 0.99
  • adjustable delay to eliminate starting of motor
  • selectable hysteresis 5 or 10%
  • galvanically separated supply AC 230 V, AC 400 V or AC/DC 24 V
  • output contact: 2x changeover 16 A / 250 V AC1
  • 3-MODULE, DIN rail mounting
