Power factor monitoring relay COS-1

Relay monitors phase shift between current and voltage - cos-φ in 3-phase and also 1-phase

DESCRIPTION

  • 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.
