Power factor (cos φ) monitoring relay COS-2

Relay monitors phase shift between current and voltage in 3-phase or 1-phase networks - evaluates COS φ (replacement COS-1).

EAN: 8595188155434 (230V) | Code: 5543 (230V)
EAN: 8595188152365 (400V) | Code: 5236 (400V)

DESCRIPTION

  • 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.
