Power factor monitoring relay - COS-2

Relay monitors phase shift between current and voltage in 3-phase or 1-phase networks

EAN: 8595188155434 (230V) | Code: 5543 (230V)
EAN: 8595188152280 (110V) | Code: 5228 (110V)

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
  • Adjustable MEMORY function
  • Relay is designed for 3 x 400 / 230V circuits
  • Two output relays (for each level independent)
  • Possibility to extend the current range using a current transformer
  • Adjustable upper and lower level COS φ.
  • Adjustable delay eliminating engine start-up

TECHNICAL PARAMETERS

  • Galvanically isolated power supply AC 230V, AC 110V, AC 400V or AC / DC 24V
  • Output contact 2x changeover 16A / 250V AC1
  • 3-MODULE design, mounting onto DIN rail.
