Power factor monitoring relay - COS-2

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.
