Power factor monitoring relay – COS-2

    • RELAY MONITORS PHASE SHIFT BETWEEN CURRENT AND VOLTAGE IN 3-PHASE OR 1-PHASE NETWORKS
    • 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

• 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 / 230V circuits
