COS-2 - Power voltage: 24 V AC/DC
COS-2 - Power voltage: 24 V AC/DC
Power factor protecting relay
Description
COS-2 | Power factor protecting relay
-
Relay monitors phase shift between current and voltage in 3-phase or 1-phase networks - evaluates COS (replacement COS-1)
- The relay is designed to monitor overload/underload the motors
- Relay is designed for 3 x 400 / 230V circuits
- Galvanically isolated power supply AC 230V, AC 110V, AC 400V or AC / DC 24V
- Adjustable upper and lower level COS
- Possibility to extend the current range using a current transformer
- Adjustable MEMORY function
- Two output relays (for each level independent)
- Adjustable delay eliminating engine start-up
- Output contact 2x switches 16A / 250V AC1
- 3-MODULE design, mounting onto DIN rail.
