MONITORING RELAYS Ex9JP V-1 3P
The Ex9JP V-1 3P is voltage monitoring relay compatible with 3-phase 3-wire and 3-phase 4-wire systems. It effectively monitors voltage for 3-wire 155-500 V AC or 4-wire 90-228 V AC. The device offers adjustable parameters: upper and lower voltage levels; asymmetry; voltage and frequency hysteresis levels; delay after supply connection.
