for High Voltage Relays or other Solenoid Actuated Devices
Upon loss of power provides stored energy for delay to close for a normally closed or delay to open for a normally open relay or contactor, or delay loss of holding force in any solenoid actuator upon loss of actuator power.
Also with stored energy, high speed actuation is available with or without loss of power with 1-20 microseconds trigger pulse and actuator time as fast as 1-4 milliseconds.
Available for standard 115V, 208V, or 240V 50/400 Hz actuation (other AC & DC voltages available).
Provides same AC hum elimination, reduced coil temperature and coil burnout prevention as standard Solenoid-Saver®. Solenoid can not be energized at below 60% of line voltage. Other minimum actuation settings available.
Standard delay to close or open on loss of AC line below minimum voltage is obtainable from 1 to 3 or 4 to 9 seconds for specific HV Relay for standard unit. Other delays available.
