Eliminates AC hum & Coil burnout

solenoid-saver

Solenoid-Saver^® eliminates AC hum and reduces heat generation for many types of solenoids.
Controlled application of current prevents coil burnout if high pull-in/low holding current AC or DC solenoids fail to pull-in completely.
Can adapt high pull-in low holding current solenoids to special voltages & frequencies 12V to 250V DC or 12V to 240V AC wideband 25-800Hz.
Optional optical isolated control input 4 to 10V, 5MA, 20 usec or more (or other control voltages) to actuate any high current solenoid directly by computer or other low power signal source.
For coils of 1 ohm to 3,500 ohms DC resistance requiring up to 70 amps during pull-in up to 120 milliseconds. Basic solenoid coil voltage and resistance must be specified.
Eliminates heat producing dropping resistors, bypass switch, dual coils, laminations, & shading coils.
Can increase pull-in and holding force of many types of solenoids.
Optional stored energy to delay solenoid release on loss of power.
Can be used as an added accessory to existing solenoid installation to eliminate AC hum, lower coil temperature and prevent coil burnout.
Optional high speed, 1 microsecond sensing, 1-10 millisecond actuation with stored energy Solenoid-Saver^®

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.
