SOLENOID-SAVER^®

Eliminates AC hum & Coil burnout

• 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^®

DELAYED ACTION 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.
