Circuit for Solenoid Valves, 12 or 24 VDC input

Preserve the life of your solenoid valves with this "hit and hold" circuit|Steps down DC voltage to 1/3 of input voltage|Minimizes heat generation|The CoolCube delivers a power step-down function to a solenoid valve. Using AMP or Molex connectors, it accepts either a 12 or 24 VDC input and passes the input on to the solenoid valve with full power for 110 msec. After 110 msec, the CoolCube drops the voltage and current to a level sufficient to hold the solenoid in the energized position, thereby minimizing power consumption and heat generation. The CoolCube can remain under power indefinitely without being damaged. When the power is cut, the valve is turned off immediately, as though the CoolCube were not in the system. The CoolCube permits placing an overdrive voltage on a solenoid valve. This means that a solenoid valve rated for 12 VDC can be energized with a voltage of 24 VDC. Since the CoolCube automatically drops the voltage after 110 msec, the solenoid will not be impaired in any way. Accepts 36 VDC maximum.
