The energy-efficient CoolCube solenoid control module has been designed to allow the placement of an overdrive voltage on a solenoid valve, which can decrease valve response time, increase operating pressure, and reduce power consumption.

The compact module provides a step-down voltage to 1/3 of the input voltage. Its hit-and-hold circuit accepts either 12 or 24 Vdc input to energize the solenoid valve with full power for 110 milliseconds. It then drops the voltage and current and reduces power consumption to 1/9 of the original value to hold the valve in its energized mode, thereby reducing heat generation.

The CoolCube can remain under power indefinitely without being damaged. When power to it is cut, the valve immediately turns off as if the CoolCube were not in the system.
