Enables instrument designers to place an overdrive voltage on a solenoid valve, which can decrease valve response time, increase operating pressure, and allow the use of larger tubing in pinch valves
The newly designed CoolCube solenoid control module produced by Bio-Chem Valve enables OEM instrument designers to place an overdrive voltage on a solenoid valve, which can decrease valve response time, increase operating pressure, and allow the use of larger tubing in pinch valves.
It also provides a 'hit and hold' circuit without producing excessive, coil-generated heat, or consuming excessive power.
The CoolCube automatically drops the voltage to 1/3 of the input voltage after 110ms permitting an overdrive voltage on a solenoid valve without any impairment.
This means, for example, that a solenoid valve rated for 12VDC can be energised with a voltage of 24VDC.
As a result, with some valve adjustments, a valve's response time can be decreased by up to 60%, operating pressure and valve flow can be raised, and valve stroke can be increased to permit use of larger tubing with the same basic pinch valve design.
When installed between the valve and power supply the compact CoolCube can also provide an innovative power step-down.
It allows a solenoid to be energised with full power for 110 milliseconds then drops voltage and current to just enough power to keep the solenoid energised. This minimises power consumption and heat generation.
When power to the CoolCube is cut, the valve immediately turns off, as if the CoolCube were not in the system.
The CoolCube measures only 25.5mm x 16.5mm x 4mm.
It accepts either a 12V or 24VDC current.
