CoolCube™
“hit and hold” circuit
Voltage “Step-down” Function
The compact CoolCube™ solenoid control modules provide an
easy way to achieve a “hit and hold” circuit independent of the
rated voltage.
When a CoolCube™ is connected between a solenoid valve
and a power supply, it delivers a pulse width modulated (PWM)
“step-down” function. It accepts a range of inputs from 12 to
36 VDC and passes the input on to energize the solenoid valve
with full power for 100ms. After 100ms, the CoolCube™ drops the
voltage and current to a level sufficient to hold the solenoid in
the energized position.
The benefits are less power consumption and lower heat
generation. The CoolCube™ can remain under power indefinitely
without being damaged. When the power to the CoolCube™
is cut, the valve is turned off immediately, as though the
CoolCube™ was not in the system.
Overdrive Function
The CoolCube™ enables an overdrive voltage to be placed on
a solenoid valve. This means that a solenoid valve rated for
12 VDC or 24 VDC can be energized with a voltage as high as
36 VDC. Since the CoolCube™ automatically drops the voltage
after 100ms, the solenoid will not be impaired in any way.
The benefits of this are:
•
Faster response time - the valve opening response time
can be decreased by up to 60%.
•
Increased pressure rating - the operating pressure rating
can be dramatically increased*.
•
Pinch valve tubing - allows the use of larger tubing
and / or custom tubing material*.
* Requires additional valve customization.
