If your Koolance pump has a 4-pin
Molex connector, you must use the
plug adapter included with your speed
controller.
The Koolance CTR-SPD1224 uses voltage
control to throttle speeds for 12VDC pumps or
fans. With a jumper setting, it will also step-up
and throttle voltage for 24VDC devices. CTRSPD1224 requires a 12VDC input.
Do not operate components at voltages which
exceed their specifications. Running a 12V-max
pump at 24V from the speed controller can
damage the pump.
To avoid damaging the speed controller,
do not connect devices which exceed the
Power In
(12VDC)
Power Out
(Pump, Fan, etc.)
controller’s maximum power rating (36W@12V,
50W@24V).
If your Koolance pump has a 3-pin power connector, plug it directly into the speed
controller’s “Power Out” connection. Connect the power supply’s 4-pin Molex plug
to the speed controller’s “Power In” connection.
