Constant Temperature Controllers and Accessories

The FK-45 kit combines an eight foot cross-linked polyethylene insulated wiring loom, the high current VC1245 control unit with an integrated low mass radiator temperature sensor, along with all of the necessary hardware needed for installation in order to provide closed loop, variable speed control (0 - 100%) of a vast majority of available cooling fans. Built-in short circuit, over current, and over temperature protection, along with UL-94 potting and a 6000 series aluminum heat sink provide an extremely reliable control solution. It can be used for all known aftermarket fans and all of the Ford fans with the exception of the factory Ford F150 fans.

The FK-75 kit is identical to the FK45, with the exception of a larger heat sink, which allows for a higher continuous current of 75A and can be upgraded to an FK95 at the factory. It can be ordered with a 10 gauge loom (up to 65A continuous current) or an 8 gauge loom (up to 85A continuous current). A 6 gauge loom is available upon request

The FK-95 kit is identical to the FK75 kit, but uses a 260 Amp continuous current output transistor

The 65p35 kit combines both a fan and water pump controller in one package. The system, optimized for efficiency, starts the water pump at 35% power. As the engine warms to the set point, the water pump increases power to 100%, at the same time, the fan speed rises linearly to 35% power. Over the next three degrees, the fan power increases linearly to 100% power

The L101 indicator connects to the controller output and varies linearly from green to red as the controller power output increases

The TADJ module allows adjustment from inside the cab of +/- 20 degrees F

 

instructions

 

A splitting loom is available to control dual fans

 

 

    

In applications where a long run to the battery is required, as with a relocated battery, an eight foot extension and input filter is available

 

instructions

 

An alternative to running a separate set of wires to the relocated battery, the input filter allows connection of the control unit to the starter solenoid. It is also required to allow running the low-impedance Ford dual fans
