Davies Craig Variable Speed EWP/Fan Controller, Brushless, Sensor Type 1/8'' NPT

  

4 Wheels - Road Tuning. Davies Craig Variable Speed EWP/Fan Controller, Brushless, Sensor Type 1/8'' NPT.

The Davies Craig Variable Speed EWP / Fan Controller provides precise control over your car's cooling system to help maintain stable engine temperatures, improve cooling efficiency and reduce the risk of overheating under demanding conditions. It uses dual isolated output channels, configurable temperature set points, PWM control compatibility for brushless applications and programmable shutdown cooling functions to independently manage electric water pumps and single or dual fans with high accuracy. The following features explain how the controller manages cooling performance and system protection. Two independently controlled output channels allow you to operate any combination of single or dual electric water pumps and fans with separate settings for each channel, giving you accurate control over coolant temperatures and airflow management across different areas of the cooling system.

Brushed motor versions feature 2 x 40A fully isolated channels which support high current electric water pumps or multiple fans per channel, allowing you to manage demanding cooling setups provided the total current draw does not exceed 40A per output. Brushless motor versions use dual PWM signal channels with up to 5A combined PWM signal capacity, enabling stable and accurate speed control of modern brushless pumps and fans for smoother operation and reduced electrical load. Separate operating modes and temperature set points can be assigned to each output channel, allowing you to tailor fan and pump behaviour to suit different cooling requirements within the same vehicle. Support for both 12V and 24V electrical systems provides installation flexibility across a wide range of cooling system layouts and electrical configurations. Programmable shutdown time and temperature settings allow the pumps and fans to continue operating after ignition off, helping reduce engine heat soak and localised hot spots which can affect reliability and component life.

Dedicated manual override control for each channel allows you to permanently switch outputs on or off when required, providing direct control during testing, setup or specific operating conditions. In the event of a temperature sensor failure the controller automatically switches all channels to full speed operation, helping protect the engine and cooling system against overheating. The supplied temperature probe and thermal sensor provide multiple installation methods including radiator fins, thermostat housings, engine blocks, radiator tanks or top radiator hoses, allowing you to position sensors where temperature monitoring is most effective for your cooling layout. Thermal sensor options with either 1/8" NPT or 1/4" NPT threads provide compatibility with a wide range of coolant system ports and fittings for easier installation. User configurable temperature difference and fan start speed settings allow you to control how quickly fan speed increases relative to coolant temperature, helping stabilise operating temperatures and reduce unnecessary fan operation. Adjustable temperature offset settings allow sensor calibration corrections to improve monitoring accuracy and maintain more consistent cooling control. Integrated factory reset functionality restores all parameters to default settings, allowing you to quickly recover baseline settings during troubleshooting or system changes.

Maintaining stable coolant temperatures during sustained high engine loads helps reduce the risk of overheating, heat soak and inconsistent cooling performance within your car's cooling system. The Davies Craig Variable Speed EWP / Fan Controller allows you to independently manage electric water pump speed, single or dual fan operation and fan activation temperatures so coolant flow and airflow can be adjusted accurately to suit changing operating conditions. Programmable post shutdown cooling keeps coolant circulating after the engine is switched off which helps control retained heat around critical engine components.

Independent channel control and adjustable ramp settings also allow you to fine tune how quickly fans and pumps respond to temperature changes for more consistent thermal management across the entire system. The Davies Craig Variable Speed EWP / Fan Controller provides the level of cooling system control needed to manage electric pumps and fans with accurate temperature regulation, flexible configuration and built in protection functions. Waterproof IP67 construction, independent channel programming and automatic fail-safe operation provide reliable cooling system management for demanding vehicle applications where stable operating temperatures are critical.
