HIGH COUNTRY TEK - E-Fan System CONTROLLER, emc-1P & emc-1PL

These versions of the fan system controllers have been designed to interface with an e-Fan cooling systems and outputs a protected low level PWM signal that is scaled via the configurable settings, to represent the 0 to 100% fan speed demand.

These Controllers use the vehicle SAE J1939 temperature information to determine fan speed requirements and utilizes an easy to use PC based Graphical User Interface ( GUI ) to allow complete user configuration of the controller and system operation, including fan speed limiting, the reverse / purge / de-ice feature, data logging and system health monitoring.

Both units have an alarm output that can be used to interface with external systems, alerting the vehicle operator to a cooling issue that needs attention.

The controllers have an extended supply voltage and operating temperature range and are fully protected by flame resistant resin to ensure reliable operation under extreme environmental conditions.

All electrical connections are made through the industry standard IP67 12 way male Deutsch connector, with a 3 way SAE J1939 connector for vehicle interface and set-up via a 4 way female WeatherPack connector ( not shown for clarity ).
