EMC Series

The EMC is a compact single e-fan bank controller designed to control multiple variable speed brushless fans. The controller provides low current varying PWM signal to the fans based upon the command inputs. Uniquely designed for multiple uses and ranging levels of complexity. The EMC is easily integrated into simple air handling applications or more complex Tier IV and Tier V cooling systems due to the configurable thermistor and diagnostic input options in addition to SAE J1939 communication with custom message capabilities. The uniquely hardened package makes this a rugged option for the Mobile and On-Highway industries. It also is ideal for refrigeration systems, aftermarket heat exchanger packages, compartment cooling, performance vehicles, air handling systems, and isolated cooling needs like; charge air, engine bay ventilation, transmission or hydraulic oil cooling.

The EMC’s unique PID Set Point feature automatically adjusts the fan speed based upon the user set temperature while prioritizing the multiple thermistor inputs and J1939 messages. For greater performance requirements the OEM can adjust the cooling response by adjusting the PID closed loop settings. The EMC is also unique such that it can be configured through the Graphical User Interface (GUI) to control any combination of Active High and Active Low e-Fans making this a single solution for multiple fan types.

The simple and easy-to-use GUI enables the user to perform simple or complex actions based upon the configurable inputs. The GUI is password protected for OEM manufacturers in order to prevent tampering of the pre-tested and qualified OEM configurations. The GUI is designed to have a standard diagnostic dashboard for service technicians that enable access to non-critical functions while obtaining necessary functional information and recording data for troubleshooting or performance monitoring.

The EMC is a single economical hardware solution that provides a great deal of functionality making this an affordable solution for the simplest requirements to the most stringent and complex demands.
