Product Description

MICRO PWM FAN CONTROLLER 

This MICRO PWM controller is the smallest and smartest CAN conroller available worldwide. With a footprint of just two Micro 280 style relays 

This controller can be order in several different configurations and will control a PWM style fan. 

PWM-CAN. This unit is configured for automatic variable fan speed operation. This unit will read the engine coolant temp and AC pressure info from the vehicle CAN BUS.  It will use this information to determine what speed to run the fan. The fan will run at a low idle speed when the module is powered on and the engine is running, as the engine temps or AC pressure increase the fans will be commanded to run at a higher percentage from 10-100%. 

PWM-CAN-INPUT. This unit is configured for automatic variable fan speed operation via the canbus. Also This unit can be equiped with up to 3 inputs. The inputs can be configured for "positive" or "negative" activation. 

PWM-INPUT. This unit is configured to use the inputs only. This configuration can be used where you do not have a canbus or the canbus is not supported. We can configure the inputs to activate via a "positive" or "negative" signal. You can choose up to three inputs. 

You can order the module with any combination of postiive or negative inputs. 

POSITIVE style activate when the input is over 3 volts

NEGATIVE style activate when the input is grounded

The extra inputs can be used to trigger the fan speeds for AC operation, manual overide or other applications. Special programing can be done uppon request, If you have a special request please email us before you make a purchase.  Email HERE if you have questions or want special programing
