Motor Driver

Our solid-state DC Motor Driver is a highly-ruggedized control platform for variable-speed DC motor control. With high-current, factory bridgeable outputs, it can be used to control either four 30A DC motors (45A peak), two 60A DC motors (90A peak), single 120A motor (180A peak), eight (30A) proportional or on/off outputs suitable for hydraulic valves and other industrial equipment. In addition to the motor control outputs, CANbus via J1939, built in or external WiFi, built in 2.4 GHz or 900 MHz RF modules can be on board as well as up to eight analog inputs.


Where we think the motor driver really shines is that it can be built with Kar-Tech’s wireless control modules on board, to directly accept control inputs from almost any of Kar-Tech’s wireless radio transmitters. The electronics are housed in a custom anodized aluminum chassis designed to rapidly dissipate heat, and the unit is totally encapsulated for the ultimate in shock, vibration, and all-weather resistance.


Serial, CANbus via SAE-J1939, RF: 900mhz or 2.4GHz

Analog Inputs
Up to 10 analog inputs(0-5v or 4-20mA)

Standard Outputs
Configurable to drive up to 4 motors bidirectionally. Outputs can be bridged to drive higher currency loads, or can be configured as standard current regulated outputs for hydraulic values.

Operation Temperature
-40° to +85° C


Made by AXL wire, AWA varies with application & current requirements
