RoboteQ ax3500 Single-Channel Motor Controller
Part# RTQ-AX3500SC

RoboteqŐs AX3500 is designed to convert commands received from a R/C radio, Analog Joystick, wireless modem, or microcomputer into high voltage and high current output for driving one or two DC motors. Designed for maximal ease-of-installation, it is delivered with all necessary cables and hardware and is ready to use in minutes.

The Single Channel controllers are identical to the Dual Channel except that the output transistors of both channels are perfectly synchronized and thus allow the motor output leads to be wired in parallel and thus drive twice the amps into a single load.

The AX3500 version is equipped with quadrature optical encoders inputs for precision speed or position operation. Numerous safety features are incorporated into the controller to ensure reliable and safe operation.
