Product Description

Roboteq’s AX1500 controller 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 controller's two channels can either be operated independently or mixed to set the direction and rotation of a vehicle by coordinating the motion on each side of the vehicle. The motors may be operated in open or closed loop speed mode. Using low-cost position sensors, they may also be set to operate as heavy-duty position servos.

Both the AX1500 and the AX1500BP can be ordered in Single Channel Configuration SC for a single motor and double power.

The controller can be reprogrammed in the field with the latest features by downloading new operating software from Roboteq.
