RoboteQ ax2550HE High Efficiency 2-Channel Motor Controller
High-Efficiency version of the RoboteQ ax2550 2-Channel Controller.

$645.00

Roboteq's AX2550 controller and its AX2850 variant are 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.

Great product - great tech support.

I am using the AX2550HE in a 350+ pound "remote controlled cow" (two 1 Hp motors, mixed mode steering, 24V Lead Acid power). It has worked flawlessly. Setup was easy even w/o hookup to a PC (via front panel controls). This "HE" version barely even gets warm in my application (45 Amp motor current limits, slow acceleration limit). Tech support was great in helping with setup parameters, wiring, and operation - thanks to Cosma. Do comply with correct hookup to ensure your warranty remains valid (read the excellent manuals available on the Roboteq website).
