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.
