$445.00

Roboteq's VSX1850 is a high-current controller for Separate Excitation DC motors. The controller is composed of a unidirectional half-bridge capable of up to 500A for the motor's armature, and a 25A bidirectional power bridge for the motor's excitation (field).

The controller accepts commands received from a RC radio, Analog Joystick, wireless modem, or microcomputer to coordinate the armature and field bridge power so that the motor will move in a precisely controlled manner in the forward or reversed direction. The motor may be operated in open or closed loop speed mode. Using low-cost position sensors, it may also be set to operate as a heavy-duty position servos.

The controller's operation can be extensively automated and customized using Basic Language scripts. The controller can be configured, monitored and tuned in realtime using a Roboteq's free PC utility. The controller can also be reprogrammed in the field with the latest features by downloading new operating software from Roboteq.
