The CONEX-CC is a very compact and inexpensive driver for Newport’s low power DC servo motor driven devices. For out-of-the box control, the CONEX-CC is preconfigured and delivered with the motion device. Available actuator configurations include TRA and LTA Series actuators.

The linear amplifier of the CONEX-CC provides the optimum drive solution for low-power motors. Compared to other solutions relying on cheaper PWM amplifiers, the CONEX-CC delivers much smoother motion, with less electrical noise and significantly less motor heating.

The motors are powered through a 24 VDC power supply, model CONEX-PS. For added convenience, the power can be shared with up to 5 modules using the supplied CONEX-PS-CB power chain cable. CONEX DC-Servo Controller and Accessories
