VBus^®-Accessories

Interface adapter VBus^®/PWM

The VBus^® / PWM interface adapter enables the speed control of two high-efficiency pumps even without an integrated PWM-output on the system`s controller. The adapter is installed between the VBus^® output of the controller and the PWM-input of the high-efficiency pump, where it transforms the VBus^® data packets into a 0-10 V or a PWM signal.
