Model Code Instruction

In order to let customers select the required water pump more quickly and accurately, we have made some minor adjustments to the model suffix of BLDC PUMP.

We divided the original “A” into “PWM” and “VR”. “A” means that the speed can be adjusted. There are three ways to adjust the speed: PWM signal speed adjustment, 0-5V analog signal speed adjustment, and manual potentiometer speed adjustment.

In fact, we need to use two different control boards for these three speed adjustment methods. The first is a board designed specifically for PWM signals. The second is a board designed for analog signals and manual potentiometers.

Sorry for confusing you. If any further questions, please don’t hesitate to submit your message.
