When over‑current protection is disabled on the PWM3.0 controller, 12AWG wiring harnesses may melt while running high‑power motors. For high‑power applications, we recommend using 10AWG wiring harness for better safety.

In addition, for high‑current operation of the PWM3.0 controller, if an external shifter is used, you need to select a high‑current‑rated shifter. This concern does not apply to the PWM3.0‑B module. The PWM3.0‑B has built‑in forward/reverse function; it only receives signal input, and no heavy current will pass through an external shifter.
Please see the video for PWM3.0 usage and setting instructions.
