To adjust the pulse width output of the PPPWM PWM Signal Generator Adapter, follow these steps:
1. Plug the PPPWM into the 4mm banana socket of the PP product that is being powered by 12V, and connect the grounding lug of the PPPWM to the PP product ground. Ensure that the grounding is reliable and there is no poor grounding.
2. Connect the positive terminal of the device you want to drive (e.g., a fan) to the PWM TIP output of the PPPWM. Connect the negative terminal to ground.
3. Press and hold the ROCK SWITCH of the PP product forward to power on the PPPWM. The PPPWM screen will light up.
4. Use the up or down button on the PPPWM to adjust the output pulse width. This will drive the connected device (e.g., fan) to rotate at different speeds.
5. The PPPWM can also display the power supply voltage. Press the Up and Down buttons simultaneously to switch between voltage display mode and pulse width display mode. Note that the pulse width cannot be adjusted in the voltage display mode.
Please refer to the provided user manual for additional safety precautions and technical specifications of the PPPWM PWM Signal Generator Adapter.
