Working voltage: DC5V~30V, input anti-reverse protection

Rated current: 5A Maximum current 15A

Maximum power: 150W

Working frequency: 1KHz-99KHz adjustable, 1KHz step, the default frequency is 20KHz, the accuracy is about 1%

Duty cycle: 0-100%, 1% step

Instructions for use:

1. In the default interface: (The default display is the duty cycle)

Short press--switch motor start and stop

Rotate counterclockwise-the duty cycle decreases

Turn clockwise to increase the duty cycle

Long press one-enter the setting interface

2. Under the setting interface:

Short press one-to select the setting parameter, and the setting parameter can be switched between the lower limit of the duty cycle, the upper limit of the duty cycle and the working frequency. The lower limit of the duty cycle is displayed as "_" + two digits, the upper limit of the duty cycle is displayed as "H" + two digits or "100", and the operating frequency is displayed as "F" + two digits.

Rotate counterclockwise one-the corresponding setting parameter decreases

Rotate clockwise one by one the corresponding setting parameters increase

Long press to exit the setting interface

3. STOP port on the back

An external switch button or 3.3V level can be connected. When the button is closed or the 3.3V level is pulled down, the start/stop state of the motor can be switched.
