Features: LCD display the frequency and duty cycle, and uses a digital encoder to set the frequency and duty cycle. Digital adjustment is convenient and fast, with high precision and high reliability. Dual mode, 0.1% duty cycle step in fine mode. Using 2 original low internal resistance MOS tubes and pre-drivers, the performance is better and more stable, and it supports high current and high frequency. The upper and lower limits of the working frequency and duty cycle can be set, which is convenient for users to operate and use according to the working characteristics of their own motors or LEDs. Equipped with start and stop button, which is convenient and quick; with for key lock function, after the for key is locked, the frequency and duty cycle cannot be modified to prevent misoperation. Support A1, A2 level output, can cooperate with special motor drive to realize motor forward and reverse rotation and braking functions. It is highly scalable. After connecting our WiFi module, we can remotely control the forward and reverse rotation and braking functions of the motor through the mobile phone APP.
