Description

The jumper cap must not be inserted at 5V and GND.

Note:

The power supply of the module is strictly controlled within 12V. When the input PWM frequency is less than 22Hz and the duty cycle is less than 10%, the output may have problems. Therefore, when using, please ensure that the input PWM frequency is greater than 22Hz or the duty cycle is greater than 10%.

The higher the input PWM frequency of the module is, the greater the output voltage error is compared with the low frequency, and the allowable error of the product parameters shall be followed when using within the allowable parameters. The output accuracy of the tested input PWM frequency is high under the condition of 2kHz - 8kHz

0V - 10V gear, input 70% duty cycle to test the duty cycle of 20K, 10K and 1K frequency respectively

0V - 10V gear, input 20% duty cycle to test the duty cycle of 20K, 10K and 1K frequency respectively

0V - 5V gear, input 90% duty cycle to test the duty cycle of 20K, 10K and 1K frequency respectively

0V - 5V gear, input 30% duty cycle to test the duty cycle of 20K, 10K and 1K frequency respectively
