Convertitore di frequenza di tensione da 22Hz-20kHz a 0-5/0-10V modulo di conversione del segnale analogico digitale modulo da segnale a tensione PWM 0-100%

The PWM to voltage module can convert 0% – 100% duty cycle PWM into 0V-5V or 0V-10V voltage output.The module can change the range of output voltage by selecting the position of jumper cap. The jumper cap is inserted at the GND end, that is, the SET and GND are shorted, and the output range is 0V-5V; When the jumper cap is inserted into the 5V

end, the SET and 5V are shorted, and the output range is 0V-10V.

This module can cooperate with the motor/LED and other drive boards that can becontrolled by analog signals to quickly realize motor speed regulation/light brightness

adjustment and other functions.

Pin description:

VIN: positive pole of module power supply, power supply range 3.3V- 12V

GND: module power supply, signal, output cathode

PWM: PWM input, frequency 22Hz – 20kHz amplitude+3.3V -+24V

OUT: output voltage positive pole, output0V – 5V or0V- 10V

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
