2 uds/1 unidad de señal PWM a voltaje 0-100% a 0-5V/0-10V salida 22Hz-20kHz 3,3 V-24V módulo de placa de conversión de señal analógica Digital

Version changes:

1. Changed the output range selection configuration (changed from jumper cap to strip line pad)

2. Default 0V-10V output

1. Module introduction:

This PWM to voltage module can convert PWM with 0%-100% duty cycle into 0V-5V or

or 0V-10V voltage output, the default voltage output is 0V-10V.

The module can change the output voltage range by soldering the jumper pad. The default module output

The range is 0V-10V. When the jumper pad is soldered, the output range of the module is: 0V-5V.

This module can be quickly implemented in conjunction with motors/LEDs and other driver boards that can be controlled through analog signals.

Functions such as motor speed regulation/light brightness adjustment.

2. Parameter introduction:

Low level is 0V)

Input signal frequency: 22Hz - 20kHz

Output level: 0V - 5V / 0V - 10V

Output allowable error: ±1.2% (22Hz - 20kHz)

Whether to bring isolation: No

Module size: 33mm * 33mm

3. Pin description:

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

GND: module power supply, signal, output negative pole

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

OUT: Positive output voltage, output 0V - 5V or 0V - 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 if the duty cycle is less than 10%, the output may have problems, so please ensure that the input

The PWM frequency is greater than 22Hz, or the duty cycle is greater than 10%.

The higher the input PWM frequency of the module, the output voltage error will be larger compared to the lower frequency.

Parameters are used within allowable tolerances and follow product parameter tolerances. After testing, the input PWM frequency is at

The output accuracy is higher at 2kHz-8kHz

After version V1.1, the module is equipped with KF301 terminals and 2.54MM straight pins and curved pins.

Users can weld different terminal blocks according to their own needs. The factory default is not to weld.

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
