ماژول ژنراتور موج PWM با قابلیت تنظیم فرکانس و Duty Cycle

 

Features:
Working voltage: 3.3~30V
Frequency range: Normal mode: 1Hz~150KHz And Precise mode: 1Hz~15KHz
Frequency accuracy: accuracy is about 2% in each range
Duty cycle range : 0.00%-100%
Duty cycle accuracy : 1% in Normal mode And 0.1% in Precise mode
Signal load capability: output current can be around 5~30mA
Output amplitude: PWM amplitude is equal to supply voltage
LCD display showing frequency and duty cycle
Ambient temperature: -20~+70

Instruction:
1.Connect to power supply
2.Press rotary switch for 10second to switch Normal mode and Precise mode
3.Short press rotary switch to set frequency and change value by rotating switch
4.Press rotary switch for 2 seconds to set the duty cycle
5.Keep press for 5second to lock set parameters
6.Test
7.Remove power and connect load to use module.

Communication standard:
9600 bps Data bits: 8
Stop bit: 1
Control digit: none
Flow control: none

1. Set frequency of PWM
"F101": Set the frequency to 101 HZ (001 to 999)
"F1.05": set frequency 1.05 KHZ (1.00 ~ 9.99)
"F10.5": Set the frequency to 10.5 KHZ (10.0 ~ 99.9)
"F1.0.5": Set the frequency of 105 KHZ (1.0.0 ~ 1.5.0)
Note: This mode, maximum frequency 15.0 KHz

2. Set PWM duty cycle
Normal Mode:
"DXXX": set PWM duty cycle for XXX; (001 ~ 100)
Like D050, set PWM duty cycle 50%
Slim Mode:
"DXX. X": set to PWM duty cycle XX. x; (0.1 ~ 100)
Like D20.8, set PWM duty cycle 20.8%

3. Read the set parameters
To send a "read" to read the string set parameters.
4. Modify Mode
"MODE0": Normal Mode
"MODU1": Fine Mode
Set successfully return: DOWN;
Setup failed return: FALL.

Applications:
1.is used as a square wave signal generator to generate square wave signals for experimental development.
2.is used to generate square wave signals that control motor drives.
3.generate adjustable pulse for MCU use;
4.generate adjustable pulses to control related circuits (PWM dimming and speed regulation applications).
