XY-PWM1 signal generator module
PWM output can set frequency and duty cycle respectively.
Frequency is divided into four intervals:
- 1. XXX The smallest unit is 1Hz, and the value range is 1Hz ~ 999Hz; The minimum unit of
- 2. X.XX Is 0.01Khz, and the value range is 1.00Khz ~ 9.99Khz;
- 3. XX.X The smallest unit is 0.1Khz; and the range is 10.0KHz~99.9KHz.
- 4. X.X.X The smallest unit is 1Khz; and the range is 1KHz ~ 150KHz. E.g. frequency display: 100 indicates PWM output 100Hz pulse;1.01 represents the pulse of PWM output 1.01K. 54.1 represents the pulse of PWM output 54.1 KHz. 1.2.4 indicates the pulse of PWM output 124KHz. Duty cycle: 0 ~ 100%; All settings are saved by power down.
Parameter setting:
Module has four keys, used to set the frequency and duty cycle, can distinguish between short press (increase or decrease a unit) and long press (quickly increase or decrease). Set parameters save automatically and aren't lost with the power cut.
Scope of application:
- 1. Square wave signal generation for electrical experiments.
- 2. Square wave signals to control motor drives.
- 3. Adjustable pulse for MCU use;
- 4. Adjustable pulses to control related circuits (PWM dimming and motor speed control).
Specifications:
- Working voltage: 3.3 ~ 30V
- Frequency range: 1Hz ~ 150KHz
- Frequency accuracy: accuracy is about 2% in each range
- Signal load capability: output current can be around 5 ~ 30mA
- Output amplitude: PWM amplitude is equal to supply voltage
- Ambient temperature: -20~+70℃
- Dimensions: 3.7 x 4.3 x 7.8cm / 1.46 x 1.69 x 3.07 inch
- Color: Black
