Signal Generator PWM Pulse Frequency Duty Cycle Adjustable Module With LCD Display and Case 1Hz-150Khz 3.3V-30V

Features:; - Support Serial operation- Wide frequency range, high precision- LCD can display frequency and duty datio, Easy to oprate- Output of three-channel PWM at the same time- Adjustable Frequency, 3-channel frequency output consistent, duty ratio can be independently adjusted, suitable for most occasions;
Specifications:; 1. Operating voltage 3.3 ~30V; 2. Frequency range1Hz~150KHz; 3.
Frequency accuracy: In each range of accuracy is about 2%4.
Signal load capacity: Output current can be around 5~30ma5.
Output amplitude: PWM amplitude and supply voltage equal; 6.
Ambient temperature: -20~+70°7.
Size: 5.5 x 3.8 cm/ 2.17 x 1.50 inch;
Overview:; 1. Module has 4 independent keys, to set the frequency and duty ratio, support short press (increase or decrease a unit) and long press (fast increase or decrease), very simple, set the parameters automatically save, power loss. 2. 3-Way duty ratio button can be pressed at the same time, real-time adjustment, liquid crystal display is the last pressed button duty ratio, real-time is very strong, can be as a simple several road duty ratio scan.;
Parameter Settings:; Three-channel PWM; is outputted, wide frequency range and the duty ratio can be adjusted independentlyFrequency is divided into four areas, automatic
switching: 1.
XXX (No decimal point): 1HZ Stepping Unit, Range: 1Hz~999Hz; 2. X.
XX (The decimal is in hundreds place): 0.01KHZ Stepping Unit, Range: 1.00K hz~ 9.99K hz; 3. X.
XX (The decimal is in the tens place): 0.1KHZ Stepping Unit, Range: 10.0K hz~ 99.9K hz; 4. X. X.
X (The decimal is in the ones place): 1KHZ Stepping Unit, Range: 1Khz~150Khz; e. g.,
frequency display: 100 represent the pulse of 100Hz; 1.01 represent the pulse of 1.01KH z;; 54.1 represent the pulse of 54.1KH z 1.2. 4 represent the pulse of 124HzThe value range of dutyfactor: 0~100%, 100% is represented by A0%. All parameters setted up can be automatically saved in case of power cut.;
Application:; 1. as square wave signal generator to generate square wave signal for experiment development and use2. to generate a square wave signal to control the motor driver; 3. Generating adjustable pulses for MCU use; 4. Generate adjustable pulse, control related circuit (PWM dimming speed and other applications).;
