Single Signal Generator PWM Pulse Frequency Duty Cycle Adjustable Module 1Hz-160Khz 4V-30V PWM Board Module 5mA-30mA brand new and high quality Features: With outer casing; LED display; High precision detection; 1-Channel PWM output; Support frequency adjustment; Support duty cycle adjustment; Support power-down memory function. PWM signal generator is a device that provides electrical signals at a variety of frequencies, square wave, and output levels. It is used as a signal source or excitation source for testing. Widely used in production practice and technology. Application: 1. Used as a square wave signal generator to generate square wave signals for development and use. 2. Used to generate a square wave signal that drives a stepper motor driver. 3. Generate adjustable pulses for use by the MCU. 4. Generate adjustable pulses to control the associated circuitry. Specification: Working voltage: for DC 4-30V Frequency range: 1Hz~160KHz Frequency accuracy: 2% Duty cycle range: 0.00%- Signal load capacity: output current 5~30mA Operating temperature: -20~70 Material: Plastic & metal Dimensions: 45.2x25.8x15mm/1.78x1.02x0.59inch LED display color: Red + blue Quantity: 1 Set Note: 1.Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid. 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you! Package includes: 1 Set Signal Generator ---------------- Instructions: The single PWM generator has only one set of PWM1 outputs and the frequency and duty cycle are independently adjustable. Two-way complementary PWM has two sets of PWM1 and PWM2 outputs. The two sets of frequencies have the same frequency and their duty cycles are complementary. Adjustable frequency 1-160KHz Duty cycle 0- adjustable Operating voltage: 4V~30V Frequency range: 1Hz~160KHz Frequency accuracy: 2% Signal load capacity: output current 5~30mA Output amplitude: The amplitude is equal to the working voltage. PWM output, can set the frequency, duty cycle The frequency is divided into four ranges, automatically switching: 1.XXX (no decimal point): 1Hz~999Hz, unit 1Hz 2.X.XX (decimal point in hundreds): Value is 1.00KHz to 9.99KHz in 0.01KHz 3.XX.X (decimal point in ten digits): The value is 10.0KHz~99.9KHz, the unit is 0.1KHz 4.X.X.X. (full decimal point): Value 100KHz~160KHz, unit 1KHz E.g: 100 represents 100Hz 1.00 means 1.00KHz 10.0 means 10KHz 1.0.0. Represents 100Khz Duty cycle 0~ adjustable Setting process: 1. Press the SET button. The frequency parameter flashes. Set the frequency with the UP or DOWN button. 2. Press the SET button. The duty cycle parameter flashes. Set the duty cycle by pressing the UP or DOWN keys. 3. Press the SET button to exit the setting 4. Long press the UP and DOWN keys to quickly increase or decrease 5. The data is automatically memorized and all setting parameters are saved when power is off.
