A PWM signal generator is a device that provides electrical signals at different frequencies, square waves, and output levels. It is used as a signal source or excitation source for testing. Widely used in manufacturing practice and technology. Application:1. Used as a square wave generator to generate square wave signals for development and use.2. It is used to generate a square wave signal that drives the stepper motor driver.3. Generate adjustable pulses for use by MCU.4. Generate adjustable pulses to control the associated circuit. Specification: Working Voltage: DC 4-30V Frequency Range: 1Hz - 160KHz Frequency Accuracy: 2% Duty Cycle Range: 0.00%-100% Signal Carrying Capacity: Output Current 5 - 30mA Working Temperature: -20° - 70° Material: Plastic & Metal Dimensions: 45.2x25.8x1 5mm/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 bidding.2. Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!Package Included:1 Set Signal GeneratorInstructions:A single PWM generator has only one set of PWM1 outputs, and the frequency and duty cycle are independently adjustable. The bidirectional supplementary 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 1-160KHzDuty Cycle 0-100% AdjustableWorking Voltage: 4V - 30V Frequency Range: 1Hz - 160KHzFrequency Accuracy: 2% Signal Carrying Capacity: Output Current 5 - 30mAAoutput Voltage: The amplitude is equal to the working voltage. PWM output, can be set frequency, duty cycleThe frequency is divided into four ranges, automatically switching:1.XXX (without decimal point): 1Hz - 999Hz, unit 1Hz2.X.XX (decimal in hundreds): the value is from 1.00KHz to 9.99KHz in 0.01KHz3.X X.X (decimal in ten digits): the value is 10.0KHz - 99.9KHz, the unit is 0.1KHz4.X.X.X. (full decimal point): value 100KHz - 160KHz, unit 1KHzE.g:100 represents 100Hz1.00 means 1.00KHz10.0 means 10KHz1.0.0. Provides 100Khz Duty Cycle 0 - 100% Adjustable Process Setting:1. Press the SET button. The frequency parameter flashes. Set the frequency with the up button or the 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 setting4. Press and hold the up and down keys to quickly increase or decrease5. The data is automatically memorized and all setting parameters are saved when the power is turned off.
