LCD Digital PWM Signal Generator pulse frequency duty cycle adjustable

1.PWM signal generator, square wave rectangular wave signal generator 2. Used to generate a square wave rectangular wave signal, which is supplied to a DC motor or a stepper motor driver; Stepper motor, servo motor, electric gripper, robot arm 3. Combine the driver to realize dimming, speed regulation, control solenoid valve, etc. However, it is not possible to directly drive loads such as electric lights, motors, and solenoid valves 1. Highlights: 1.1 Two modes can be selected: PWM mode - frequency (continuous), duty cycle.Note that the number of pulses cannot be set in this mode, and the pulse is always emitted; PULSE mode - positive pulse width time, negative pulse width time, delayed start time, and adjustable number of pulses. 1.2 With start-stop button, external switch can also be used to control output signal ON/OFF. 1.3 Wide voltage input 3.3-30V, with anti-reverse protection, 5.08mm terminal wiring 2. Technical parameters: - Working voltage: 3.3~30V, with anti-reverse protection - Frequency range: 1Hz~150KHz, accuracy about 1% - duty cycle range: 0-100%, 1% stepping - number of pulses: 1-9999, or infinite (display '----' stands for infinity) - delay output time: 0.000s-9999s, the minimum can be set 1ms - positive and negative pulse width length: 0.000s-9999s, the minimum can be set 1ms - signal loading capacity: less than 30mA - Output signal amplitude: amplitude is equal to the supply voltage - Product size: 79mm*43mm*30mm - Product Weight: 40g
