Lcd Digital Pwm Signal Generator Pulse Frequency Duty Cycle Adjustable Square Wave
9 reviews

PWM signal generator, square wave rectangular wave signal generator
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
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

FEATURES:


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.
With start-stop button, external switch can also be used to control output signal ON/OFF.
Wide voltage input 3.3-30V, with anti-reverse protection, 5.08mm terminal wiring
