ZK-PP1K Signal Generator PWM Pulse Generator Square and Rectangular Waves Stepper Motor Lap Driver Delay Time Pulse Width Frequency Duty Cycle Adjustm The ZK-PP1K signal generator is a versatile signal generator. It can generate PWM pulses, square waves, and rectangular waves, which are widely used in the drive control of stepper motors. It has the function of adjusting the number of pulses, delay time, pulse width, frequency, and duty cycle. It can be precisely adjusted according to the actual needs. It is a powerful, easy-to-use, and stable signal generating device, which is perfect for stepper motor drive control. Features: Versatile Design: It can generate PWM pulses, square waves, and rectangular waves, which are widely used in stepper motor drive control. Digital LCD Display: LCD screen display with large font for easy data reading, you can see the data clearly at a glance. Multiple Display Modes Switching: It has three working modes, including PWM mode, pulse mode, and pulse mode setting, which can be switched by the user as needed. PWM mode interface displays frequency and duty cycle; pulse mode interface displays positive and negative pulse width time; pulse mode setting interface can display power-on delay time and number of pulses. Practical Scenarios: Used to generate square waves and rectangular waves signals to control direct current motors or stepper motor drivers; used for servo motors, stepper motors, electric grippers, replacing PLC pulses, and more. Wide Applications: Matching driver to realize dimming, speed control, control solenoid valves, etc., but can not directly drive the lamp motor solenoid valves and other loads.
