- ♥Product introduction: This series of products are PWM and pulse signal generators. There are PWM mode and pulse mode. Only one mode can be used at a time, but the two modes can be switched at any time.
- ♥Features: 1. Two modes can be selected: PWM mode - frequency (continuous), duty cycle. The number of pulses is not adjustable, and the waveform is continuously sent; PULSE pulse mode - positive pulse width time, negative pulse width time, delay start time, and the number of pulses are adjustable. 2. With the start and stop button (ZK-PP1K can be connected to an external switch to control the output signal ON/OFF). 3. Wide voltage input 3.3V-30V, with anti-reverse connection protection.
- ♥Product Specifications: 1. Working voltage: 3.3V~30V, with anti-reverse polarity protection 2. Frequency range: 1Hz~150KHz, the accuracy is about 1% 3. Duty cycle range: 0-100%, 1% step 4. Number of pulses: 1-9999, or infinite (display '----' means infinite) 5. Delay output time: 0.000s-9999s, the minimum can be set to 1ms 6. Positive and negative pulse width length: 0.000s-9999s, the minimum can be set to 1ms 7. Signal carrying capacity: ZK-PP1K: less than 30mA
- ♥Operation explanation: 1. There is an output waveform when powered on; 2. Waveform amplitude = power supply voltage; 3. When the number of output pulses reaches the set value, the output will be automatically stopped, and 'OUT' will disappear; 4. Press the ON key to control the presence or absence of the waveform, the disappearance of OUT means that there is no output waveform, and the output is 0; 5. Power on and restart or ON key to turn on the output, and recalculate the number of pulses;
- ♥Application scenarios: 1. PWM signal generator, square wave rectangular wave signal generator. 2. It is used to generate square wave and rectangular wave signals to control DC motor or stepper motor driver; it is used for servo motor, stepper motor, electric gripper, replace PLC pulse, etc. 3.ZK-PP1K can be matched with drivers to realize dimming, speed regulation, control solenoid valves, etc., but cannot directly drive loads such as electric light motor solenoid valves, etc.

FAQ:
Q: What is VFD, how it works?
A: How Do VFDs Work? The adjustable flow method changes the flow curve and drastically reduces power requirements. Variable frequency drives (VFDs) convert constant frequency and voltage input power to an adjustable frequency and voltage source for controlling the speed of alternating current (AC) induction motors.
Q: What is load frequency controller in a power system?
A: Load frequency control (or frequency control) is the system by which the frequency of the grid is kept or brought back to its nominal value after the demand-generation gap. The frequency control of the whole power system is done by generating units.
Q: Who is Control Freq?
A: Control Freq was started by Noel Sesto in 2007. Noel was born in London and moved to Perth, Australia with his family when he was 6 years old. He began working for a company called Bollinger Automation (which is still running today) from the age of 19, training as an Electrical Engineer.
Q: What is a RF controller?
A: RF receiver (also called rf controller) is used to connect with electrical devices, so the devices can be controlled by remote transmitter.
