is a powerful, low-cost solution for PWM signal generation, combining the flexibility of dual modes with a compact design suitable for both industrial and DIY electronic projects.
This is the module's default setting. In , the display shows a percentage (e.g., "50%"). In this mode, you can adjust two main parameters:
The ZK-PP2K has two primary modes of operation: and PULSE Mode .
Maximum 8A (capable of directly driving motors or LED strips). Pulse Count: Adjustable from 1 to 9999, or set to infinite ( 2. Dual Operating Modes You can switch between these two modes by long-pressing the button for 2 seconds. PWM Mode (Display shows "%") Used for continuous speed control or dimming. Frequency: Set the oscillation speed (e.g., 20KHz). Duty Cycle: Controls the "On" time vs. total period (e.g., 60%). Pulse Mode (No "%" on display) Used for precise control of motor steps or timed bursts. Positive Pulse Width ( Duration the signal is HIGH. Negative Pulse Width ( Duration the signal is LOW. Pulse Number: The exact number of pulses to send before stopping. Delay Start: Sets a timer before the pulse sequence begins. 3. Button Functions & Settings ON/OFF Button:
The screen shows frequency (Hz) and duty cycle (%). Zk-pp2k Manual
: Ideal for dimming, speed regulation, and electromagnetic valves. PULSE Mode : The screen does not display "%".
Kael holstered the weapon. He placed a credit chip on the table, double the agreed amount. "For the manual. You can keep the file. I have a feeling you’ll be seeing more of these."
Verify the ON/OFF LED indicator is illuminated red.
PWM mode generates a continuous square wave. It is primarily used for speed control, dimming, and frequency generation. is a powerful, low-cost solution for PWM signal
PULSE mode allows precise control over timing, delays, and a fixed count of pulse cycles.
The is a highly versatile, intelligent constant current, constant voltage (CC/CV) buck power supply module. Known for its affordability and precision, it’s a favorite among hobbyists, electronics engineers, and battery enthusiasts for projects ranging from driving high-power LEDs to charging lithium-ion batteries. However, due to its multifunction interface and complex calibration requirements, many users find themselves searching for a clear, comprehensive Zk-pp2k Manual .
Short-press the encoder knob to cycle through parameters until flashes. Turn the knob to set it to 5.000 .
Set to PWM mode (1KHz-20KHz), adjust DUTY for brightness. In this mode, you can adjust two main
The ZK-PP2K is excellent for high-power LEDs (e.g., 100W COB LED).
Use Pulse Mode to move motors precise distances.
"The harmonic balancer?" Kael asked.
DC 3.3V - 30V (with anti-reverse connection protection) Frequency Range: 1Hz - 150KHz (Accuracy ≈ 1%) Duty Cycle Range: 0 - 100%, 1% stepping Pulse Number: 1 - 9999 or infinite ( ---- ) Delay Output Time: 0.000s - 9999s (minimum 1ms) Pulse Width Length: 0.000s - 9999s (minimum 1ms)
