1. 서론
The ZK-PP4K is a versatile PWM (Pulse Width Modulation) pulse generator designed for controlling LED lighting, motor speed, and other applications requiring precise dimming or speed regulation. It features a digital LCD display for clear parameter viewing and supports slow start and slow stop functions for smooth operation. This manual provides essential information for the proper setup, operation, and maintenance of your ZK-PP4K device.
2. 제품 오버view
The ZK-PP4K unit consists of a main control module with an LCD display, a rotary encoder for adjustments, and terminal blocks for electrical connections.

그림 2.2: Dimensions of the ZK-PP4K PWM Pulse Generator. The unit measures approximately 79mm in length, 43mm in width, and 26mm in height.
3. 설정 및 배선
Proper wiring is crucial for safe and effective operation. Ensure the device is powered off before making any connections.
3.1 터미널 연결

그림 3.1: 뒤쪽 view of the ZK-PP4K showing the terminal block. From left to right, the terminals are labeled GND, PWM, V-, and V+.
- 브이+: Positive power input (DC).
- V-: Negative power input (DC).
- PWM : PWM signal output to the load.
- GND : Ground connection for the PWM signal.
3.2 전원 공급 요구 사항
Connect a stable DC power supply to the V+ and V- terminals. Refer to the specifications section for the acceptable voltage range. Ensure correct polarity to prevent damage to the device.
3.3 부하 연결
Connect your load (e.g., LED strip, DC motor) to the PWM and GND terminals. The PWM output provides the modulated signal to control the connected device.
4. 사용 설명서
Once wired, power on the device. The LCD will illuminate, displaying the current frequency and duty cycle settings.
4.1 Adjusting Frequency and Duty Cycle
- 로터리 인코더: Rotate the knob to adjust the displayed parameter.
- 짧은 보도: A short press of the rotary encoder button will switch between adjusting the frequency and the duty cycle. The active parameter will typically blink or be highlighted.
- 길게 누르기 : A long press of the rotary encoder button may enter or exit advanced settings or save current settings, depending on the firmware version. Refer to the on-screen prompts.
4.2 Slow Start and Slow Stop Functions
The ZK-PP4K supports slow start and slow stop features, which allow the PWM output to gradually increase or decrease to the set value. This is particularly useful for applications requiring smooth transitions, such as dimming LEDs or gradually accelerating motors. These functions are typically configured within the advanced settings menu, accessible via a long press of the rotary encoder.
5. 유지관리
The ZK-PP4K is designed for reliable operation with minimal maintenance.
- 청소: 부드럽고 마른 천으로 기기를 닦으세요. 액체 세척제나 용제는 사용하지 마세요.
- 환경: 기기는 깨끗하고 건조한 환경에서 작동시키고, 과도한 먼지, 습기 및 극한 온도에 노출시키지 마십시오.
- 사이: 모든 전기 연결부가 안전하게 연결되어 있는지 주기적으로 점검하십시오.
6. 문제 해결
If you encounter issues with your ZK-PP4K, consider the following common problems and solutions:
- 디스플레이 없음/전원 없음:
- Check power supply connections (V+, V-).
- 전원 공급 볼륨을 확인하세요tage는 지정된 범위 내에 있습니다.
- 극성이 올바른지 확인하십시오.
- No PWM Output:
- Check connections to the load (PWM, GND).
- Verify that the duty cycle is set to a non-zero value.
- 기기의 전원이 올바르게 공급되고 있는지 확인하십시오.
- Incorrect Output/Unstable Operation:
- Ensure the load is compatible with the PWM output specifications.
- 연결 상태가 느슨한지 또는 간섭이 있는지 확인하십시오.
- Reset the device to factory settings if possible (refer to advanced settings).
