Adjustable PWM Pulse Frequency Duty Cycle Module with LCD Display (ZK - PP2K)

🛠️ Product Overview:
Introducing the Signal Generator PWM Module, model ZK-PP2K, designed for precision control in various electronic applications. This versatile module provides adjustable pulse-width modulation (PWM) and pulse outputs, making it ideal for driving loads such as LEDs, motors, and solenoid valves. With an intuitive LCD display and simple button controls, users can easily configure settings for a wide range of frequency and duty cycle adjustments.

🔍 Key Features:
1. Direct Load Driving: The module can directly drive various loads, including LEDs, motors, and solenoid valves, without additional circuitry.
2. Two Operational Modes: - PWM Mode: Allows continuous frequency and duty cycle settings. Outputs for the specified frequency and duty cycle indefinitely without a set limit for the number of cycles. - PULSE Mode: Users can adjust positive and negative pulse widths, set a delay for power-on start time, and specify a switch frequency, offering greater control and flexibility in applications.
3. User-Friendly Controls: Equipped with easy-to-use start and stop buttons for convenient signal management.
4. Wide Voltage Input: The module supports an input voltage range from 3.3V to 30V, catering to various project requirements and power supplies.
5. Clear LCD Display: Provides real-time visibility of frequency and duty cycle settings, facilitating ease of use.

🧩 Technical Specifications:
1. Operating Voltage: 3.3V to 30V (Ensure correct polarity to prevent damage).
2. Frequency Range: 1Hz to 150KHz with an accuracy of approximately 2% (ideal frequency for motor speed control typically 20KHz).
3. Duty Cycle Range: Supports 0% to 100% in 1% increments.
4. Pulse Count: Adjustable from 1 to 9999, or set to infinite (displayed as '----').
5. Output Delay: Ranges from 0.000 seconds to 9999 seconds, with a minimum adjustable interval of 1 millisecond.
6. Output Capacity: Can handle loads below 8A thanks to its MOS switch design.
7. Product Dimensions: Measures 79mm (L) x 43mm (W) x 30mm (H).
8. Weight: Lightweight at 42 grams.
9. Packaging: Each module is delivered in an anti-static bag for safe storage and transportation.

🔘 Functional Description:
The ZK-PP2K module operates in two modes for diverse applications. In the PWM mode, users can set the frequency and duty cycle using simple controls. The default settings upon factory initialization provide an output frequency of 1KHz and a 50% duty cycle. Switching to PULSE mode involves a straightforward button press, unveiling more options for pulse width and timing configurations.
Application probabilities are numerous; users can easily adjust LED brightness, control motor speeds, manage solenoid activation, or conduct switch fatigue tests. For instance, setting a PWM output can involve specifying a frequency of 20KHz with a 60% duty cycle, while PULSE mode can be configured to turn a device on for 0.6 seconds and off for 0.2 seconds, allowing for infinite looping actions.

💥 Applications:
The module is suitable across various domains, including:
- LED Control: Brightness adjustment through precise frequency and duty cycle settings.
- Motor Control: Efficient speed regulation for various motor types.
- Solenoid Actuation: Automated valve control and cyclical operations with adjustable parameters.
- Reliability Testing: Enables testing of switching fatigue and voltage drops on customer equipment to ascertain reliability.

🛠️ This robust Signal Generator PWM Module is an essential tool for anyone working on electronic projects requiring precise timing and output control, making it a valuable addition to your electronics toolkit.
