To understand the module's capabilities, here is a breakdown of its core technical specifications:
Connect the power supply. The device will boot up, displaying a loading screen, and eventually land on the main interface showing the date, time, and "Verify" prompt.
To use the Push/Pull (PP2K) functionality, the device must be connected to your network. Zk-pp2k Manual
Note: This device utilizes a low-side N-channel MOS switch. The OUT+ terminal connects directly to VIN+. The OUT- terminal switches to VIN- to complete the circuit. 🕹️ Interface and Button Operations
This comprehensive manual provides technical specifications, wiring configurations, and step-by-step programming blueprints to help users maximize the utility of the module. Technical Specifications and Pinout
The ZK-PP2K distinguishes itself from standard signal generators by incorporating a high-current MOS switch-tube output. This eliminates the need for an external relay or transistor buffer when driving heavy inductive or resistive loads. Note: This device utilizes a low-side N-channel MOS switch
: Ensure your input voltage matches the requirements of your load (e.g., use a 12V supply for a 12V motor).
Ideal for standard DC motor speed control and LED dimming. 2. PULSE Mode (Display lacks "%")
features a clear LCD screen displaying Frequency (F), Duty Cycle (D), and Pulse Count (P). Output signal terminal. V+ / V-: Power supply input (3.3V - 30V). Duty Cycle (D)
Example C: Delayed Equipment Stress Testing (5s Delay, 100 Cycles)
The most common cause of failure is incorrect wiring. The ZK-PP2K has two distinct sides: and Output . Do not reverse them.
Automatically preserves all fine-tuned variables and mode selections when power is disconnected.
According to product listings on AliExpress , the key specs include: : DC 3.3V - 30V. Frequency Range : 1Hz - 150KHz (Accuracy ~2%). Duty Cycle : 0.00% - 100%. Output Current : Rated up to 8A (Direct load drive).
