Manual — Zk-pp2k

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 .

The first line on the screen read like an invocation: "Zk-pp2k — zero-knowledge proof protocol, phase two, keyring." It was technical and poetic at once, as if the device itself had chosen words to hide a secret. Mara read on.

Displays real-time parameters with clean, backlit readability.

The ZK-PP2K is a digitally controlled . This means the output voltage must always be lower than the input voltage. It features a rotary encoder for navigation and a 0.96-inch OLED display. Zk-pp2k Manual

DC 3.3V to 30V (with anti-reverse protection) Frequency Range: 1Hz to 150KHz

Turn the encoder knob to adjust the frequency value. Short press the encoder to move the decimal point (adjusting the multiplier range). The is a highly versatile, intelligent constant current,

The ZK-PP2K operates in two primary modes. Long-press the button for 2 seconds to toggle between them. 1. PWM Mode (Display shows "%")

The unit balances compact physical dimensions with high-precision digital control. Specification Value DC 3.3V – 30V (with anti-reverse protection) Output Current 8A Maximum (Continuous lower, dependent on cooling) Maximum Power Frequency Range 1Hz – 150KHz Frequency Accuracy Duty Cycle Range 0.00% – 100% (1% steps) Pulse Number Count 1 – 9999, or Infinite ( ---- ) Delay / Pulse Width Time 0.000s – 9999s (Minimum step 1ms) Output Amplitude Identical to input voltage supply Physical Dimensions 79mm × 43mm × 26mm (Standard panel mount) Terminal Layout and Connection Guide

Most small to mid-sized DC motors operate efficiently at a frequency of 20KHz to minimize audible coil whine. PWM Mode (Ensure % is displayed). The first line on the screen read like

The is a highly versatile, dual-mode electronic module capable of generating square-wave signals and directly driving loads up to 8A . Operating within a flexible 3.3V to 30V DC range, it functions as both a laboratory signal source and an inline controller for high-power devices like DC motors, LED dimmers, and solenoid valves.
