Zk-5kx Manual Jun 2026

Short-press U/I to return to the active main terminal display. Advanced Menu: Threshold Protections & Startup States

Illuminates when the module enters constant current mode (e.g., when charging a battery or driving high-power LEDs). ON: Illuminates when the output terminals are live. Wiring Terminals

: Use the constant current mode to safely power LEDs without a resistor.

The ZK-5KX features a digital encoder (the knob) and two buttons: (Upper) and SET (Lower).

If you plan on pulling more than 4A or 80W consistently, add a small 12V fan or a larger heatsink to the back of the board. Zk-5kx Manual

| Specification | Rating / Range | | :--- | :--- | | | 6.0V - 36V DC | | Output Voltage | 0.6V - 36V DC, adjustable | | Output Current | 0 - 5A, adjustable, constant current (CC) feature | | Output Power | 80W maximum, buck and boost mode | | Display Resolution | Voltage: 0.01V / Current: 0.001A | | Conversion Efficiency | Approximately 88% | | Switching Frequency | 120 kHz | | Operating Temperature | -40°C to +85°C | | Protection Features | Input reverse polarity, output backflow prevention, over-voltage, over-current, over-power, over-temperature, under-voltage, output timeout, output over-capacity | | Dimensions (LxWxH) | 79mm x 43mm x 48mm (3.11in x 1.69in x 1.89in) | | Weight | Approx. 119g (without packaging)|

Long press the rotary encoder to toggle between these states. Long press to exit. 3. Setting Protection Thresholds Long press U/I to enter the parameter interface.

Approximately 88% at a working frequency of 120kHz. Operational Controls

The module defaults to Constant Voltage (CV) mode, meaning it will try to maintain a constant output voltage. To adjust it: Short-press U/I to return to the active main

Set maximum capacity or time limits (useful for timed battery charging). To save and exit: Long press "SET" again. 5. Safety Features & Protections The ZK-5KX is equipped with several software protections:

Output ceiling protection (Adjustment range: 0.5V–37V, default 36V). Over-Current Protection

Knowing these parameters allows me to calculate your optimal , OCP , and cooling requirements. Share public link

The core function of the Zk-5kx is user identity management. The manual divides enrollment into three distinct methods. Wiring Terminals : Use the constant current mode

The Zk-5kx manual is designed to be a comprehensive guide that provides users with everything they need to know to get the most out of their device. Some of the key features of the manual include:

Includes under-voltage (LUP), over-voltage (OUP), over-current (OCP), over-power (OPP), and over-temperature (OTP) protections. Operating Instructions 1. Setting Output Voltage & Current

Input threshold protection (Adjustment range: 4.8V–30V, default 5.8V). Unit cuts output if input sags below this. Over-Voltage Protection
