ZK-5KX Buck-Boost Converter 0.6-36V 5A 80W CC CV LCD Module
ZK-5KX DC-DC Buck-Boost Converter — Precise Voltage & Current Control with LCD Display
The ZK-5KX Buck-Boost Converter is a versatile, high-efficiency power module designed for electronics enthusiasts, engineers, and DIY builders. Supporting both step-up (boost) and step-down (buck) conversion in a single compact unit, it delivers adjustable output from 0.6V to 36V at up to 5A / 80W — all with crystal-clear LCD readouts for voltage and current monitoring in real time. Made in Mainland China.
Key Features
- Buck-Boost Operation: Seamlessly steps voltage up or down — input 6–36V, output 0.6–36V.
- CC & CV Modes: Independent constant-current (CC) and constant-voltage (CV) control for charging, testing, and regulated power supply applications.
- High Efficiency: ~88% conversion efficiency at 120 kHz operating frequency minimizes heat and energy waste.
- LCD Display: Real-time readings with 0.01V voltage resolution and 0.001A current resolution for precise monitoring.
- Soft Start: Built-in soft-start function reduces inrush current stress on connected loads.

Frequently Asked Questions
Q: What is the difference between a buck converter and a boost converter, and does the ZK-5KX do both?
A: A buck converter steps voltage down, while a boost converter steps voltage up. The ZK-5KX is a buck-boost converter, meaning it can do both automatically — making it ideal for applications where the input voltage may be higher or lower than the desired output voltage.
Q: Can I use the ZK-5KX to charge lithium batteries?
A: Yes. The module's adjustable constant-current (CC) and constant-voltage (CV) modes make it well-suited for charging lithium-ion, LiFePO4, and lead-acid batteries. Set the desired charge voltage and current limit using the onboard controls, and monitor the process live via the LCD display.
Q: How do I set the output voltage and current on this module?
A: The ZK-5KX features dedicated adjustment controls for both voltage and current output. Simply use the onboard buttons or potentiometers to dial in your target values. The high-resolution LCD display shows voltage (0.01V) and current (0.001A) readings in real time so you can fine-tune with confidence.
Q: What protection features does the ZK-5KX include?
A: This module includes a comprehensive set of adjustable protections: input undervoltage, output overvoltage, output overcurrent, overpower, overtemperature, timeout, and super-capacity protection — plus input and output anti-reverse connection safeguards. All thresholds are user-configurable within specified ranges.
