Description

ZK-4KX Buck Boost Converter 0.5–30V 4A with Display

The ZK-4KX Buck Boost Converter is a versatile, high-performance DC-DC converter capable of both step-up (boost) and step-down (buck) voltage regulation. Featuring an intuitive LCD display, it shows key operating parameters in real time — including input/output voltage, current, power, capacity, and run time. With precise CNC control knobs, users can easily adjust output voltage (0.5–30V) and limit current (0–4A), making it ideal for applications such as battery charging, power supply design, testing, and DIY electronics projects.

ZK-4-KX-008

Built for safety and reliability, the ZK-4KX includes multiple protection features such as input reverse polarity, overcurrent, overvoltage, overpower, and overtemperature protection, all with adjustable thresholds. The module’s efficient heat dissipation, aided by a thickened heatsink, ensures stable operation up to 50W with enhanced cooling. Compact yet powerful, this module offers excellent versatility for powering or testing various DC devices with precise control.
