The Ultimate Benchtop Companion for Engineers and Makers

Finding a reliable, compact, and accurate power supply for electronics testing can be challenging. The DC-DC Buck Boost Converter is engineered to eliminate the guesswork from your voltage regulation. Whether you are stepping up a 5V USB input to power a 12V CCTV camera or stepping down a 24V supply for delicate Arduino microcontrollers, this module delivers perfectly regulated power with zero hassle.

Precision Control at Your Fingertips

Say goodbye to tiny, fragile potentiometers. The ZK-4KX utilizes a high-quality rotary encoder that allows for fast, CNC-accurate adjustments. A quick spin dials in your exact voltage (down to 0.01V) and current (down to 0.001A) limits. The bright LCD screen provides real-time feedback on input/output voltage, current, power, capacity, and running time, giving you complete visibility into your circuit's performance.

Built for Stability and Safety

Power surges and accidental reverse connections can destroy hours of hard work. That is why this module is fortified with multiple software and hardware protection mechanisms. It features anti-reverse connection protection on the input and anti-reverse irrigation on the output—meaning you can charge batteries directly without needing an extra blocking diode. A built-in high-efficiency ferrosilicon aluminum inductor and a π (Pi) filter ensure the output ripple remains incredibly low, providing clean energy to sensitive electronic components.

Engineered for Heavy-Duty Performance

Need more power? While it runs silently at 35W (3A) under natural heat dissipation, the heavily upgraded thicker radiator fin allows you to push the module to 50W (4A) for demanding applications. It is the perfect blend of a compact form factor and heavy-duty performance, ideal for both enterprise prototyping and dedicated DIY enthusiasts.
