Short Product Description

Transform your workstation with the DC-DC Buck Boost Converter. Delivering precise, adjustable power from 0.5V to 30V with up to 4A output, this compact laboratory-grade module features a crystal-clear LCD and robust hardware protections. Whether you are prototyping STEM projects or repairing intricate electronics, get stable, reliable power backed by 20 years of industry expertise.

Key Features

  • CNC Rotary Precision: Adjust voltage (0.5-30V) and current (0-4A) rapidly and accurately using the intuitive rotary encoder, avoiding the frustration of tiny screw adjustments.
  • Comprehensive LCD Display: Monitor your exact power draw in real-time, with clear readouts for voltage, current, wattage, capacity (Ah), and operational time.
  • Battery Charging Ready: Built-in output anti-reverse irrigation eliminates the need for external diodes when charging batteries, streamlining your setup.
  • Ultra-Low Output Ripple: Features a high-efficiency π (Pi) filter and ferrosilicon aluminum inductor to provide clean, stable power for sensitive microprocessors and RF modules.
  • 7-Tier Intelligent Protection: Automatically shuts down to prevent damage from over-voltage, under-voltage, over-current, over-power, over-temperature (up to 110°C), and reverse polarity.
  • Enhanced Thermal Management: Equipped with a thickened heatsink, ensuring safe and stable operation even when pushed to its 50W maximum output.

Full Product Description

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.

FAQ Section

Q: Do I need to add a blocking diode to charge a 12V lead-acid battery?
A: No. The ZK-4KX features built-in anti-reverse irrigation at the output end. You can connect it directly to your battery for charging without worrying about reverse current damaging the module.

Q: What happens if my load draws more power than the module can handle?
A: The module is equipped with adjustable Over-Power Protection (OPP) and Over-Current Protection (OCP). If the load exceeds your set thresholds (default 50W / 4.1A), the module will safely cut the output to protect both the converter and your connected equipment.

Q: Can this module step up a 5V USB power bank to 12V?
A: Yes, this is a true buck-boost converter. It can take a 5V input and boost it to 12V. However, please note that at a 5V input, the maximum output power is limited to approximately 15W.
