Product details

Compact, adjustable power with clear readouts

The Seloky LM2596 DC-DC buck converter modules deliver reliable voltage regulation in a compact package. Each unit features a bright LED voltmeter display for quick voltage checks, helping you monitor output while you tune settings. The display offers an accuracy of about ±0.1V, giving you a useful reference point as you work on prototypes and builds. If you need to simplify wiring, this device also supports solderless connections through terminal blocks.

What the module can do

  • Inputs range from 4.0V to 40V and outputs can be adjusted from 1.25V to 37V.
  • Designed around the LM2596 regulator with a switching frequency near 150 kHz for efficiency and stability.
  • High-quality capacitors and layout help suppress noise and improve long-term durability.
  • The front-panel voltmeter can be switched off by holding the power switch for a short period (1–4 seconds) and reactivated with a quick press.

Key safety and usability features

  • Reverse polarity protection via diodes helps guard against incorrect hookup.
  • Overheat and short-circuit protection provide an extra layer of safety for steady projects.
  • For power loads above 15W, ensure adequate heat dissipation to maintain performance.
  • Adjust output easily with a tiny screwdriver; no soldering required thanks to convenient terminal blocks.

Practical applications and benefits

Whether you’re building a car power supply, a DIY lab, or industrial-style test rigs, these modules offer flexible power shaping without committing to a fixed voltage. The 6-pack keeps multiple projects ready for experimentation and rapid iteration, helping you explore different voltages and configurations with less setup time.

Usage tips

  • Always verify input voltage is within the 4.0–40V range before powering a downstream circuit.
  • Use the voltmeter display to confirm the intended output while you adjust. Remember the display may not operate if the input drops below 4V.
  • When integrating with heat-sensitive components, consider heatsinking or airflow to manage temperature at higher loads.
