Made in Mainland China.
Key Features
- Wide Input Range: Accepts DC 12V or 24V input and steps it down to a steady DC 4.5V output — perfect for powering devices that require lower voltage from a higher-voltage source.
- High Current Output: Delivers up to 3A of continuous current, making it suitable for LED strips, small motors, fans, and other moderate-demand accessories.
- Low Ripple & High Efficiency: Engineered for stable, clean power delivery to protect sensitive electronics from voltage fluctuations.
- Battery Replacement Solution: Acts as a reliable substitute for 3×1.5V series battery configurations, eliminating the need for frequent battery swaps and reducing waste.
- Standardized DC Connector: Features a DC 5.5×2.1mm plug (center positive polarity) with a 26cm output cable and color-coded 13cm input wires (red/black) for hassle-free installation.
- Compact & Lightweight: Measures just approx. 46×27×15mm — small enough to fit into tight spaces and portable enough for both stationary and on-the-go applications.
