Function: A compact, singleswitch power supply that converts mains AC to stable DC for small devices, with a single on/off switch for simple control. Benefits: Easy to operate and install; compact footprint fits tight spaces; provides regulated DC output for reliable device performance; energy efficient with low idle loss. Compatibility: Broadly compatible with lowvoltage DC devices that need steady power; commonly used for LED lighting, surveillance cameras, small networking gear, and hobby electronics. Size and material: Slim, lightweight enclosure designed for desktop or wallmount use; enclosure material is durable metal or grade plastic depending on model. Performance and protections: Regulated output with low ripple and good load regulation; builtin protections (short circuit, overcurrent, overvoltage) to safeguard devices. Use scenarios: Powering a 12V LED strip under a cabinet. Supplying DC to a CCTV camera or DVR system. Powering a microcontroller project or small Arduino/Raspberry Pi setup. Quick setup tip: Verify the required output voltage and current rating before use; ensure proper polarity.
