BTF-LIGHTING AC100-240V to DC5V 20A 100W Power Supply for LED Strips & CCTV

Overview

The BTF-LIGHTING AC100-240V to DC5V 20A power supply is designed to convert worldwide mains into a stable 5V DC output, delivering up to 100W of power. It’s ideal for 5V LED projects, LED matrices, and compact CCTV or security setups. With an adjustable output range of ±10% (4.5V–5.5V) and a wide input window (110V–240V, 50/60Hz), you can tune performance to match your device while staying within safe limits.

How it works

The switching design emphasizes efficiency and reliability. A porous metal shell aids heat dissipation, helping maintain steady performance in real-world conditions. The compact footprint makes it easy to place in cabinets, racks, or on desktops. For safety, ensure the device is used indoors and switch the input voltage correctly before powering up.

Safety and reliability

Built-in protections include automatic overload cut-off, over-voltage cut-off, automatic thermal cut-off, and short-circuit protection. With a robust 100W output and a stable 5V supply, your connected electronics are safeguarded against common power irregularities. To extend component life, operate at or below about 80% of full load.

What you can power

This supply is well suited for classic 5V applications and devices that draw steady current, such as WS2812/WS2812B LED strips, SK6812 pixel matrices, LED strings, CCTV cameras, and basic security or computer projects requiring a reliable 5V source. It provides a flexible option when you need a single, dependable power module for multiple small builds.
