AC-DC Buck Power Supply Module 12V 5.3A 63W | 100–240V Input
AC-DC Buck Power Supply Module 12V 5.3A 63W | 100–240V Input
AC-DC Step-Down Buck Power Supply Module — 100–240V AC to 12V DC, 5.3A / 63W
This compact yet capable AC-DC switching power supply board converts universal AC mains input (100V–240V) into a stable DC 12V / 5.3A output, delivering up to ~63 watts of regulated power. Ideal for embedded projects, LED drivers, DIY electronics, automation systems, and custom enclosures that require a reliable, board-level power solution.
Key Features
- Wide AC Input Range: AC 100V–240V — compatible with global mains voltages
- Stable DC Output: 12V / 5.3A (≈63W rated capacity)
- Dual Cooling Aluminum Plates for efficient thermal management during continuous operation
- 3.96mm Pitch Terminal Connectors on both input and output — or solder wires directly to the board without using terminals
- Dust-Proof & Moisture-Resistant Coating: protective conformal glue sprayed on the bottom side of the PCB for enhanced durability
- Compact & Lightweight: weighs approximately 220 grams — easy to integrate into enclosures and project builds
- Rated Capacity: <40VA (switching design for high efficiency)
- Low-Voltage Output: Below 50V AC / 75V DC on the output side (EU LVD compliant output)

Frequently Asked Questions
Q: What devices can this AC-DC 12V 5.3A power supply module power?
A: This switching power supply module is well-suited for powering 12V LED strips, CCTV cameras, routers, small motors, Arduino/Raspberry Pi setups with 12V peripherals, automation controllers, and other electronics requiring a stable 12V DC supply up to 5.3A (≈63W total).
Q: Can I solder wires directly to the board instead of using terminal connectors?
A: Yes. Both the input and output use 3.96mm pitch terminal pads that accept direct wire soldering, so you can skip plug-in terminals entirely and hard-wire connections for a cleaner installation.
Q: Does this power supply module work with both 110V and 220V mains?
A: Absolutely. The module accepts a wide AC input range of 100V–240V, making it compatible with both North American (110V/120V) and European/Asian (220V/240V) mains voltages without any manual switching required.
Q: Is the board protected against dust and moisture?
A: The back (bottom) side of the PCB is coated with a dust-proof and moisture-resistant conformal glue, providing an added layer of protection for the circuit. However, the board should still be housed in a suitable enclosure during use.
