Lab Power Supply (Cheap & Powerful)

myminifactory

This power supply is surprisingly affordable, costing between 50-60 euros in parts. It's incredibly powerful and well-suited for laboratory or workshop use. The device consists of three printed pieces made from PLA/ABS material, except flex. It outputs adjustable voltage and current levels in extremely fine increments, ranging from 0 to 45.00V and 0 to 5.000A respectively. While it's not perfect for precision electronics due to some electrical noise, it will suffice for most workshop applications. The power supply is also impressively accurate when setting voltage and current levels. Another notable feature is its complete silence, eliminating the need for a fan. To build this power supply, you'll need several components: a 250W 48V AC-DC transformer/power supply, an adjustable voltage/current buck (50V 5A), three-core mains cables, four female plugs (two red and two black), a standard 10 or 16A 250V switch, a 5mm red LED (optional), and a 10k normal resistor (optional). You can source these components from various online retailers like eBay, AliExpress, or local electronics stores.

Keep in mind that this power supply operates on 220V, so please exercise caution when working with it.
