Ultimate Lab Power Supply | DIY | 1500W
Print Profile(1)

Description
It all started with my first USB-C lab power supply. I used it frequently and enjoyed it, but I noticed a major problem: the power. The built-in buck-boost module only delivered 45 W, while I often needed more. After an intensive search, I found the most powerful module available was just 90 W – better, but not enough.
The best nearest solution was the ZK10022, which delivers up to crazy 1500 W, but only as a buck converter. To implement a powerful buck-boost function, I opted for an 1800 W boost module that can handle up to 40 A input current for best input source
flexibility. I also made the power supply a bit more versatile: A 120 V step-down module generates a stable 24 V via the boost converter, which can be used via a 5.5 mm jack and a 65 W power delivery module. A USB-C trigger module also enables inputs via USB-C it also has banana jack and 5.5mm Jack inputs. For the Outputs I wanted banana jacks and 5.5mm Jack. The ZK10022 had a Power switch so I soldered wires to the switch and put a bigger nicer switch in the front plate.
I chose 3D printing for the enclosure because of its flexibility. I also used a carbon textured plate for a nice and clean finish.
The total cost is about €75 with aliexpress prices, for this monster of a power supply – and there's no comparable alternative on the market for that price.
