This constant current DC power supply provides a fixed 12.6V DC output with a constant 10A current output. It is a straightforward option for projects that need a rugged, enclosed supply for compatible loads such as LED lighting-type devices.
The unit is built into a robust metal enclosure with an IP68 rating and uses pre-attached colour-coded leads. Red and black wires are used for the DC input, while yellow and black wires provide the 12.6V output.
It can also be used for charging Li-Ion batteries, but only where the user has good knowledge of the correct charging requirements and safe battery handling.

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- load regulation
- Load regulation describes how much a power supply’s output voltage changes when the connected device draws more or less current. Better load regulation helps keep test circuits powered at the voltage you set, even as their current demand changes.
