10A DC-DC Adjustable Step Down Power Supply Module With LCD Display And Case – CC/CV, Green

This is a handy little 10A DC-DC adjustable step-down power supply module.

It's got a constant current (CC) and constant voltage (CV) feature, plus a dual LCD display so you can see exactly what's going on.

It comes in a protective case, all in green.

Perfect for DIY electronics projects, battery charging, or bench power supply builds.

It's a generic unbranded module, made in China, but it's a solid, functional piece of kit.

You feed it a higher DC voltage, and it steps it down smoothly to your desired lower voltage, up to 10 amps.
