Description

I designed this enclosure for a DIY Adjustable Power Supply based on the LM2596 Constant Voltage / Constant Current module.

This case is designed to hold all the components including the LM2596 module, voltmeter/ammeter display, potentiometers, switch, banana sockets, and DC input jack.

The enclosure is compact, easy to print, and designed for front panel control of voltage and current.

You can watch the full build video and wiring tutorial on my YouTube channel.
