variable power supply DPS5005 for makita LXT tool battery / USB-C / barrel plug

DPS5005 enclosure and circuit.

Power in can be:

• USB-C power delivery up to 20V
• Common DC Barrel jack plug up to 50V
• Makita LXT 18V tool battery

Variable output goes to:

• Banana style connectors
• Clamp terminals for quick connections

Additionally outputs a stable 5V on 2 USB plugs

A switch prevent a connection between the tool battery and other voltage sources. The USB-C and Barrel plug are not separated so connecting those at the same time might damage your power supplies. The USB-C decoy module requires a reverse voltage protection.

Search for something like 'Type-C PDC004-PD Pd Decoy Module PD2.0' for the USB-C power module, and for 'WP6 audio terminal' to find the clamp terminal block. The other components should be easier to find.
