Description

PDF

This enclosure houses a power supply that converts 24Vdc to 5VDC and 12Vdc.  The 5Vdc is output on a USB-C case mounted connector.  The 12Vdc is likewise output through the case using a standard 12Vdc 5.5mm round female PCB mounted connector.  Both outputs are rated at 3A each.  Input is on a pigtail that connects to a 24Vdc power supply and is soldered directly the breadboard.

The conversion is via two Drok buck converter boards which are mounted on a Breadboard PCB using Dupont straight pins.  The 24Vdc input is wired to Common and Vin on both converters using discrete wires on the back side to the PCB.  The outputs are likewise connected to the Common and Vout pins for their respective converters.

The bottom case has slots for the USB-C connection wire and the Vin Wire to allow the wires to be soldered to the PCB before assembly.  The Top case has filler flanges that cover the slots in the lower case except for the amount of opening necessary for the wires.  The bottom case contains mounting tabs on either side suitable for M3 mounting hardware.

The top case is friction fit to the bottom, requires no hardware, and provides tabs to hold the PCB in place.
