Powerpole Distribution Box Project

A DC power distribution board using Anderson powerpole connectors

[PCB Design]

Status

• Completed, designs are available at Github

Feature List

• 6 power-pole connectors
• Individually fused connections with indicators
• 30A capacity (Limited by current rating of the fuse holders)

Build instructions

Components

• 1 x Powerpole Distribution PCB
• 4 x Acrylic layers with various cut-outs (3 x 5mm layers, 1 x 3mm layer)
• 4 x 25mm M3 steel bolts
• 4 x M3 steel nuts
• 6 x Powerpole contacts
• 6 x Black plastic powerpole housings
• 6 x Red plastic powerpole housings
• 12 x Fuse holders
• 6 x Variously rated (and coloured) fuses
• 6 x capacitors
• 6 x 330ohm resistors
• 6 x 3mm red/yellow LEDs

Tools Required

• Soldering iron - high power (45W+) with a large tip as there is a large thermal mass.
• Sidecutters
• (Recommended) Helping hands or other PCB support tool.

Instructions

1. Solder resistors, capacitors and LEDs onto the PCB.

2. Push fuse holder contacts through the holes in the PCB.

3. Solder fuse holder contacts. These will suck up the heat, so may take a while to get up to temperature

4. Attach the to top two acrylic layers and attach the partly-populated PCB using the nuts and bolts provided.

5. Assemble the powerpole contacts by joining them together and inserting the contacts into their housings

6. Place the powerpole contacts onto the PCB. To ensure correct placement, the top acrylic layers should be fitted first, otherwise the spring of the powerpoles will cause these layers to be offset.

7. Solder the powerpole contacts onto the PCB. The most straightforward way found to do this is to push the PCB and powerpole contacts down onto a hard heatproof surface, so that they sit in the correct place whilst they are soldered. They should be soldered as quickly as possible to avoid the powerpole housings melting due to too much residual heat.

8. Check for any solder bridges across both the fuses and powerpoles.

9. Assemble the remaining two acrylic layers of the case and attach to the already assembles layers and PCB.

10. Enjoy your Distro!
