GODOX WB29 AD200 PRO power supply adapter by rstcologne

Last crawled date: 3 years, 4 months ago

The AD200 Pro is actually intended for mobile use and therefore comes with a battery. I had to do a longer shoot indoors, shooting a large number of people individually. I didn't want to run out of juice therefore I was looking for a way to connect a power supply.
This thing is an adapter for the original battery which can be wired to a suitable power supply.
The thing consists of two parts, one is the battery adapter itself, the second is the lid. I have used cable shoes (see image) to provide the contacts.
Steps to create:
1.) Print the case
2.) Print the lid
3.) feed the cable through the hole in the lid, I put a knot in the cable to protect the contacts from tension.
4.) connect the cable shoes and feed them through the holes in the case (check polarity, which is also indicated on the lid)
5.) Use some hot-glue to keep the contacts in place and bend them to shape (or vice versa)
6.) Glue lid and case together with CA glue
I added an XT30 connector to my adapter to be able to separate supply and adapter.
I'm using a 15V power supply which is well within range of the battery voltage (nominal charge 14.4 which means Godox ships a 4 cell battery. Fully charged this battery provides 16,8v so a 16v laptop supply might also work),
I couldn't find information about the necessary current so I experimented a bit. A 5A rated supply was not sufficient. I'm now using a MeanWell RSP 200-15 which is rated at 13,4A at 15V. This is enough and works flawlessly.
The picture showing the power supply uses this thing as a terminal cover: https://www.thingiverse.com/thing:3572269 (thanks for sharing).
DISCLAIMER: The above works flawlessly for me. However use this at your own risk. The suggested MeanWell supply uses an open contact bar to connect mains voltage. You should know what you are doing dealing with mains voltage. Also the supply only has a wire mesh casing at the top. Small things like screws can fall inside and cause shorts. Do take appropriate precautions when dealing with it on set. I put mine in a casing (after taking the uploaded picture) as is intended for these kinds of supplies. If in doubt, try to find a suitable power brick like a generic laptop supply. Also make sure you are using cables with a diameter sufficiently large to handle the current.
