Hello all,
First post here so hoping it's in the correct place.
Straight to it... I'm into astrophotography and wanting to use a single power supply that will control my setup - I'm sure that's a line from a film (Lord of the Rings in case you missed it).
So, I have a 12V supply to power my mount (it actually outputs 13.8V with plenty of current to spare, so power requirement is fine - link). I'm also running a 12V-5V Buck converter (link) and powering a Raspberry Pi mini PC via a USB cable. So far so good.
My issue is the camera power supply - I have a mains camera dummy battery which works and supplies 8.3V. In an attempt to use the PSU above, I tried a buck converter approach (link) using 2 in series, to reduce the 13.8V to 10.8V and then 10.8V to 7.8V, but couldn't get the first to output more than 5.7V so that approach wouldn't work. Perhaps a dud-first one, I never tried others and sent the order back.
I then purchased (two) 12V-8V step-down adapter (link) which should have worked with my camera, but the first one didn't even put out 1V so sent back and tried a second which worked for a night before giving up on me.
I'm therefore left with two options - use another 12V-5V USB buck as per the RPi, and then a USB camera power cable (link), or ask advice on adjustable buck converters which will do the job of the poor quality Amazon one. Hence my post here. Going from 13V-5V-8V seems a bit silly and adds extra components and cost, but is likely to work well, but I'm more interested in going for a 12V-8V converter that will do the job for me and work.
TLDR:
Looking for a means to convert 13.8V to 8.3V for a DSLR - recommendations appreciated as have been unsuccessful with duds to date!
Thanks in advance!
