I've got a small fridge for cooling drinks that runs on 120vac, 12vdc, or 24vdc. The 120vac option uses an external power brick and puts out 12vdc to the fridge. I'm currently using this on my 120vac side, but would prefer to have the fridge on the LOAD circuit using PWM Divert or Diversion mode. I'm not sure if the compressor actually runs on 24v or 12v OR it steps the 24v down to 12v. If it does step down, would this harm the kids load circuit like an inverter might?

Look at the output of your 120 v power converter and see what the output is.
My guess i the compressor runs on 12v since that is lowest rated power for it - everything else is down converted or the compressor itself or controls can handle the 24v and convert it there.
You don't want to PWM it - which is cycling the power on and off real fast - that would be bad or ruin the compressor or controls.
You could use anything else that provides it power on or off as long is it doesn't go on and off real fast.
I am not sure how many watts the Kid diversion is rated at - looking at your link and answered questions it looks like it takes 76 watts at startup surge and then might settle out at 45 watts.
You can always use the Kid Load to control another relay that can handle the refrigerator load.
I only looked briefly at the questions and anwers on the Amazon link - you might want to read all of those and see if someone answers your question about power .

Good call on the PWM. The brick definitely supplies 12v...I like the relay idea, seems like the safest route.
Package includes: 1 x Refrigerator, 1 x DC Power Cord, 1 x AC Adapter, 1 x Manual
use the DC cord to a fuse block like Blue Sea Systems ST Blade ATO/ATC Fuse Block. u could use heavy duty cigarette lighter socket with a fuse but id go with fuse block.
ã€Battery Protection & Low Noiseã€'There are 3 different levels for battery protection: Low, Med and High.
set low battery voltage good for sla agm batteries. not good for Lithium since they go much lower voltage.
no need to use load circuit for low battery protection.
most auto detect voltage on 12v or 24v check manual
