and dont put the power in like that.
if those are socket-posts for a 4mm banana plug then get a pair of plugs and solder them to the wires.
using posts like that at hgh current is asking for trouble.
I'm using a cut apart pci-e signle molex adapter connected to some old seasonic psu. it works ok but input voltage drops to a bit above 11 and the wires are certainly quite toasty
not a good solution permanently but ok to test. running an hp desktop without a hard drive and a random dell laptop ok... but if i put a hard drive in the hp desktop the laod is too high and it starts to beep. either that or the input voltage drops too low.
will open it up and check. anything in particular i should be looking for?
All fuses in parallel? They do that a lot.
Single input fuse 12V @35A is 420W, but if the fuses are parallel then it sure does not look like 1000W unit, the input wires are small and connected in parallel.
So it's either a great 300W unit or a terribly over-rated 1000W unit? lol
Should be fine to charge the occasional laptop. What gauge wire do I need to bring 12V from the battery? I want to put an inline fuse near the battery, then bring some decently thick wires through a pre-drilled hole somebody made in the cab from the engine bay, then break it into a sort of 12v "power strip" if you will... two cigarette lighter sockets, a 5v usb, and the inverter.
Yeah, I was thinking somewhere in that range. I'd probably say 500W to be safe xD
Looks generic to me, no manufacturer labels anywhere that I can see.
Cheap looking caps.
Also, some of the chips are in sockets, not sure that I like that, but they don't look corroded (from what I can see). So they are probably fine.
LOL!!! Look how they removed the dust cap/tab thing from the buzzer/speaker and stuck it on the transformer! Lazy workers! xD
Also, I'm not sure why the input power wires go to the side with the small heatsink. I would think that the other side, with a whole bunch of transistors, would be the input side. Plus, I would also think that the input side transistors would have more losses, so they should be on the case, where they can have more heat dissipated.
