@deostroll There are several families of JST connectors. Some are probably too small for that tool. Some might work with that tool, I would guess.

@NickAlexeev do traditional dupont sockets/pins fit in some type of jst connectors?

How did those connectors even get called "DuPonts"? I don't think DuPont even makes connectors

@W5VO Do you know where I could find a 50 volt 10 amp AC to AC transformer at? I've looked around but I'm only seeing 48 volt 5 amp transformers. I need a 10 amp 50 Volt AC transformer so I can convert it to DC then use the DC to power a fan system and a thermoelectric Peltier device.

@W5VO I suppose I could connect a few in series-parallel to get the current and voltage I need. Well the current I need but higher voltage than I would need. But all I would need to drop the voltage is a long length of wire. Because of the natural voltage drop. But I'd like to only use 1 transformer for my needs instead of 2.

@ScientistSmithYT I've got a 50V 50A DC supply I could sell you, but I've never powered it up and I don't have time to ship it. You really just want to get a AC-DC power supply, as a well-built 500VA transformer is heavy and expensive.
