Advice on how to hook-up the device being powered. + goes to PSU #1 and - goes to PSU#2? ... or should there be a buss bar connecting the + & - between the two PSU's and then the device would connect to the buss bars. Am I over-thinking this?
You added the question mark as if you were asking me a question, so I'm not sure of the intention of your statement. I do realize the concept of series and parallel as it relates to voltage sources.parallel would be - to - and + to + and the parallel connection to parallel connection just to keep the regulators in sync?
I wouldn't connect + to -,, that's how series wiring works and doubles the voltage,, you want parallel wiring to double the amperage
1) I'm not sure what the Astron's parallel link wire does, I'll have to study the schematic.1) Normally when you jumper the posts in the back labeled for paraller operation only the voltage reulation and hence output is controled by one of the supplies. It becomes the master and the other is the slave.
2)i have heard two different ways to hook up the dc. One says to bridge them as you did the other says to take the pos from one and the neg from the other. Never ran two astrons before so i couldn't say.
1) Couldn't find a manual for it.1)Do any of the Astron manuals describe how to do it?
2)Might send them an email or call them.
3)I read an old thread on Fwed's site, they all seemed confused and in disagreement.
Correct about the above. I used to run three 50 amp Astrons to a solid state amp. The special lug on the back goes to circuitry that is designed specifically for running these PSs together. The wire you run from one PS to the other is a link between them. You do not take power from this link. You use the main power lugs to hook up your equipment. Also when hooking up, take the + from one PS and the - from the other this was suggested to me from one of the Tech's at Astron.73
Thanks for doing some of my homework for me CK. I just went through the schematic and there is no mention of the parallel hook-up port.I wish you the best of luck. I looked at the schematics and found nothing about the jumper link for parallel operation. i also read the operations manual and Astron seems to be keeping this one a secret. They have no mentions tat all about how to do it even though their heavy power supplies are capable of doing it. i even googled it and that is where i came up with both ideas. Yeah it seems odd to me about taking the pos offf one and the neg off the other but that is what a couple people were saying. Maybe they were talking about getting 24 volts but they were talking about in parallel for 12 volts. It would certainly help if Astron would just stop the foolish....no idiotic, secrecy and just tell people how to wire it up in their manuals.
Good idea. I have a test subject in mind. I am awaiting some eBay Anderson connectors that are on the way, so final test results will be delayed until I receive them.I would hook them up that way and test it with a volt meter if you have one. Next I would hook up an old car headlamp or something made for 12 volts that will draw several amps first before connecting anything too valuable to it. You know....just in case.
