i have a power conditioner it is about the size of a ups and weighs about as much as a pc. it apears to bee pretty old. what do these do other than surge protection. it is also isoled from input to output. i read that electronic repair technitions use isolation transformers to avoid making shorts during testing.and ruining equipment. this one will put out 8 amps.
also because of the isolation i am wondering if it will use more power than what gets pluged in it. like if it always will take 8-9 amp to make like 3 amps of output.

A Power Conditioner will likely use a tank circuit or some other method to smooth your AC. A good one will also use one of several methods to adjust for more prolonged input voltage drops or overvoltage. AC voltage regulation is a bit different than DC regulation and not quite as common.

It should take only a little more power than its output needs.

Sometimes old equipment has features you can't (affordably) buy any more.

this is a rte deltec power conditioner. mpc 1060, p/n 65134138-9. s/n39498. inut 120v 9 a 60 hz. output 120v.8.4a 60hz. (intended for instalation in a protected enviorment.) cooling or surge protection or mouisture protection?

It could also be a "ups without battery", i.e. it rectifies mains voltage, and then uses a SMPS to generate AC.

One post specifies 120V in, 120V out but when you fired it up you only got 22V out of it?

At first it sounded like a Sola regulator, the type that's actually an isolation transformer with an extra winding for a resonant cap.

when i booted it op the voltage started around 40-50 and built up to full off 122. i toook of the fromt cover and there is a transformaer about the size of a coffe can. looks like the primary is wired directly to the cord through a fuse and switch.
there are 5-6 output wires that go to a circuit board this a sarly big bridge rectifier bolted to it in the corner.and the single outlet comes off this board.

Sounds like a mystery item to me, if you can't find any info on it you might have to draw a crude schematic to figure out what it is.

i know it is a power conditioner. thats what the label says i am just wondering what there purpus is. from what i have heard it is like a surge protector. and if you have a brown out. lower voltage like 90volt input it will make it normal. i think there also supposed to reduce electronic noise and emi from motors and microwaves. is this correct. and that post that i said 22 i ment 122.3 to 122.4.
