Cleaning up dirty power
Posted by: Spiff
Date: November 16, 2022 09:26AM
Greetings electrical gurus! I have a piece of equipment at work that is sensitive to dirty power and frequently get interference in my readings when I am trying to use it. It comes and goes, so something must be cycling on the same circuit. My company WILL NOT dedicate a power outlet to just this piece of equipment. Plus, I am in a building that is over 50 years old, so I am sure that there have been some creative solutions to electrical problems over time.

Is there a way to plug a "conditioner" of sorts to the outlet which will clean up the power? I am ok with trying something in the $200-$400 range, if that helps. Thoughts?

Thanks!

PS - I've done a quick interwebs search and have found little to nothing so far. I am guessing I am not searching the correct terms. My google-fu is weak this morning.

here are 2 I have used in NYC recording studios, home of dirty power and "don't worry. It'll be quiet once the subway passes".
I doubt they'll make your budget, but might get you some leads from reading their stuff.

a UPS type unit may work for you and they're less $$$, but dunno for sure.

What kind of voltage and amperage are you talking about ? I can ask my nephew who is an audiophile equipment rebuilding maven. My solutions would be old and military specification.

Fritz's concept of a battery charger to a battery to an inverter pure sine wave power source may be the most modern solution.

does your nephew want to buy a working (60lb) McIntosh MC2120 SS amp?

cbelt - good questions. I am unsure.

The equipment consists of a computer running Windows XP - 14 years old. There is an amplifier attached to the computer that delivers electrical impulses up to 100mA at 1ms stim. The amplifier records in milliamps as well. I am doing nerve conduction studies, if that helps.

I like the solutions that Fritz suggested, but i noticed that the sites are designed so that if you HAVE to ask how much, they aren't an option grinning smiley

I have read about attaching a power supply, but I think the tricky part will be to ferret out which one will do the trick. Thoughts on that end?

Thanks!

nerve conduction studies might help my leg.
phone call is free. I'd call both or use their sites to make other googs.

You can find quite a few in your price range, here is an Amazon page of them - [www.amazon.com]. You just need to know what amount of power they need to deal with.

Personally I have one that was left behind when the contract for leasing copiers where I worked switched from Canon to Xerox. That copier was located on a circuit that had a lot of interference that kept resetting the electronic controls, the conditioner they used was rated for 15 A.

your link was broke.
I assume this was it, more or less.

Check with a local medical supply company. They have power systems which are used for critical medical devices. They usually are rented so maybe you can rent one to see if it solves the problem.

Don't know why the link broke, it still works for me. Change the search to Line Conditioners and that gets what I saw - [www.amazon.com]

I've done well on this kind of equipment on craigslist and ebay. Have to be careful about condition, though.

you deal with very, very small voltages. Make sure you don't have a ground loop, bad ground, and use differential input when possible.

Completely isolate everything and use this:

[or similar]

Just plug it in to recharge between measurements.

Tripp-Lite conditioner. My guess is that you can use the smaller models, as you are looking at one piece of equipment and small voltages. After that, I'm useless!

and around here, 50 year old building is considered "newer."

Nice amp. I've got a 2100 in the closet. Haven't used it in years but can't get rid of it.
