Do you use a UPS? - Comments please

I have been involved in discussions regarding the merits of isolation transformers when balancing mains lines, generally for equipment isolation against common-mode noise on incoming mains.

However, not being able to readily source a suitable (2KVA) isolation transformer nearby, I am considering a UPS of equivalent size to power the entire studio.

Naturally, this would additionally provide protection against drop-outs and mains spikes, though I would be interested to know if anyone has established whether a UPS is a fair alternative for an isolation transformer in reducing common-mode noise (and of-course choking out differential noise)? Clearly there could be inverter noise from a UPS and perhaps not the ideal solution if this were significant.

I don't normally have an issue except when the studio air conditioner is running (from a separate wall-socket of-course!), or the washing machine on a common circuit, where tiny switching transients are only just detectable when they cycles on and off. I could use a proprietary mains conditioner of-course, though with the recent storms (and accompanying mains fluctuations) we've had lately, I'm developing a leaning towards a 2KVA UPS

Does anyone use a UPS to directly feed their gear and, if so, what are your experiences please?


Many thanks,

Brendan.

Absolutely - I have a Belkin that has saved my butt on a couple of occasions when the power went out here. I haven't noticed any line noise caused by it - in fact it seems to have reduced noise.

FWIWYMMV
