We run half solar power here in the Philippines... My Imac shuts down every time the solar battery turns off. iMac is 110V from the US... I use a step down transformer to plug in to 220V. I want to get a UPS (unninterrupted power supply) to keep it from crashing. Do I need to run my transformer in to this UPS? Can I plug my 110V Imac in to a 220V UPS? (without is burning up?) I appreciate anyone's help here. Jim

imacs can be powered by from 110 to 240 it regulate itself you need not add transformers to the mix it could likely cause issues if you do so

The iMac power supply is universal: auto-senses input voltage and adapts accordingly - steps not necessary.
Separately, the iMac recovers from power outages as soon as power is restored - see Energy Saver Settings. If your programs auto-save files periodically and/or if you’re on iCloud, there’s no need for a UPS (which comes with risks of its own).
If you have other concerns, say a mechanical Fusion Drive inside, the UPS may make sense.
Thank you for that. I've been in the PH for 2 years now, and using a step down transformer... afraid to injure Mr. Mac;~ If it doesn't hurt the Mac to shut down when the solar goes off, I'll just save regularly and live with it. I appreciate your time to reply. Jim
