Post Subject: AC quality is the biggest challenge in AudioPosted by Amir on: 8/1/2022
yesterday i had a conversation with an engineer who was in UPS industry in Tehran.he told me they install isolation transformer after UPS for better isolation for medical equipments.he told me most industry UPS manufactures produce Class D inverters and some models have output transformer and some models are transformerless.
we know "no high power industry UPS is optimized for Audio" and most of UPS in Audio Industry (like ps audio p20, pure power 3000, stromtank 5000) are low power (under 3000w). 
AC quality is my biggest challenge
