Hello Everyone,

I'm trying to understand the reason why the AVR step down on BR1000G-IN is 252 Vac-282 Vac -17%. I'm worried an Output voltage this high would potentially damage the devices connected to the UPS.

I spoke with APC Technical Support and was told the UPS replicates the same Input Voltage to the Output until it reaches the AVR high voltage limit, i.e. 252 Vac

Technical Support counter argument - This UPS is meant for PC's who's SMPS also has AVR to deal with such high voltage, which wasn't very convincing as I have other devices connected to this UPS - Home Routers, Printers which are rated max 240V and do not have a regulated power supply as a PC SMPS

AVR was a significant feature i bought this UPS for, doesn't this impractical upper voltage range render the AVR function on this UPS useless ?

Any feedback and comments are welcome.

Hello SecretSquirrel,

Thank you for taking the time to review my concern. Both EN-1000 and BR1000G-IN are 1000VA 600 Watts Indian models hence do seem to qualify for valid comparison. Eaton's Eco-100 seems an Australian model not available for sale in India.

On the BR1000G-IN product box, APC does mention this product is suited for a typical home office setup including DSL modems, wi-fi broadband routers (which do not have a regulated power supply) hence I bought this product. I couldn't find any official recommendation of the connected load to have a regulated power supply on the product page either.

I may have been mislead by the following official explanation of AVR for BR1000G-IN - "Boost and Trim Automatic Voltage Regulation (AVR) - Eliminates voltage fluctuations as a source of AV signal degradation and component power-supply stress" but I agree with you that Voltage stabilizer and UPS are intended for different use cases and I'm not expecting the UPS to do Voltage Regulation either. Just that the Trim function on BR1000G-IN is hardcoded to kick in on 252V which should ideally be 240V.

I have a home office setup with voltage sensitive equipment like VOIP Phone, Network Load Balancer etc connected to the UPS and hence really worried when i see the LCD indicating Output voltage 252Volts during a spike. I'm not sure if those extra 12V volts matter but i don't want to wait till something blows off either.
