Questions about this item

At what input voltage does the unit switch to battery instead of correcting with AVR?

The automatic voltage regulation corrects from 83 VAC to 159 VAC without using the battery; outside that range the UPS transfers to battery power.

What is the maximum heat output when the UPS runs continuously at full load?

At the full 2700 W rating the unit dissipates heat equivalent to that load, so plan cooling for a 2700 W continuous thermal contribution.

Which communication card must be installed to enable remote monitoring of this UPS?

An optional Vertiv Liebert Unity communication card is required to monitor up to 50 UPS systems with the free Vertiv Trellis Power Insight application.
