i assume you are speaking of the BR550GI - [seen here|http://www.apc.com/resource/include/techspec_index.cfm?base_sku=BR550GI]

on any UPS, you can see the topology, listed on the product overview tab..[seen here|http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=BR550GI&tab=features]

at the bottom of the page, it does indeed indicate that it is line interactive.

Every UPS that has voltage regulation built-in, is a line interactive UPS.
