1000 kVA Liebert 610T, one meg of power for your critical infrastructure. We have a tested and ready to ship one meg Liebert UPS in stock. Liebert has been the UPS of choice since the earliest days of the UPS. All UPS are professionally refurbished and load tested. We invite you to witness test this UPS system in our new state of the art facility, we will pay up to $500.00 for your travel to Phoenix.
