MPN #: OL3000HV
Power outages, voltage spikes, and brief blackouts can shut down a computer in an instant. When that happens you lose unsaved work, risk hardware damage, and may even lose important business data. The cost of a single lost file or a damaged server can be far higher than the price of a good backup system. The ATEN OL3000HV 3kVA 3000W Online Double Conversion UPS gives you a steady flow of clean power, so your devices keep running and your data stays safe.
Imagine a power source that never lets your computer pause, even when the grid flickers. This is an online double-conversion UPS that turns every incoming voltage into stable, filtered electricity before it reaches your equipment. It is built for offices, studios, and any place where a power glitch could mean lost money or lost data. With ATEN technology you get a battery that kicks in instantly and an LCD that tells you exactly what is happening.
The UPS fits in a 2U rack or can stand on a desk, so it works in server rooms, small business offices, and home workstations. It protects desktop PCs, network switches, medical imaging devices, and video-editing workstations. It also supplies power to point-of-sale terminals and security cameras that must stay online 24 hours a day. Wherever you need uninterrupted power, this unit can be plugged in.
