Power outages and voltage spikes can shut down critical equipment, cause data loss, and damage expensive hardware. When a server or medical device stops, you lose productivity, revenue, and sometimes even patient safety. The APC Smart-UPS RT 20kVA Rackmount 12U LCD 230/400V Online UPS gives you clean, uninterrupted power so your devices keep running while the grid recovers.
APC Smart-UPS RT 20kVA Rackmount 12U LCD 230/400V Online UPS with APC
Imagine a power source that never lets your servers blink. This unit is a high-density, double-conversion online UPS that sits in a standard 12U rack. It delivers up to 20 kVA of clean power and can be expanded with extra batteries for longer run time. If the mains fail, the UPS switches instantly, protecting your gear from sudden loss or voltage fluctuations. APCs reputation for reliability means you can trust the system to stay online when you need it most.
