Your server room can't afford a brownout at 2am. This APC Smart-UPS On-Line keeps your critical gear running through the outage — no voltage sag, no reboot cascade, no 6am panic call to IT.
Double-conversion on-line topology means your load never sees the mains flicker. 1350W of clean, continuous power through 8 IEC C13 outlets with switched groups so you can shed non-critical loads and stretch runtime when it matters.
The lithium-ion battery pack is built in — no external box to cable up, no lead-acid to swap every two years. Battery life runs 5 to 10 years depending on duty cycle. Intelligent BMS tracks state of charge and health so you know where you stand before the next storm.
4U rack or tower. IEC C14 input, 230V. 1h 33min runtime at full 1350W load. 340J surge protection. 50 dBA — quiet enough to sit in a small server closet without masking the phone call you're trying to take.
Ships with rack mounting kit. Plug in, configure your switched groups, done
