WHITE PAPER –
The Impact of UPS Autonomy on Reliability and Safety
Longer autonomy does not increase data center reliability
Uninterruptible Power Supply (UPS) autonomy time — the interval that a UPS can support its critical load on battery power alone — has historically been determined by the characteristics and limits of electrochemical lead-acid and lithium batteries. Hybrid supercapacitors (sometimes called superbatteries or HSCs) offer the potential to match UPS autonomy times to operational requirements while improving reliability.
