The APC Easy UPS 3S 20 kVA 400 V 3:1 UPS for Internal Batteries (part number E3SUPS20K3IB) is a double-conversion (online) uninterruptible power supply rated at 20 kVA and 20000 W output power, with a power factor of 0.99. It is designed for use with internal Sealed Lead Acid (VRLA) batteries at a battery voltage of 240 V.
The unit accepts input voltages from 304 V to 477 V at 45/65 Hz and delivers output between 220 V and 240 V at 50/60 Hz, with a maximum current of 37 A. Output voltage THD is 5.5% and the crest factor is 3:1. Connections are hardwired. The UPS has a rackmount form factor, an IP20 rating, a white finish and a storage relative humidity range of 0 - 95%.
As a three-phase-input online UPS, it suits power protection for server rooms, network infrastructure and other critical equipment that requires continuous, conditioned power.
