APC Easy UPS 3S 15kVA Online UPS - E3SUPS15K3IB1

The APC Easy UPS 3S E3SUPS15K3IB1 is a 15 kVA three-phase online uninterruptible power supply designed for reliable energy continuity in professional environments. This double conversion system features a 3:1 crest factor, ensuring compatibility with high-peak loads typical of server racks and IT infrastructure. It includes an internal 240 V DC battery string providing nine minutes of runtime at full load.

This three-phase online UPS delivers rated power of 15 kVA / 15 kW with a unity power factor (cos phi 0.99), optimizing efficiency for modern IT loads. Input voltage accepts 400 V AC at 3-phase with an input frequency range of 45 to 65 Hz, while output provides stable 230 V AC synchronized to the mains frequency. The topology ensures double conversion online protection, reducing input harmonic distortion below 5% and maintaining output harmonic distortion under 3%. With a maximum output current capacity of 10 kA short-circuit withstand capability, it safeguards sensitive equipment against electrical anomalies.

The unit houses one internal 7 Ah VRLA battery string operating at 240 V DC, offering nine minutes of runtime at rated load. Additional backup time can be achieved by expanding to up to three external battery strings. Physical dimensions are 140 cm height x 38 cm width x 90.7 cm depth, with a weight of 71.21 kg. Operating between 0 and 40 °C, it maintains an acoustic level of 60 dBA and carries IP20 ingress protection ratings for indoor deployment.
