APC Easy UPS 3S 20kVA 400V 3:3 with Internal Batteries

APC Easy UPS 3S 20kVA

The APC Easy UPS 3S is a high-performance, three-phase uninterruptible power supply designed to provide robust power protection for small and medium-sized business environments. This specific SKU features internal batteries that offer immediate backup runtime without requiring external battery cabinets. The system utilizes a double-conversion online topology to ensure a clean and stable power supply, protecting critical hardware from voltage fluctuations, surges, and total power failures. Consequently, it maintains operational continuity for data centers, telecommunications infrastructure, and industrial facilities. The unit supports a 400V input and output configuration in a 3:3 phase arrangement, delivering a unity power factor of 1.0, which means 20kVA equals 20kW of real power capacity.
