Easy UPS 3S 20 kVA 400 V 3:1 with internal batteries, 30 minutes
Double-conversion online power protection for critical infrastructure that cannot stop. Delivers 20 kVA / 20 kW, three-phase input, single-phase output, and internal autonomy prepared to maintain stable operation during power outages, micro-cuts, and fluctuations.
Real Continuity
Keeps essential systems operational when the grid fails, reducing the risk of downtime, data loss, and critical interruptions.
Stable Power for Sensitive Loads
Double-conversion online topology helps deliver a cleaner, more predictable output for servers, networking, storage, and critical electronics.
Integrated Autonomy
Includes 3 internal modular battery strings, reducing installation complexity and increasing support time during power failures.
Extended Protection
Delivers a greater response margin for generator transition, operational continuity, or controlled shutdown of critical processes.
Description
The APC Easy UPS 3S E3SUPS20K3IB2 was developed to protect critical loads with a solid combination of power, simplicity, and extended internal autonomy. It is a 20 kVA / 20 kW solution with 400 V three-phase input and single-phase output, suitable for environments where operational continuity is essential and where superior autonomy offers a more comfortable operating margin.
The double-conversion online architecture helps isolate equipment from grid irregularities, while the internal system with 3 modular battery strings supports up to 30 minutes of autonomy, offering more time for response, generator transition, or uninterrupted operation.
It is a UPS designed for professional environments, with a vertical format, simplified management, and consistent performance for technical rooms, IT infrastructure, telecommunications, automation, and other applications that require stable and predictable power.
