Easy UPS 3S 20 kVA 400 V 3:1 with internal batteries, 15 minutes
Double conversion online power protection for critical infrastructures that cannot stop. Delivers 20 kVA / 20 kW, three-phase input, single-phase output, and internal autonomy prepared to maintain stable operation during power failures, micro-outages, 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 modular internal batteries, reducing installation complexity and accelerating commissioning in professional environments.
Efficient protection
Delivers a strong balance of protection, autonomy, and cost for scenarios where the goal is to secure operation and ensure a safe transition.
Description
The APC Easy UPS 3S E3SUPS20K3IB1 was developed to protect critical loads with a solid combination of power, simplicity, and internal autonomy. It is a 20 kVA / 20 kW solution with a 400 V three-phase input and single-phase output, suitable for environments where operational continuity is essential, but where intermediate autonomy makes more sense than a larger battery bank.
The double conversion online architecture helps isolate equipment from grid irregularities, while the internal battery system supports up to 15 minutes of autonomy, providing margin for response, transition to a generator, or controlled shutdown of processes.
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.
