400V 3-Phase Input and Output – Stable, Balanced Power Delivery

Built for commercial and industrial-grade applications, the APC Easy UPS 3S 40 kVA supports a 400V 3-phase input and 3-phase output configuration (3:3), ensuring even power distribution across all phases. This system minimizes imbalances, reduces stress on equipment, and promotes energy efficiency across the board.

Three-phase systems are preferred in high-load environments because they provide smoother and more reliable voltage than single-phase systems—ensuring your mission-critical devices operate at optimal levels.

Three Internal 7Ah Modular Battery Strings

The APC Easy UPS 3S 40kVA – E3SUPS40KHB3 comes equipped with three internal 7Ah modular battery strings, designed for maximum reliability and runtime. These batteries provide essential backup power during outages, giving your team enough time to execute safe shutdown procedures or switch to auxiliary generators.

The modular battery architecture makes maintenance simple and quick. You can replace or upgrade batteries without interrupting power flow, minimizing operational downtime.

Advanced VRLA Battery Technology

At the heart of the UPS lies its Valve Regulated Lead-Acid (VRLA) battery system—engineered for safety, durability, and minimal maintenance. VRLA batteries are sealed and require no water refilling, making them ideal for data centers, hospitals, and environments with limited battery maintenance capabilities.

These batteries offer excellent thermal stability and a long lifecycle, ensuring reliable operation in high-demand scenarios. Their spill-proof design also makes them safer for indoor environments.

Automatic Voltage Regulation (AVR) for Consistent Power

The APC Easy UPS 3S 40kVA features Automatic Voltage Regulation (AVR) technology that instantly corrects under- and over-voltage conditions without using battery power. This protects your equipment from damaging surges, sags, and spikes—while preserving battery life for actual power interruptions.

AVR makes this UPS particularly effective in regions with unstable power grids or frequent voltage fluctuations.

Smart Monitoring via LCD Display and Status Alarms

Monitoring your power system has never been easier thanks to the built-in LCD display, which provides at-a-glance insights into:

Input and output voltage levels

Battery health and status

Load percentage

Active alarms and fault diagnostics

In addition, audible status alarms notify users of critical changes in system behavior, such as low battery, overload, or hardware faults—allowing for quick interventions and minimized risk.

Compact Tower Design for Versatile Deployment

Despite its high capacity, the APC Easy UPS 3S 40kVA – E3SUPS40KHB3 boasts a space-saving tower form factor, allowing it to fit neatly in server rooms, IT closets, or control centers. Its sleek, modular design supports streamlined deployment without consuming excessive space—ideal for organizations managing limited physical infrastructure.
