EVI UPS Battery Expansion Module for 10-30kVA 3:3 Phase UPS Product Guide
Comprehensive Product Overview
The EVI UPS Battery Expansion Module (Model: EP-UPSYABC9A80) is an enterprise-grade external battery cabinet engineered to dramatically extend the backup runtime of high-capacity 10kVA to 30kVA three-phase (3:3) online uninterruptible power supplies. In mid-to-large-scale computing facilities, a primary three-phase UPS provides vital, instantaneous protection against immediate voltage fluctuations. However, sustaining complex database frameworks or manufacturing operations during a major power line collapse requires a larger reserve of stored energy. This high-density expansion module serves as a scalable energy bank, offering the crucial bridge time necessary to launch standalone diesel generators or safely migrate mission-critical virtual cloud servers.
Housed within its heavily reinforced industrial steel structure is a massive, unified network of 80 high-capacity 12V 9Ah sealed lead-acid (SLA) batteries. These valve-regulated lead-acid (VRLA) cells are configured into a high-voltage split-bus DC architecture tailored specifically to match the demanding charging parameters of 3:3 phase enterprise online platforms. Because managing emergency loads for a 30,000-Watt infrastructure creates extreme direct current spikes, the cabinet utilizes heavy-duty internal copper busbars and isolated wiring runs. This structural layout safely facilitates deep discharge cycles without risking thermal bottlenecks, cell warpage, or connection fatigue.
The system architecture is engineered with flexibility, featuring a convertible rack/tower ready configuration that mounts smoothly inside standard 19-inch enterprise enclosures or stands vertically in dedicated battery banks. For continuous uptime operations, the module features a hot-swapping framework that enables certified technicians to execute internal component maintenance or cell testing without shutting down the primary UPS or disconnecting power to the active datacenter gear. It stands as an essential infrastructure asset for corporate business continuity, medical hubs, and manufacturing grids
Key Features
- Massive Runtime Multiplication: Provides extensive extended backup durations for critical loads managed by 10kVA, 20kVA, and 30kVA three-phase UPS systems.
- High-Density Battery Array: Pre-populated with 80 premium 9Ah leak-proof, maintenance-free sealed lead-acid batteries
- Zero-Downtime Hot-Swapping: Engineered to allow internal maintenance, testing, and cell replacement without interrupting the active data loaD
- Flexible Rack/Tower Chassis: Slips directly into standard 19-inch enterprise server cabinets or deploys standing vertically.
- Advanced Safety Circuitry: Outfitted with independent heavy-duty DC circuit breakers and high-speed protection fuses to guard the bank against short circuits.
- Smart Charger Communication: Integrates with the host three-phase UPS management platform to dynamically balance the charging current and prevent cell wear.
- Polarized DC Interfacing: Employs rugged, heavy-duty rear connectors to enable safe, foolproof daisy-chain connection of multiple parallel cabinets.

High-Utility Deployment Benefits
- Long-Tail Power Resilience: Delivers an estimated 2 to 4 hours of extended runtime depending on active infrastructure loads, ensuring massive disaster recovery windows.
- Foolproof Technical Integration: Polarized Anderson-style rear connectors eliminate human wiring errors and reverse-polarity hazards during high-voltage system expansion.
- Thermal Protection Infrastructure: The thick metal casing acts as a physical safety barrier, isolating high-density chemical storage from shifting external data room electronics.
Frequently Asked Questions
Can this expansion module be used as a standalone backup power generator?
No. The EP-UPSYABC9A80 is an external battery expansion cabinet and does not contain an AC inverter or primary controller. It must be physically linked to a compatible EVI 10-30kVA three-phase online UPS to supply emergency power to your infrastructure
How does hot-swapping help my data center?
In traditional setups, replacing worn batteries requires taking the entire power backup offline, dropping the security perimeter. The hot-swappable design of this module allows technicians to safely service internal components or swap aging cells while the primary 3-phase UPS continues to run, eliminating operational maintenance downtime.
What is the expected service life of the internal 80 batteries?
Under optimal, climate-controlled server room environments (maintained around 20 to 25 degrees Celsius), the high-grade VRLA batteries have an operational lifespan of 3 to 5 years. Keeping your environment well-ventilated prevents premature cell degradation.
