EVI UPS Battery Extension Module Unit for 10kVA Single Phase UPS Product Guide
Comprehensive Product Overview
The EVI UPS Battery Extension Module Unit (Model: EP-UPSYABC9A32) is a heavy-duty, enterprise-grade external battery cabinet engineered to dramatically scale up the backup runtime of 10kVA single-phase online uninterruptible power supplies. While a primary 10kVA UPS provides immediate, zero-transfer-time protection against sudden blackouts, extended corporate operations require hours of ongoing power resilience rather than mere minutes. This expansion module functions as a massive standalone energy reservoir, keeping primary business infrastructure fully active through protracted power grid failures until main utility loops are fully restored.
Inside its rugged enclosure, the module houses a massive array of 32 high-capacity 12V 9Ah sealed lead-acid (SLA) batteries. These cells are configured in a precise series-parallel system architecture to output a matched 240V DC bus feed, which aligns perfectly with the heavy internal charging parameters of compatible EVI 10,000-Watt single-phase online architectures. Because discharging high currents creates intense heat, the module uses ultra-thick internal copper busbars and polarized quick-connect DC wiring to safely distribute enormous blocks of energy without risking thermal overload or electrical resistance bottlenecks.
Designed for flexible physical deployment, the module features a rack/tower ready layout that slips directly into standard 19-inch corporate server racks (occupying a 3U space envelope) or stands vertically alongside tower configurations. It supports modular daisy-chain expansion, allowing system administrators to connect multiple identical battery cabinets in parallel to meet custom enterprise backup targets. It is an essential component for any comprehensive business continuity layout.
Key Features
- Massive Runtime Expansion: Substantially multi-plies the backup duration of compatible 10kVA online power
- High-Density Battery Array: Contains 32 premium, high-capacity 9Ah maintenance-free valve-regulated lead-acid (VRLA) cel
- Flexible 3U Convertible Chassis: Features a versatile rack/tower ready configuration designed to fit cleanly inside 19-inch standard data center racks.
- Hot-Swappable Battery Support: Allows technicians to safely service, test, or replace internal modules without causing downtime to the active server load.
- Polarized Quick-Connect DC Link: Features high-amperage Anderson-style external battery ports on the back panel to prevent dangerous reverse-polarity wiring mistakes.
- Integrated Multi-Level Safety: Outfitted with independent heavy-duty DC circuit breakers and overcurrent fuses to protect the battery bank from short circuits
- Intelligent Charging Balance: Communicates with the host UPS system to allow the main charger to dynamically optimize current control parameters and reduce battery wear.

High-Utility Deployment Benefits
- Long-Duration Autonomy: Provides a typical runtime extension of 45 to 90 minutes under common network loads, giving ample time for generator engagement.
- Scalable Core Power: The modular daisy-chain engineering enables administrators to pile multiple battery blocks together for continuous multi-hour backup loops.
- Physical Protection Infrastructure: The thick metal casing acts as a thermal barrier, safeguarding the internal lead-acid cells from shifting ambient datacenter dynamics
Frequently Asked Questions
Can this battery extension module operate as a standalone emergency backup?
No, the EP-UPSYABC9A32 is an external battery expansion cabinet and does not contain an internal inverter or charger module. It must be plugged into a compatible 10kVA single-phase online UPS to distribute power during structural outages.
What is the average operational lifespan of the internal 9Ah cells?
Under recommended ambient computer room temperatures (typically around 25 degrees Celsius), the high-grade VRLA batteries have an expected service life of 3 to 5 years. Keeping the server racks well-ventilated prevents early capacity degradation.
Is separate software needed to manage this expansion cabinet?
No, the charging and diagnostic lifecycle parameters are handled directly by the microprocessors inside the host 10kVA online UPS. Once the physical DC quick-connect interface is locked into place, the primary UPS automatically balances its charger output
