PRODUCT OVERVIEW

ABB External Battery Module 11RT G2 3 kVA

The ABB External Battery Module 11RT G2 3 kVA (part number 4NWP100205R0001) is a dedicated external battery extension unit designed to work with the ABB PowerValue 11RT G2 3 kVA UPS series. It expands the UPS’s available energy reserves to provide significantly longer backup runtime during mains power interruptions, enhancing business continuity for critical systems such as servers, networking gear, telecom equipment, and access control systems. This battery module is an accessory intended for single‑phase UPS applications and complements the internal battery system.

Battery Configuration and Energy Storage

The External Battery Module incorporates 8 sealed lead‑acid (SLA) batteries, each rated at 9.4 Ah and 12 V, assembled to match the UPS’s battery string requirements. These batteries are contained within a robust external cabinet, supplying additional stored energy that the UPS can draw on during outages. This configuration extends backup duration in proportion to connected load and allows for multiple modules to be added in series for even greater runtime flexibility.

Runtime Performance and Scalability

With the External Battery Module installed on a PowerValue 11RT G2 3 kVA UPS, typical runtime at full load increases from about 13 minutes (with internal batteries only) to roughly 51 minutes with one additional module connected, and further runtime extension when multiple modules are added in parallel. Runtime scales progressively — for example, two modules can yield around 91 minutes, three modules around 133 minutes, and four modules around 173 minutes of backup power at full load — making it suitable for mission‑critical applications where longer support time is essential.

Compatibility, Certifications, and Use Case

The 4NWP100205R0001 module is specifically engineered for ABB PowerValue 11RT G2 3 kVA UPS models (including both “B” and “S” variants) and is classified as an UPS battery accessory (not a standalone UPS). It supports the UPS charging circuitry and adheres to safety and environmental compliance frameworks, including RoHS, CE, and REACH declarations in applicable regions. This accessory is ideal for installations requiring extended runtime without upsizing the UPS, such as data communications closets, small server racks, and critical infrastructure in SMB or enterprise branches.
