The GE SitePro (Series 4) 40 kVA is a robust true online double-conversion UPS designed for harsh industrial and mission-critical IT environments. Unlike transformerless systems, the Series 4 features an integrated output isolation transformer, providing complete galvanic isolation and superior protection against dirty power, noise, and grounding issues.
This "Series 4" model is specifically engineered for scalability, supporting GE's exclusive Redundant Parallel Architecture (RPA), allowing you to parallel multiple units for capacity or redundancy. It is ideal for medical imaging, industrial automation, and edge data centers requiring absolute reliability.
RPA™ Technology (Series 4): Parallel units without a single point of failure (decentralized bypass and control).
Heavy-Duty Design: Built to withstand industrial electrical environments and pulsating loads.
Superior Battery Management (SBM): Optimizes charging to maximize battery service life.
Intelligent Energy Management (IEM): Automatically adjusts efficiency based on load levels.
