TM66E Modular 3:3 UPS Series
10 kVA to 1.2 MW
The ATENCO TM66E modular three-phase UPS series covers 10 kVA to 1.2 MW across four transformer-less online double-conversion platforms tailored to project scale: TM66E Compact Modular 30–75 kVA with built-in hot-swappable VRLA battery modules, TM66E Modular 10–150 kVA with 10–30 kVA hot-swappable power modules and external battery system, TM66E Modular 40–600 kVA with 40 / 50 / 60 kVA modules and VRLA / lithium battery support, and TM66E Large Modular 400 kVA to 1.2 MW with 100 kVA modules, HECO mode and lifecycle management. All platforms provide output PF 1.0, N+X redundancy and LBS synchronization by configuration.
Four TM66E Modular Three-Phase UPS Platforms
TM66E is organized into four transformer-less modular three-phase UPS platforms covering 10 kVA to 1.2 MW. Each platform is differentiated by cabinet architecture, power-module size, battery configuration, charger capacity, efficiency mode and parallel design, so the correct TM66E system can be matched to project capacity, redundancy plan, footprint and energy-saving target.
