INFINITE UPS is AEC’s 480 V modular three-phase, double-conversion online UPS series, available in power ratings from 80 kVA to 1200 kVA.
The system is built on 100 kW hot-swappable power modules, installed in 100 kW+1 and 200 kW+1 frames, supporting scalable capacity expansion up to 1200 kVA with N+X redundancy.
INFINITE integrates Silicon Carbide (SiC)–based PFC technology combined with a 3-level IGBT inverter topology, delivering up to 97.3% efficiency, positioning it among the highest efficiency modular UPS systems in the industry. The system provides true online double conversion with a unity (1.0) output power factor.
The UPS features a 3-breaker design, a wide DC operating range, and full compatibility with AEC’s modular lithium battery cabinets, enabling a high power-density solution with optimized UPS + lithium footprint.
This architecture allows module-level serviceability without load interruption, supporting mission-critical applications requiring scalability, efficiency, and high availability.
