ELS Modular Online UPS (30 - 300kVA)

ELSIPOWER 30–300 kVA three-phase modular online UPS uses a three-level inverter and DSP control for high input power factor and low harmonics. With 2U 30 kVA modules it reaches 300 kVA in one cabinet and up to 900 kVA in parallel within less than 2 m², while N+X redundancy and hot-swappable modules protect data centers reliably.

N+X Modular Redundancy: Hot-swappable power and bypass modules allow maintenance without load interruption.
High Power Density: 30 kVA power modules in 2U; up to 300 kVA in one cabinet.
Parallel Expansion: Scalable architecture up to 900 kVA within less than 2 m².
DSP & IGBT Technology: Three-level inverter for stable, high-performance operation and a wide input range.
