EVI 10000VA / 9000W 3-Phase Online Double Conversion UPS (EP-UPS10000Y33OT)

The EVI 10000VA / 9000W 3-Phase Online UPS (EP-UPS10000Y33OT) is an industrial-grade power protection system engineered for mission-critical three-phase applications. Utilizing true online double-conversion technology with DSP control, this tower UPS provides zero transfer time, pure sine wave output, and complete isolation from all grid disturbances. With a robust 10000VA/9000W capacity, 3-phase input and output, and support for N+X parallel redundancy, it is the definitive solution for ensuring uninterrupted, clean power in data centers, industrial plants, large medical facilities, and telecom infrastructure. Its wide input voltage range and generator compatibility guarantee reliable operation in even the most unstable power environments.

Product Features

True Online Double-Conversion with DSP Control

This UPS employs pure online double-conversion topology, managed by a Digital Signal Processor (DSP). Incoming three-phase AC power is continuously converted to DC and then inverted back to a perfectly regulated, clean three-phase AC sine wave. This ensures zero transfer time to battery and provides absolute protection against sags, surges, spikes, harmonics, and frequency variations.

High-Capacity Three-Phase Power

With a 10000VA / 9000W capacity and a 0.9 output power factor, this system delivers a full 9kW of usable real power for demanding three-phase loads. It is designed to support large server racks, industrial machinery, medical imaging systems, and other high-power critical infrastructure.

Parallel Redundancy (N+X) for Maximum Uptime

The system supports parallel operation of up to four units. This N+X configuration allows for increased capacity or, more critically, built-in redundancy. If one unit fails, the remaining units seamlessly share the load, eliminating a single point of failure and ensuring continuous power protection for the most vital operations.

Wide Input Voltage and Frequency Tolerance

Engineered for challenging grid conditions, the UPS accepts a wide three-phase input voltage range from approximately 208V to 478V AC. Its broad frequency windows (46-54 Hz for 50Hz, 56-64 Hz for 60Hz) ensure stable operation with unstable mains or when powered by backup generators, providing exceptional adaptability and reliability.

High Efficiency and Generator Compatibility

Operating with high efficiency (typically ~93.5%) and a near-unity input power factor (~0.99), this UPS minimizes energy loss and operational costs. Its wide input tolerances make it fully compatible with backup generators, ensuring a smooth and stable transition during extended utility power failures.

Comprehensive Built-in Protections

The unit includes a full suite of electrical and system protections, including overload, short circuit, over-temperature, and low battery safeguards. These features protect both the UPS itself and the connected critical load from damage.

Scalable Runtime with External Battery Packs

While providing a typical runtime of 10-30 minutes at full load with its internal battery bank, the system is designed to support external battery cabinets. This allows for the runtime to be easily extended to several hours to meet specific operational requirements.
