EVI 10000VA / 9000W Tower Online Single Phase UPS (EP-UPS10000Y11OT)

EVI 10000VA / 9000W Tower Online Single Phase UPS provides enterprise-grade, continuous power backup designed to safeguard mission-critical IT systems, medical equipment, and telecommunication infrastructure. Utilizing true online double-conversion technology with advanced Digital Signal Processing (DSP) control, this system continuously converts incoming AC power to stable DC and back to clean AC power. This process completely isolates connected devices from voltage sags, power surges, harmonic distortions, and frequency fluctuations while providing zero transfer time (0ms) during mains electrical failures. Designed with a high 0.9 power factor, the unit delivers up to 9000 Watts of real usable power in a space-saving, freestanding tower footprint suitable for enterprise environments without dedicated server racks. Integrated smart energy management features include a High-Efficiency ECO Mode to reduce power consumption, N+X parallel redundancy for scalable power expansion, and direct terminal block connectivity to support high-current enterprise loads.

Product Features

Online Double-Conversion with DSP Control

The system continuously conditions raw utility power into clean, regulated electricity using high-frequency digital signal processing. This ensures total isolation from grid noise and offers continuous protection for sensitive electronics.

Zero Transfer Time Operation

Provides immediate, seamless power transition to battery supply during electrical outages with a 0ms transfer duration, preventing data loss, server resets, or hardware disruption in sensitive equipment.

N+X Parallel Redundancy Support

Enables parallel installation of multiple UPS units to scale overall system capacity or establish backup redundancy, eliminating single points of failure in high-availability data center operations.

High Power Output Efficiency

Featuring a 0.9 output power factor, the system maximizes active power conversion to supply up to 9000 Watts of continuous operational energy. Built-in ECO Mode further improves energy efficiency during stable grid conditions.

What Buyers Look For in Enterprise UPS: 2026 Buying Guide

Selecting a 10kVA UPS requires balancing total load capacity, reliability, and expandability. Customers typically prioritize the following features:

1. Zero Transfer Time (): Traditional line-interactive units take several milliseconds to switch to battery during an outage, which can cause sensitive servers to reboot. Double-conversion technology provides zero transfer time, maintaining steady power flow without interruption.
2. High Real Power Output: Power Factor (PF) determines usable wattage. With a 0.9 PF, the EVI EP-UPS10000Y11OT delivers 9,000 Watts of real usable power from its 10,000VA rating, supporting high-density server racks and motor loads.
3. Clean, Pure Sine Wave: Sensitive IT equipment, medical systems, and audio-visual setups rely on pure sine wave AC power. Harmonics and modified sine waves can overheat power supplies and shorten device lifespans.
4. Generator Compatibility: Regions with unstable electrical grids need a UPS that pairs with diesel or petrol generators. The EVI 10kVA handles wide input frequencies () to filter noisy generator power.
5. N+X Parallel Redundancy: For growing operations, having the option to connect multiple UPS units together ensures load balancing and backup protection if one unit fails.

Key Advantages of the EVI EP-UPS10000Y11OT

• Complete Grid Isolation: Converts AC mains to DC, then back to clean AC output. This completely filters out surges, frequency sags, and harmonic distortions ( input THDi).
• Wide Input Voltage Range (): Keeps the system running on grid power during severe voltage drops without unnecessarily draining internal batteries, extending overall battery lifespan.
• High-Efficiency ECO Mode: Achieves up to 98% efficiency during stable power conditions, significantly reducing utility costs and heat output in air-conditioned server rooms.
• Rotating LCD Interface: Adjusts visually depending on whether the unit is installed vertically or positioned for custom viewing angles.
• Scalable Remote Monitoring: Standard USB and RS232 ports allow local management. Adding an optional SNMP card enables remote web browser monitoring, automated server shut-down scripts, and network alert integration.

EVI 10kVA UPS Applications: Ideal Use Cases & Sizing Guide

• Data Centers & Server Rooms: Keeps multi-host virtualization servers, SAN storage units, and main switchboards powered during utility outages.
• Medical & Laboratory Devices: Protects sensitive MRI controllers, imaging equipment, and analysis instruments from voltage spikes.
• Commercial Office Infrastructure: Runs central CCTV recording arrays, biometric access control points, and PBX telephony setups without delay.
• Industrial Automation: Safeguards Programmable Logic Controllers (PLCs) and automated production lines from sudden power drops that can cause expensive manufacturing resets.
