EVI 10000VA 9000W Tower Online 3 Phase UPS (EP-UPS10000Y33OT)

Operating industrial machinery, heavy-duty server racks, or medical diagnostics requires three-phase electrical stability. Phase imbalances, voltage spikes, and utility power outages risk severe operational downtime and expensive equipment damage.

The EVI 10000VA / 9000W Tower Online 3-Phase UPS (EP-UPS10000Y33OT) delivers industrial-grade power protection. Designed with True 3-Phase Input and 3-Phase Output (380V/400V/415V), Digital Signal Processing (DSP) control, and 0ms transfer time, this tower unit insulates high-draw, mission-critical infrastructure from raw, erratic grid power.

Product Features

Three-Phase Online Double-Conversion Technology

Continuously converts incoming utility power from AC to DC and back to pure sine wave AC electricity using high-frequency digital signal processing. This complete isolation protects heavy three-phase industrial and network loads from high-voltage spikes and harmonic noise.

Zero Transfer Time Operation

Provides an instantaneous transition to battery backup power during electrical grid outages with a 0ms transfer window, preventing operational downtime, equipment resets, or loss of critical data in enterprise environments.

N+X Parallel Redundancy Capability

Supports parallel connections with additional UPS units to either expand total system capacity or establish redundant power configurations, eliminating single points of failure in high-availability installations.

High Output Efficiency and ECO Mode Operation

Utilizes a 0.9 output power factor to deliver up to 9000 Watts of continuous operational energy. Features an integrated High-Efficiency ECO Mode that minimizes energy consumption during periods of stable grid input.

Multi-Function LCD Diagnostic Panel

Includes a multi-function front panel LCD screen providing real-time system performance monitoring, including input/output voltage per phase, percentage of load capacity, temperature levels, and remaining battery runtime.

Integrated Remote Management Capabilities

Equipped with built-in USB and RS232 communication interfaces, along with dedicated expansion slots for optional SNMP network adapter cards, parallel communication cards, or dry-contact relay outputs.
