EVI 20000VA 18000W Tower Online 3-Phase UPS (EP-UPS20000Y33OT)

Managing high-capacity data centers, heavy industrial machinery, or critical medical facilities requires uninterrupted power reliability. Voltage dips, frequency fluctuations, and utility blackouts cause costly downtime, data loss, and hardware damage.

The EVI 20000VA / 18000W Tower Online 3-Phase UPS (EP-UPS20000Y33OT) provides mission-critical power protection. Featuring True 3-Phase Input and 3-Phase Output (380V / 400V / 415V), Digital Signal Processing (DSP) control, and 0ms transfer time, this heavy-duty tower UPS completely isolates sensitive infrastructure from grid instability.

Product Features

Three-Phase Online Double-Conversion Design

Continuously converts raw AC utility power to DC power and back to clean, conditioned pure sine wave AC electricity using DSP control. This provides complete electrical isolation to protect heavy industrial loads and sensitive data equipment from high-voltage surges and harmonic distortion.

Zero Transfer Time Operation

Provides immediate switching to battery backup power during grid failures with a 0ms transfer duration, protecting critical equipment against data loss, operational downtime, or system reboots.

N+X Parallel Redundancy Support

Enables parallel installation of multiple UPS units to scale overall system capacity or establish redundant backup power paths, eliminating single points of failure in mission-critical facilities.

High Active Power Efficiency

Featuring a 0.9 power factor, the system maximizes active power output to deliver up to 18000 Watts of continuous operational capacity. Built-in ECO Mode improves overall energy efficiency during periods of stable grid power.

Multi-Function LCD Diagnostic Display

Equipped with an intuitive front-panel LCD screen that delivers real-time system monitoring, including input and output voltages per phase, active load percentage, internal operating temperatures, and battery charge levels.

Flexible System Integration and Management

Includes built-in USB and RS232 communication interfaces alongside dedicated expansion slots for optional SNMP network monitoring cards, parallel communication interface boards, or dry-contact relay outputs.
