Product Overview
The EVI 20000VA 18000W Tower Online Double Conversion 3-Phase UPS (EP-UPS20000Y33OT) is a flagship ultra-high-capacity power protection system engineered for large-scale data centers, industrial facilities, telecom infrastructure, cloud environments, and mission-critical enterprise operations. Built with advanced online double conversion technology, DSP control, and 3-phase architecture, it delivers continuous, clean, and fully regulated power with zero transfer time for maximum uptime and system reliability.
With its massive 20000VA / 18000W capacity and N+X parallel redundancy support, this UPS is designed for environments that require extreme load handling, scalability, and fault-tolerant power infrastructure.
Performance Powered by Online Double Conversion Technology
The UPS continuously converts incoming AC power to DC and then back to AC, ensuring connected systems always receive pure, stable, and regenerated power regardless of grid instability.
This architecture eliminates transfer time completely during outages, making it ideal for sensitive enterprise and industrial systems that cannot tolerate interruptions.
DSP Control & Intelligent Power Management
Equipped with DSP (Digital Signal Processor) control, the system provides real-time optimization of voltage regulation, waveform stability, and load response.
This ensures highly accurate power delivery, improved efficiency, and stable operation even under rapidly changing or heavy industrial loads.
3-Phase Input & Output Architecture
The UPS supports 3-phase input and output, making it suitable for large industrial and enterprise environments where balanced load distribution and high-capacity power delivery are required.
This improves efficiency, reduces electrical stress, and supports complex infrastructure such as data centers, manufacturing plants, and large IT systems.
N+X Parallel Redundancy System
With N+X parallel redundancy capability, multiple UPS units can be configured to share load or provide backup redundancy.
This ensures maximum system availability, scalability, and fault tolerance for critical operations where downtime is not acceptable.
High-Capacity Load Handling
With a 20000VA / 18000W output rating, the UPS supports extremely heavy-duty loads including enterprise server clusters, storage arrays, industrial automation systems, and large-scale networking infrastructure.
It maintains stable performance even under continuous full-load operation.
Pure Sine Wave Output & Power Conditioning
The UPS delivers a pure sine wave output, ensuring compatibility with sensitive IT and industrial equipment while reducing electrical stress on internal components.
Advanced filtering and power conditioning remove electrical noise and stabilize voltage for clean and consistent power delivery.
Wide Input Range & Generator Compatibility
The system supports a wide input voltage range, allowing stable operation in environments with fluctuating or unstable grid power.
It is also compatible with generator input, ensuring uninterrupted operation during extended outages or backup power transitions.
Tower Design & Industrial Deployment
Designed in a robust tower form factor, the UPS is suitable for industrial facilities, large server rooms, and enterprise environments where rack-mount installation is not required.
Its heavy-duty construction ensures long-term reliability under continuous high-load conditions.
Intelligent Monitoring & Communication
The system includes advanced monitoring through LCD interface and supports RS232, USB, and optional SNMP/network management cards for remote monitoring and centralized control.
This enables real-time system tracking, alerts, and controlled shutdown procedures across enterprise infrastructure.
Battery Management & Reliability
Smart charging technology optimizes battery usage based on load conditions, extending battery lifespan and ensuring consistent backup availability.
This guarantees long-term operational reliability in mission-critical environments.
Protection Features
The UPS provides comprehensive protection against:
Power surges and spikes
Overvoltage and undervoltage conditions
Short circuits and overloads
Frequency instability
These protections safeguard critical infrastructure and minimize risk of downtime or equipment damage.
