Product Overview
The EVI 40000VA 36000W Tower Online Double Conversion 3-Phase UPS (EP-UPS40Y33OT) is a flagship ultra-high-capacity power protection system engineered for hyperscale data centers, industrial plants, telecom backbone infrastructure, and mission-critical enterprise environments. Built with advanced online double conversion technology, DSP (Digital Signal Processing) control, and N+X parallel redundancy, it delivers continuous, clean, and fully regulated power with zero transfer time, ensuring maximum uptime and system reliability.
With its massive 40000VA / 36000W capacity, this UPS is designed for extreme-load environments including large server farms, cloud computing infrastructure, industrial automation systems, and high-density enterprise networks where uninterrupted power is essential.
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 all transfer delays during outages, making it suitable for highly sensitive and mission-critical systems that require uninterrupted operation at all times.
DSP (Digital Signal Processing) Control & Intelligent Regulation
Equipped with DSP control, the system provides real-time digital management of voltage regulation, waveform stability, and load response.
This ensures high-precision power output, improved efficiency, and stable performance even under rapidly changing or heavy industrial load conditions.
3-Phase Input & Output Architecture
The UPS supports 3-phase input and output, making it ideal for industrial-scale deployments where balanced power distribution and high-capacity energy handling are required.
This configuration improves efficiency, reduces electrical stress, and supports complex infrastructures such as data centers, manufacturing facilities, and enterprise IT systems.
N+X Parallel Redundancy System
With N+X parallel redundancy capability, multiple UPS units can be connected to increase capacity or provide backup redundancy.
This ensures maximum system availability, scalability, and fault tolerance for environments where downtime is not acceptable.
High-Capacity Load Handling
With a 40000VA / 36000W output capacity, the system supports extremely demanding workloads including hyperscale server clusters, storage arrays, industrial machinery, and large-scale networking systems.
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 full compatibility with sensitive IT and industrial equipment while reducing electrical stress on connected devices.
Advanced filtering and conditioning remove electrical noise and stabilize voltage for clean, reliable power delivery.
Wide Input Range & Generator Compatibility
The system supports a wide input voltage range, allowing stable operation in environments with fluctuating or unstable utility power.
It is also compatible with generator input, ensuring continuous operation during extended outages or backup power transitions.
Tower Design & Industrial Deployment
Designed in a robust tower form factor, the UPS is suitable for hyperscale facilities, industrial environments, and enterprise infrastructure where rack mounting is not required.
Its heavy-duty construction ensures long-term reliability under continuous high-load operation.
Intelligent Monitoring & Communication
The system includes LCD-based monitoring and supports RS232, USB, and optional SNMP/network management cards for remote monitoring and centralized control.
This enables real-time system diagnostics, alerts, and controlled shutdown procedures across large-scale infrastructure.
Battery Management & Reliability
Smart charging technology optimizes battery performance 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 safeguards ensure maximum protection for hyperscale infrastructure and minimize downtime risk.
