EVI 40000VA / 36000W 3-Phase Tower Online UPS – N+X Redundancy & Fully Digital Control (EP-UPS40Y33OT)

The EVI 40000VA / 36000W 3-Phase Tower Online UPS is a powerful enterprise-grade online UPS solution engineered to deliver reliable and continuous power protection for large-scale data centers, industrial systems, telecom infrastructure, heavy-duty servers, and other critical three-phase applications.

With an impressive 40,000VA / 36,000W capacity, this UPS is designed to handle demanding power loads while maintaining stable and efficient power distribution across connected equipment.

Its 3-phase input and output configuration ensures balanced performance and optimized energy delivery for high-capacity operations.

Built with advanced online double-conversion technology and DSP digital control, the UPS continuously delivers clean and highly regulated sine-wave output while isolating sensitive equipment from surges, spikes, voltage sags, harmonics, and unstable grid conditions.

The system provides zero transfer time, ensuring seamless operation without interruption whenever utility power fails or fluctuates.

For enhanced reliability and scalability, the UPS supports N+X parallel redundancy, allowing up to four units to operate in parallel for increased capacity and backup redundancy in mission-critical environments.

With a high output power factor of 0.9, the UPS maximizes usable power delivery for connected systems while improving operational efficiency. It also supports a wide input voltage range of 208–478Vac and a frequency range of 40–70Hz, making it highly resilient in unstable power environments and compatible with generator systems.

The UPS includes built-in batteries for immediate backup support and also allows connection of external battery packs for extended runtime during prolonged outages.

To improve efficiency and battery longevity, the UPS features an energy-saving ECO mode and intelligent charging management system that optimizes charging performance while reducing unnecessary power consumption.

The integrated 7-inch touch LCD display provides clear real-time monitoring of system performance, including voltage levels, battery status, load conditions, alarms, and diagnostics for simplified management and control.

For advanced connectivity and monitoring, the UPS includes multiple communication interfaces such as USB, RS232, RS485, parallel ports, and dry-contact ports, with optional SNMP and relay card support for remote monitoring and integration with facility management systems.

Additional safety features such as Emergency Power-Off (EPO) and fully digital rectifier, charger, and inverter control ensure dependable performance, operational safety, and long-term reliability in critical environments.
