UPS for medium-sized and large critical installations

NextEnergy NXE is a modern online UPS series for data centers, ICT centers, industry, and larger buildings. The series provides high efficiency, flexible installation, and scalable capacity for critical loads. "Active Filter Mode” provides tolerance for voltage variation up to ±20% which is far better than ±10% which is permitted in the power grid.

Typical setup

• UPS unit with power from 250 to 800 kVA
• Tower cabinet with front-to-top ventilation and full front access for service
• Battery panel or battery bank adapted to load and autonomy
• Monitoring of load, batteries, and system status via graphical color display
• Some models support cable entry from top or bottom, depending on installation requirements.
• Parallel connection of multiple units for higher capacity or redundancy

The setup covers needs in data centers, ICT centers, industry, and critical technical installations.
