1. Product Overview

The GT Tower Series 800–1200kVA tower UPS is a flagship-class, ultra-high-capacity three-phase uninterruptible power supply system developed by GOTTOGPOWER (ANHUI) CO., LTD for hyperscale data centers, national critical infrastructure, and large industrial facilities. Operating on the 3P/3P Online Double Conversion principle with Full DSP digital control over all power conversion stages — rectification, inversion, charging, and discharging — the GT Tower 800–1200kVA large tower UPS delivers industry-leading ≥97% efficiency with rapid dynamic response (<5% load transient; <20ms recovery) at every operating point across its full rated range.

Supporting parallel expansion to a maximum system capacity of 3.2MW, the GT Tower 800–1200kVA UPS is the ideal large-scale tower UPS solution for hyperscale data centers and national infrastructure requiring N+1 redundancy at megawatt scale. Comprehensive three-level protection at system, board, and component levels, combined with intelligent self-diagnosis and large-capacity fault history storage, ensures maximum uptime and minimized MTTR across the complete installation lifecycle.

2. Key Features

• Up to 3.2MW Maximum System Capacity — Hyperscale-Ready Large Tower UPS: Supports parallel expansion to 3.2MW maximum system capacity, making the GT Tower 800–1200kVA the definitive large tower UPS for hyperscale data centers, major financial infrastructure, and national critical power systems requiring megawatt-scale N+1 redundancy.
• ≥97% High-Efficiency Large Three-Phase UPS: Industry-leading ≥97% efficiency at full load reduces energy consumption, cooling infrastructure, and total cost of ownership for 800–1200kVA UPS installations — delivering measurable PUE improvements for data center and industrial facility operators.
• Full DSP Digital Control — Rectification, Inversion, Charging & Discharging: Advanced Full DSP architecture provides simultaneous, precise digital control over all four power conversion stages, enabling superior dynamic performance (<5% load response, <20ms recovery), tight output regulation (±1%), and adaptive battery management.
• Intelligent Self-Diagnosis, Fault Logging & Large-Capacity Historical Data Storage: Comprehensive intelligent self-diagnosis with rich fault event logging and large-capacity historical data storage enables predictive maintenance, rapid root-cause analysis, and minimized MTTR for large-scale mission-critical UPS deployments.
• 10-Inch Color LCD Touchscreen — Enterprise Large UPS Management Interface: Large 10-inch color LCD touchscreen provides real-time visibility of all UPS operational parameters, load profiles, battery status, event logs, and alarm history for efficient on-site large tower UPS management.
• Three-Level Protection — System, Board & Component Reliability: Comprehensive multi-tier protection at system, board, and component levels ensures maximum reliability and enhanced environmental adaptability across the full operational life of the large UPS system.
• Input Derate 100% to 75% — Generator & Weak-Grid Compatible UPS: Maintains 100% rated output with 304–478VAC input, with proportional derating from 100% to 75% as input drops to 228VAC — ensuring reliable large tower UPS operation with both utility grid and diesel generator power under wide disturbance conditions.
