1. Product Overview

The GT Tower Series 300–600kVA three-phase tower UPS is a large-capacity, high-performance uninterruptible power supply system developed by GOTTOGPOWER (ANHUI) CO., LTD for large enterprise data centers, industrial facilities, financial institutions, and mission-critical national infrastructure requiring robust three-phase online UPS protection at scale. Operating on the 3P/3P Online Double Conversion principle and built around a Full DSP digital control architecture, the GT Tower 300–600kVA three-phase UPS delivers precise, adaptive power conditioning for rectifier, inverter, and battery management across its entire rated power range.

The GT Tower 300–600kVA large UPS system supports 380/400/415V and 50/60Hz power grid systems globally, with a wide input voltage range of 304–478VAC and frequency tolerance of 40–70Hz for reliable operation with both utility grid and diesel generator input. With a ±240VDC battery bus (30–50 batteries, settable), redundancy fan design within the power module, flexible top/bottom cable entry, and a 10-inch LCD touch display, the GT Tower large three-phase UPS is engineered for the highest levels of power infrastructure reliability, maintainability, and deployment flexibility.

2. Key Features

• Full DSP Digital Control — Rectifier, Inverter & Battery Management: Advanced Full DSP (Digital Signal Processor) control architecture delivers flexible, precise, and robust digital management of all three core UPS power conversion stages — enabling superior dynamic response, tighter output regulation, and optimized battery charging across the entire 300–600kVA power range.
• Wide Input Voltage & Frequency Range — Grid & Generator Compatible: The GT Tower 300–600kVA three-phase UPS accepts input voltages from 304–478VAC and frequencies from 40–70Hz, providing reliable uninterruptible power supply operation with both utility grid power and diesel generator input — essential for remote sites, industrial facilities, and data centers with backup generator infrastructure.
• Redundancy Fan Design in Power Module — Enhanced Reliability & Fault Tolerance: Each power module incorporates a redundant fan design, ensuring continued thermal management and full UPS output capability even in the event of an individual fan failure, significantly improving large UPS system reliability and mean time between failures (MTBF).
• Flexible Top/Bottom Cable Entry — Simplified Field Installation: Support for both top and bottom cable entry provides maximum installation flexibility for raised floor, cable tray, and overhead cable management environments, reducing on-site installation complexity and commissioning time for large three-phase UPS deployments.
• Intelligent System Self-Diagnosis & Fault Recording: Comprehensive self-diagnosis engine with rich fault event recording and large-capacity history storage enables proactive UPS maintenance, rapid fault analysis, and minimized mean time to repair (MTTR) for large-scale critical power infrastructure.
• ±3% Voltage Unbalance with 100% Unbalanced Load: The GT Tower UPS maintains output voltage unbalance within ±3% even under 100% unbalanced three-phase loading — ensuring stable power delivery to mixed or asymmetric load configurations typical of large enterprise and industrial environments.
• ≥96% Efficiency — Large-Scale Energy Cost Reduction: High efficiency of ≥96% at full load minimizes cooling requirements and energy costs across large 300–600kVA UPS installations, delivering measurable PUE improvements for data center and industrial facility operators.
