1. Product Overview

The GTM-50 Series 50–600kVA modular UPS is a high-power, high-efficiency uninterruptible power supply system developed by GOTTOGPOWER (ANHUI) CO., LTD. Designed for large-scale data center UPS, industrial UPS, and enterprise power protection applications, the GTM-50 Series modular UPS supports online double-conversion (3P/3P) operation across a scalable power range from 50kVA to 600kVA. With a best-in-class efficiency rating of ≥97%, the GTM-50 modular UPS system significantly reduces energy consumption and total cost of ownership compared to conventional UPS solutions.

As a true modular UPS power system, the GTM-50 Series allows capacity expansion without downtime, making it the ideal three-phase UPS solution for mission-critical environments requiring N+1 redundancy, scalable power infrastructure, and long-term investment protection. The GTM-50 Series online UPS is fully compatible with lithium battery UPS configurations, featuring an optional battery neutral-free design that future-proofs your power system for next-generation energy storage.

2. Key Features

• High Power Density Modular UPS: Saves over 10% installation space compared to similar UPS products, enabling more efficient data center power density management and rack space optimization.
• Lithium Battery UPS Compatible: Optional battery neutral-free design ensures seamless compatibility with lithium battery UPS systems, reducing battery cabinet footprint and total weight.
• Ultimate Reliability — System, Board & Component Protection: Comprehensive three-level protection architecture (system, board, and component) delivers the highest modular UPS reliability for critical power infrastructure.
• Large LCD Touch Screen UPS Interface: Color graphical LCD touch screen (7-inch on GTM200/50; 10-inch on GTM300–600/50) provides intuitive UPS monitoring, real-time load management, and user-friendly configuration.
• Highly Integrated PCB Design: Optimized PCB integration improves UPS module assemblability, lowers manufacturing variance, and reduces field maintenance human error.
• Fault-Tolerant Thermal Management: Optimized UPS thermal layout with elevated design margin — the modular UPS system continues to support up to 70% load output even in the event of a single fan failure, ensuring uninterrupted power supply.
• ≥97% UPS Efficiency: Industry-leading online UPS efficiency rating of ≥97% minimizes heat dissipation and lowers total operating cost for large-scale UPS installations.
