Modular UPS Power Supply Series: High-Efficiency, Scalable Uninterruptible Power Solutions for Critical Infrastructure The Modular UPS Power Supply Series represents a next-generation approach to reliable power protection, especially tailored for large and medium-sized data centers, enterprise buildings, and mission-critical facilities. At its core lies the 40KVA power module—an intelligent, high-performance component designed for seamless scalability, operational resilience, and energy efficiency. This series integrates advanced digital control technology with modular architecture, enabling businesses to future-proof their infrastructure while minimizing downtime risks. Key Features That Set It Apart This modular uninterruptible power system delivers unmatched performance through full digital signal processing (DSP), ensuring precise regulation of rectification, inversion, battery charging, and load management. With an input power factor reaching 0.99 and total system efficiency exceeding 96%, it significantly reduces electrical losses compared to traditional designs. The unit supports hot-swappable modules—allowing real-time maintenance without service interruption—and features a robust three-stage battery charge/discharge algorithm compatible with both lead-acid and lithium iron phosphate (LiFePO4) batteries. Its intelligent self-diagnosis capability stores extensive fault logs and historical data, empowering proactive monitoring via a large LCD touch screen interface. Additionally, the system offers ultra-fast transfer times (0ms), dynamic voltage transient suppression (<3%), and superior overload handling (up to 150% for 1 minute), making it ideal for environments where uptime is non-negotiable. Technical Excellence in Every Detail Each 40KVA module operates in pure online double conversion mode, delivering clean, stable output under varying input conditions—from 291V to 492V line-to-line at full load. The system maintains exceptional harmonic distortion levels (THDi < 3%, THDu < 2% under linear loads), ensuring compatibility with sensitive IT equipment. Designed for flexibility, the modular configuration allows users to scale capacity from 40KVA up to 520KVA by adding or removing units within a single rack. Battery configurations support 30–50 cells per set, with customizable voltage ranges (+/- 240VDC), enabling tailored solutions for diverse applications. Environmental adaptability includes operation across temperatures from -10°C to +40°C and humidity levels up to 98%, with IP30-rated enclosures for dust resistance. Ideal Applications Across Industries From server rooms and telecommunications hubs to industrial automation systems and healthcare facilities, this modular UPS serves as a dependable backbone for continuous operations. Whether deployed in a small-scale facility requiring just three 40KVA modules or a high-density data center needing thirteen, the system adapts effortlessly. Its ability to handle sudden load spikes, maintain consistent output frequency (50/60Hz ±0.01Hz), and provide instantaneous failover between mains, inverter, and bypass modes ensures uninterrupted power during outages or grid fluctuations. User Feedback Highlights Reliability and Ease of Use Customers consistently praise the system’s intuitive interface, which simplifies daily oversight and troubleshooting. Many highlight how the intelligent sleep mode reduces energy consumption during low-load periods—a key advantage for green energy initiatives. Maintenance staff appreciate the ease of replacing individual modules without shutting down the entire system, reducing mean time to repair (MTTR). The inclusion of standard communication interfaces like RS232, RS485, dry contacts, and optional SNMP cards further enhances integration into existing network management platforms. Frequently Asked Questions What makes this UPS different from conventional units? Unlike fixed-capacity systems, the modular design allows incremental expansion based on evolving needs, improving capital efficiency and minimizing waste. Can I use LiFePO4 batteries with this system? Yes—the system supports both sealed lead-acid and lithium iron phosphate battery technologies, offering extended lifespan and reduced environmental impact. How does the hot-swap feature benefit me? It enables live replacement of faulty components, eliminating unplanned downtime and enhancing overall system availability. Is it suitable for international deployment? Absolutely—it meets global standards for electromagnetic compatibility, thermal performance, and safety, making it appropriate for use worldwide outside China, Hong Kong, Macau, and Taiwan. This modular power solution combines cutting-edge engineering with practical usability, offering enterprises a scalable, efficient, and resilient foundation for modern power demands.
