Product details
The Santak Castle Series C3K (G7) uninterruptible power supply delivers 3KVA/3KW high-efficiency output, providing round-the-clock power protection for embedded devices and enterprise-level critical systems. Inheriting 40 years of R&D expertise, it features 1.0 power factor technology to significantly enhance load capacity. With an ultra-wide 110-300Vac input voltage range, it adapts to over 90% of grid fluctuation scenarios, ensuring stable operation even during voltage dips or surges. Its exceptional 125% overload endurance for 10 minutes guarantees sufficient time for server clusters, production line control systems, and other critical equipment to complete data backup and safe shutdown during sudden power outages.To meet the specific needs of precision instruments, the CVCF constant voltage and frequency mode delivers precise 220Vac±1% voltage and adaptive 50/60Hz frequency, complemented by a 40-70Hz wide-frequency input design for seamless compatibility with generator power scenarios. The built-in intelligent battery management system supports a maximum 8A fast-charging current, extending the lifespan of the standard 72V/9AH battery pack by 30% through temperature compensation algorithms and periodic self-test programs. Users can flexibly connect devices via four national-standard sockets and terminal blocks, while the standard RS232 interface and optional network monitoring card enable remote management. The Santak Plus APP further offers real-time status tracking and alarm notifications.In terms of user experience, the compact 3U chassis (190x391x297mm) saves 40% installation space, with auto-adjusting fans achieving library-level quietness under low loads. The LCD screen supports multilingual display and wake-on-touch functionality, while the optional EMP temperature-humidity module enables environmental monitoring. The product has obtained CQC energy-saving certification and TÜV Class 1 standards, making it suitable for demanding environments like rail transit communications, medical equipment, and intelligent security systems. It delivers up to 93% utility power conversion efficiency for distributed IT systems, achieving the perfect balance between high performance and low energy consumption.Product Parameters
