Product details
As a flagship product in the field of power protection, the Santak Castle 3C3 HD-400K perfectly combines its massive 400KVA/400KW power capacity with intelligent operation and maintenance. This UPS features military-grade IGBT modules and an optimized three-level circuit architecture, maintaining 97% online operation efficiency while boosting energy efficiency to 99% in ECO mode, achieving a dual breakthrough in power supply and energy conservation. Its 1.0 output power factor design enhances load capacity by 10% compared to conventional equipment, enabling a single unit to support core server racks in large data centers or full life-support systems in top-tier hospital operating rooms.In extreme power environments, the built-in intelligent detection system automatically switches to 480V battery power supply. The 280A ultra-fast charging technology can restore 80% of energy storage within 30 minutes, combined with oil-immersed maintenance-free capacitor design, completely eliminating the pain point of frequent part replacements in traditional equipment. A 7-inch industrial-grade touchscreen displays real-time input/output voltage, load rate, and battery health status. Maintenance personnel can complete parallel setup for four devices via the visual interface, making it particularly suitable for 5G base station group power supply or smart manufacturing production line power expansion needs.The modular construction design reduces critical component replacement time to under 30 minutes, supporting stable operation in a wide temperature range of -15℃ to 55℃ and 95% humidity environments. From real-time transaction data protection in banking and financial systems to power backup for rail transit dispatch centers, the 3C3 HD-400K, with its dual certification quality compliant with GB4943 and IEC62040-2 standards, has become the preferred power safety solution for critical sectors such as healthcare, education, and telecommunications.Product Features
