Santak C3K (G7) Standby UPS 3KVA/3KW

Product details

The seventh-generation Santak Castle Series C3K (G7) Uninterruptible Power Supply builds on 40 years of brand expertise, with a core capacity of 3KVA/3KW. Featuring single-phase input/output, it covers an ultra-wide voltage input range of 110V~300V, adapting to generator and grid fluctuation scenarios. The product includes a built-in 72V battery pack, supports three-stage intelligent charging technology with a maximum charging current of 8A, and integrates temperature/humidity sensors and cloud-link network cards for real-time battery monitoring and remote alerts. The new-generation model adopts CVCF (Constant Voltage Constant Frequency) mode, precisely meeting special equipment voltage requirements, with a wide frequency range of 40~70Hz to handle complex operating conditions.The LCD screen syncs with the "Santak Plus" APP, supporting fault self-recovery, silent mode, and sleep management to minimize manual intervention. The compact design (190×391×297mm) is compatible with rack rail installation, and its IP20 protection rating meets the demanding environmental requirements of enterprise server rooms and production line control systems.
