Santak 3C3 HD-300K three-phase online UPS power supply 300KVA/300KW

Product details

The Santak Castle 3C3 HD-300K, as a new-generation intelligent power solution, redefines the application standards for high-power UPS through technological innovation. This 300KVA/300KW uninterruptible power supply employs dual-core technology combining power electronics and digital signal control, achieving an ultra-high input power factor of 0.99 within a wide voltage input range of 240-478V, effectively reducing grid harmonic pollution. Its revolutionary I-type three-level circuit design, paired with oil-immersed long-life capacitors, enables the unit to achieve an online operating efficiency of 97%, with ECO mode pushing the energy efficiency limit beyond 99%, saving enterprises tens of thousands of yuan in electricity costs annually.The device is equipped with an intelligent battery management system that supports multiple energy storage solutions including lead-acid, gel, nickel-cadmium, and lithium batteries. Its 400A high-current fast charging technology can recharge 80% of the battery capacity within 2 hours, making it particularly suitable for scenarios requiring rapid power recovery, such as hospital operating rooms and data center server rooms. The modular architecture design reduces critical component replacement time to within 30 minutes, and combined with a pure sine wave output at a 1.0 power factor, it can support an additional 10% load of precision equipment such as servers and monitoring instruments. The 7-inch full-color touchscreen displays 28 real-time parameters including input/output voltage and load rate, providing intuitive control over the device's operational status.In demanding environments such as rail transit control centers and 5G base station core rooms, the Santak 3C3 HD-300K demonstrates exceptional adaptability: it supports wide-temperature storage from -15°C to 55°C, flexible configuration of up to 40 battery units, and four-unit parallel operation to achieve a 1200KVA expansion capacity. Its unique anti-condensation design and 1000-meter altitude operation without derating ensure 7×24 uninterrupted power supply for critical scenarios like financial systems and automated production lines. From adaptive frequency regulation (42-70Hz) at the input to <3% waveform distortion at the output, every detail is meticulously crafted to protect precision medical equipment and industrial control systems, truly achieving zero compromise in power protection.
