Santak SIU 50KVA Industrial UPS Uninterruptible Power Supply 50KVA

Product details

Leveraging over 30 years of technical expertise, the Santak SIU 50KVA Industrial UPS is optimized for renewable energy sectors like wind and solar power, addressing challenges such as poor grid quality, significant temperature fluctuations, and high dust levels. The product operates in an ultra-wide temperature range of -25°C to 60°C, with key components featuring redundant designs and triple-proof coating for effective moisture, salt fog, and mold resistance, adapting to 4000-meter high-altitude and harsh grid fluctuation environments.Equipped with a standard output isolation transformer and optional input transformer, it offers a dual-isolation safety solution to ensure continuous power supply for converters and control systems during voltage dips, meeting national Low Voltage Ride Through (LVRT) standards for wind turbines. Its high-efficiency design and wide input voltage range (285VAC-498VAC) ensure reliable operation in outdoor express cabinets, smart terminal cabinets, rail transit, and other scenarios. A 3-year whole-machine warranty and unmanned self-management features further reduce maintenance costs, providing industrial users with professional power protection.
