Santak SIU 30KVA Industrial UPS Uninterruptible Power Supply 30KVA

Product details

With 30 years of power electronics expertise, the Santak SIU 30KVA industrial UPS redefines industrial power protection standards. This power system customized for the wind power industry can sustain over 625ms of continuous power supply even when voltage drops to 20%, fully complying with the stringent requirements of the 'Technical Requirements for Wind Farms Connecting to the Power System'.With its ultra-wide input voltage range of 285-498VAC and ±1% output accuracy, it effortlessly handles severe grid fluctuations in wind farms. Capable of operating in temperatures from -25℃ to 60℃ and featuring PCBA core components coated with conformal paint, it maintains stable performance in salt spray, mold, and high-dust environments. Field-tested and validated for altitudes up to 4000 meters (no derating required below 2000 meters), it provides a reliable defense for wind turbine pitch control systems. In wind power converter protection scenarios, the product adopts a battery-direct-to-DC-bus technology, achieving 0ms grid switching and sustaining 110%-150% overload capacity for 1-10 minutes.Equipped with an output isolation transformer and optional dual-isolation input solutions, it effectively mitigates electromagnetic interference risks. For unmanned wind farms, it supports dry contact card remote management and pairs with self-diagnostic functions for 24/7 intelligent operation and maintenance. Its 384VDC DC input is compatible with photovoltaic energy storage systems, while flexible single/three-phase output modes adapt to 380V/400V/415V multi-standard grids. Output harmonics are controlled within EN62040-3 standards, with a crest factor ratio better than 0.125, ensuring pure power supply for precision equipment. The product has successfully expanded to over 20 applications, including photovoltaic power stations, outdoor smart cabinets, and rail transit.In extreme storage conditions of -40℃ or high-temperature operations at 60℃, redundant design and ample margin of key components ensure 100,000 hours of fault-free operation. The 12-pulse rectification technology reduces input harmonics to below 10% and increases power factor to 0.92, achieving over 95% operational efficiency with CQC energy-saving certification. Currently offering three-in-three-out and three-in-single-out dual-voltage configurations, with power coverage from 10-200KVA, it comes standard with a 3-year full-machine warranty, building a full-lifecycle power safety barrier for industrial users.
