Santak UPS Power Supply 50KVA Santak SIU 50KVA Industrial UPS Uninterruptible Power Supply
The Santak UPS SIU 50KVA industrial-grade uninterruptible power supply is specifically designed for harsh industrial environments, featuring an ultra-wide operating temperature range of -25℃ to 60℃ and high-altitude adaptability up to 4000 meters. Its core triple-protection coating technology effectively resists salt spray, mold, and moisture erosion. The product fully complies with the low-voltage ride-through (LVRT) standards of the wind power industry, capable of sustaining power supply for over 625ms even when grid voltage drops to 20%. Equipped with redundant circuit design and a 384VDC direct battery connection system, it ensures stable operation of converter control systems during voltage dips.It supports three-phase input/output voltage configuration and ±1% precision voltage stabilization, with an ultra-wide input range of 285-498VAC to handle grid fluctuations in wind power scenarios. Its 110%-150% overload capacity provides a safety buffer for outdoor smart terminal cabinets, photovoltaic power stations, and similar applications. The entire unit is certified by TLC/CE/CQC and comes with a standard 3-year full warranty including batteries. The intelligent self-management function in unattended mode significantly reduces maintenance costs.

Product details
The Santak SIU 50KVA industrial UPS embodies 30 years of power electronics expertise, specifically designed to meet the stringent power demands of renewable energy scenarios such as wind and solar. In wind power systems, when grid voltage suddenly drops or a disconnection occurs, this equipment provides uninterrupted power support to pitch control systems with 0ms battery switching speed and ±0.05Hz output frequency accuracy, fully complying with the LVRT capability requirements of the GB/T 19963-2021 wind farm grid connection standard.Its ultra-wide input voltage range of 285-498VAC adapts to severe grid fluctuations in wind farms. Critical circuit boards are coated with military-grade conformal coating, combined with IP42 protection rating, ensuring stable operation in extreme temperatures from -25℃ to 60℃, effectively addressing high salt spray corrosion in offshore wind farms and sandstorm impacts in desert photovoltaic plants. The device features an intelligent battery management system, supports 384VDC direct battery connection and dual redundant design, paired with an output isolation transformer, enabling full-load operation even at 4000-meter high-altitude regions.For scenarios such as outdoor parcel lockers and rail transit, an optional dry contact monitoring card enables remote operation and maintenance, while a 6-pulse + 5th harmonic filter keeps input current distortion rate below 10%, significantly reducing harmonic pollution to the grid. As an industrial-grade power solution certified by both CE and TLC, the SIU series offers a 3-year full-machine warranty, building a solid power defense for various critical loads.Product Features
