Santak SIU 15KVA Industrial UPS Uninterruptible Power Supply 15KVA

Product details

The Santak UPS SIU 15KVA industrial-grade uninterruptible power supply, built on over 30 years of power electronics expertise, is specifically designed to address power fluctuations in industrial scenarios. Featuring a three-phase input/single-phase output or three-phase input/three-phase output voltage system, it supports DC input of 384VDC or 220VDC and is equipped with an output isolation transformer to ensure stable operation of critical equipment like wind power converters and photovoltaic power stations during grid anomalies. Its ultra-wide input voltage range (285VAC-498VAC) and frequency adaptability (45-66Hz) enable it to withstand harsh conditions such as voltage dips in wind farms, high dust, and salt spray corrosion.With PCBA composite coating and redundant design of key components, the device significantly enhances reliability in unmanned scenarios. A 3-year warranty (including batteries) further reduces maintenance costs. The product complies with the "Application Requirements for Uninterruptible Power Supply in Wind Turbines," meeting the Low Voltage Ride Through (LVRT) standard, ensuring wind turbines remain grid-connected for over 625ms during voltage drops to 20% and seamlessly resume operation within 2 seconds of grid recovery. It is widely used in high-reliability sectors such as wind power, photovoltaics, outdoor parcel lockers, and rail transit, providing all-weather power protection for industrial core loads.
