Santak SIU 15KVA Industrial UPS Uninterruptible Power Supply 15KVA

Product details

The Santak SIU 15KVA industrial UPS integrates 30 years of power electronics R&D experience, specifically designed to address power interruption risks in scenarios like renewable energy generation and smart outdoor equipment. In wind power applications, the device handles severe grid fluctuations with a 285VAC-498VAC ultra-wide input voltage range, maintaining 625ms continuous power supply even during 20% voltage dips, precisely meeting LVRT requirements in the 'Technical Regulations for Wind Farm Integration into Power Systems'.Its core advantage lies in harsh environment adaptability: PCBA components coated with triple-proof lacquer withstand 95% humidity and salt fog corrosion, supporting storage temperatures from -40°C to 60°C while maintaining full-power operation even at 4,000-meter high-altitude wind farms. The equipment features a 6-pulse + 5th harmonic filter reducing input harmonics below 10%, coupled with ±1% output voltage accuracy to deliver clean power for converter control systems. The three-phase input/output architecture supports 380V±1% three-phase output, with 150% overload capacity for 1 minute, and built-in output isolation transformers ensure safety for sensitive equipment.Designed for unmanned scenarios, its self-management function enables remote monitoring via dry contact cards, paired with a 384VDC battery pack for 0ms switching. Currently, this series has been successfully applied in photovoltaic station smart combiner boxes, outdoor energy storage systems, and rail transit signal stations, accumulating over 100,000 fault-free operating hours in high-risk industries like steel and petrochemicals. Technical parameters deeply align with industrial needs: input frequency adapts to grid fluctuations at 45-66Hz, output crest factor ratio of 3:1 ensures stable inductive loads, and a 12-pulse design reduces energy consumption while maintaining ≥0.82 power factor.Users can optionally configure 220V/384VDC battery topology, with a dual-transformer isolation solution providing double protection for high-dust workshops, truly achieving industrial-grade 365-day uninterrupted protection.
