Santak SPU 2kVA Power-Specific Uninterruptible UPS Power Supply 2kVA

Product details

The Santak SPU 2kVA Power-Specific UPS is developed based on over 30 years of industry experience, compliant with DL/T5491-2014 and DL/T1074-2019 standards for the power industry, providing uninterrupted power support for core equipment in scenarios such as power plants and substations. The product supports 220V/110V DC bus input, directly connecting to the power system's DC supply, reducing battery investment and maintenance costs. Its dual-isolation design effectively isolates the grid from the load, protecting equipment from complex power environments like surges and impacts, and is compatible with diverse needs such as IT equipment, nonlinear loads, and impact loads.It operates stably in harsh environments with a wide temperature range of -20℃~55℃, 95% humidity, and high dust. Built-in multiple protection mechanisms for overload, short circuit, and low battery voltage automatically switch to bypass and alarm during faults, ensuring continuous power supply for critical loads in power systems (e.g., DCS, DEH, and microcomputer monitoring systems). Widely used in booster stations, industrial systems, substations, and residential step-down stations, meeting the power assurance needs of power generation groups, grid companies, and enterprise users.
