Santak SPU 3kVA Power-Specific Uninterruptible UPS Power Supply 3kVA

Product details

The Santak SPU series 3kVA Power-Specific UPS is built on over 30 years of technical expertise, tailored for critical loads in the power industry. The product complies with DL/T5491-2014 and DL/T1074-2019 power standards, supports input voltage fluctuations of ±25%, and can directly connect to 110V/220V DC bus systems without additional battery configurations. Its dual-isolation design physically separates the grid from the load, with output waveform distortion below 3% and voltage accuracy of ±1%, ensuring stable power supply for precision control systems.Built-in multiple protection mechanisms include low battery shutdown, overload bypass switching, and short-circuit current limiting, with electromagnetic compatibility certified by DL/T1074. It maintains ≥83% conversion efficiency even in wide-temperature environments from -20℃ to 55℃. Particularly suitable for scenarios like DCS control systems in power plants and substation dispatch communication systems, it effectively withstands power surges and other complex conditions, providing 24/7 uninterrupted power for power automation equipment.
