Monoblock Uninterruptible Power Supplies - 3 phases


Key Features

The SG Series is one of the best performing, most reliable and versatile three-phase UPS systems available for those who need critical power protection. Power convenience is guaranteed for a wide variety of applications with a low total cost of ownership (TCO).

This true online double conversion UPS leverages network integration software and communication connectivity to provide comprehensive, easy-to-integrate power protection for virtually any IT environment. The SG Series operates in VFI (independent of voltage frequency) mode that maximizes load protection at any time. Instead of standard filters, the UPS runs an innovative control algorithm on the IGBT rectifier to ensure the most efficient transmission of clean power.


The SG Series UPS provides first-class reliability and performance while complying with all relevant EMC and safety standards. ABB's unique RPA ™ technology (redundant parallel architecture) enables units to operate in parallel, further increasing reliability and uptime.
