In stock

Three-phase UPS from 10kVA to 500kVA. Reliable and efficient standalone UPS for critical applications. The SG Series is one of the best performing, most reliable and most versatile three-phase UPS systems available to those who need critical power protection.


SG Series IEC Three-phase UPS in BD:

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

The SG Series IEC UPS provides top-class reliability and performance while complying with all relevant EMC and safety standards. ABB’s unique RPA™ technology (redundant parallel architecture) allows units to work in parallel, thus further increasing reliability and uptime. is the best website for you if you are looking for the best Online UPS Supplier in Bangladesh.
