How does an industrial UPS compare to a commercial UPS?

Commercial UPS are designed for server room and datacentre installations which tend to be relatively clean and have a temperature managed environment. The UPS may be transformerless or transformer-based. The latter offers Galvanic isolation which can make the UPS more robust for use in industrial applications, as well as IT applications in more remote areas. UPS systems designed specifically for industrial applications have greater levels of redundancy in their architecture, can be customised to operate within wider temperature ranges (-10 to +55°C), higher humidity levels, dusty and corrosive gas environments and be made to withstand vibrations including seismic shocks and may use older 12-pulse thyristor-based rectifiers instead of the more modern IGBT (integrated gate bipolar transistors) rectifiers found in commercial UPS systems.
