On-line Double Conversion UPS

The most commonly used power solution in a server room is an on-line double conversion UPS. This is because from a business continuity plan point of view, a on-line UPS includes an automatic bypass and will safely fails to mains power if there is an overload or internal fault. The UPS inverter is also running continuously to provide a digitally generated sinewave output. The next level power solution is a line interactive UPS which may have a sinewave or square-wave output on inverter and a built-in automatic voltage regulation (AVR). Basic UPS protection can be provided for IT peripherals and small loads using a standby / off-line uninterruptible power supply.

Single Phase Power Backup

For longer runtime critical power UPS installations battery extension packs may be an option or the UPS power supply can be installed with a backup power generator.
