Online UPS Systems

Online UPS provide the ultimate form of uninterruptible power with a digitally generated sinewave output supply, the ability provide back-up for long duration runtimes and a built-in automatic safe-failure-to mains static bypass arrangement. On line UPS can be single or three phase, with three phase systems generally capable of running in parallel/ redundant N+X configurations for added resilience and scalability.

Related FAQs

  • What is an Online UPS?

    An online UPS is a Voltage and Frequency Independent (VFI) uninterruptible power supply as defined by BS EN 62040. The inverter in an online UPS produces a digitally generated sinewave output, supplied from a DC rectifier supply. The DC rectifier/converter supplies DC power to the inverter from the rectified mains power supply or the connected battery set.

  • How long can an online UPS run on batteries?

    The inverter section of an online uninterruptible power supply is designed for continuous running and the powering of the connected load. This features allows the UPS to be connected to battery extension packs for long runtime applications up to seven hours or more. Some smaller online UPS may be restricted to 4hours on battery at full load in order to protect the inverter electronics from heat damage.

  • What is a double conversion UPS?

    The term ‘double-conversion’ refers to the conversion of mains power supply AC (alternating current) by the rectifier/converter to a DC (direct current) to supply the inverter and charge the battery set. The inverter section to which the load is always connected ‘inverts’ the DC to AC. The AC-DC-AC process is described as ‘double conversion’. There is also a Tripple Conversion mode for some UPS designs covering AC-DC-DC-AC where the DC-DC is a converter.
