UPS (on-line)

The UPS online (VFI according to IEC 62040-3) with double energy conversion is the most advanced technological solution for power grids with low power quality. This type of UPS is used for reliable protection of equipment and critical systems, including medical equipment, IT equipment, automatic control systems, instrumentation, heating equipment, which are particularly sensitive to power quality.

Online UPSs are the most effective solution due to a number of technical advantages such as:

  • the output voltage and frequency at the output of the UPS are independent of the input network;
  • A pure sine wave at the output of the UPS;
  • 100% protection of the power supply load from all existing electrical interference;
  • maximum wide input voltage range with output voltage adjustment;
  • uninterruptible power supplies of this class, adapted better than others to work with external batteries;
  • Only online UPSs can work in the same system as stand-alone generators.
