UPS…useful information

UPS…useful information

Michael Alhadeff

A UPS protects your computers, important equipment and all other devices you have plugged into it from four different power problems:

  • voltage surges and spikes (where voltage is greater than it should be)
  • voltage sags (voltage is less than it should be)
  • total power failure.
  • frequency differences (when the power is flowing at something other than 50 Hertz)

There are three types of UPS’s:

  • online double-conversion: the inverter constantly supplies a regulated voltage to the load and therefore transfer times are zero.
    This is the safest but most expensive power protection.
  • line-interactive: Similar to a standby UPS but includes a variable-voltage auto-transformer
  • offline/standby: Basic features, providing surge protection and battery backup, which is more for a small business or your home.

The UPS was not invented by one particular person but is the culmination of a lot of different theories and studies.

The most common reason for UPS failures is their batteries. Consistent battery maintenance is required.

The lifespan of UPS batteries depends on many conditions:

  • environmental conditions
  • power quality
  • number of discharges
  • other batteries connected in the series

Three-phase UPS’s use either standard UPS batteries which are usually used in legacy units or plug-in-play batteries.

Standard batteries are difficult to change and require a manual testing procedure.

Plug-in-play batteries are automatically tested by the UPS and are designed for easier changing.
