UPS in the 0-3 kVA range are connected to the load and mains through sockets, which are normally type IEC320. In several markets, they are replaced by connectors adapted to the local needs (Schuko, NEMA, etc.), however, IEC320 C13 or C14 are more frequently used because of their international scope.
Pluggable UPS have a distinctive feature in the use of these sockets versus hardwired UPS. In the most recent generation of new products, these pluggable UPS include programmable sockets (also referred to in technical literature as “load segments”, “programmable receptacles”, “controlled outlets”, etc.). These sockets can be enabled/disabled separately so that the loads connected to them are powered on/off depending on various conditions.
This feature of programmable sockets provides an extra level of control and protection over the secure energy supplied to the load. In addition, there is an extra value in terms of efficiency and energy optimization (especially when used in combination with Advanced ECO mode).
This paper provides some information about the technical points to be taken into consideration (since not every UPS product in the market has the same performance), as well as several application examples about this powerful feature.
