Redundant sockets
The number of
outlets connected to the power reserve(battery) provided in the design of the UPS. In order for the UPS to fulfill its main role (providing a backup power in case of power outages), the corresponding electrical appliances must be connected to these outlets. The sockets have a standard shape and are compatible with the vast majority of popular 230 V plugs.
At a minimum, the UPS has
1 or
2 outlets and, in more advanced ones, there may be
3 or
more.
Non-redundant sockets
The number of
outlets without connection to the power reserve provided in the design of the UPS. For devices connected to such outlets, the UPS only performs the function of a surge protector — it smooths out small voltage irregularities; when the mains voltage fails, the power to these outlets is also turned off. The sockets have a standard shape and are compatible with the vast majority of popular 230 V plugs. The presence of sockets without a reserve allows you to connect equipment with different requirements for uninterrupted power supply to one UPS. For example, sockets with a reserve (see above) can include a system unit and a monitor, and a printer can be connected to a socket without a reserve. Thus, if the mains power fails, the computer will continue to work, allowing you to save data, and the printer will turn off, thus saving battery power and providing longer UPS runtime.
Socket type
A socket for a specific type of plug in the UPS design.
—
Type F (Schuko). A traditional European socket with two round holes in the center and grounding contacts in the form of two metal brackets (at the top and bottom of the socket). The term Schuko stuck to this type of socket due to the abbreviation from the German Schutzkontakt - protective contact.
—
Type E (French). The French style socket has two round holes and a protruding ground pin just above them in the center. The standard has become widespread in France, Poland and Belgium (along with the traditional type F sockets).
—
Type G (British). The plug for such sockets consists of two flat horizontal pins and one flat vertical pin for grounding. The standard is found mainly in the countries of the United Kingdom, Malta, Cyprus, Singapore and Hong Kong.
—
Type B (American). American-style sockets are designed for plugs with two flat prongs and a semicircular grounding contact. Type B is widely used in regions with voltage 110 - 127 V - USA, Japan, Saudi Arabia, etc.
Reserved C13/C14 connectors
Number of
C13/C14 connectors with power reserve provided in the UPS design.
Electrical appliances connected to connectors with a reserve are insured against a power failure in the network - in this case they switch to the battery. The C13/C14 connector itself is also known as a “computer socket”; it supplies the same 230 V as a regular household network, but is not compatible with plugs for traditional sockets, because uses three flat contacts. However, there are adapters between these standards.
At a minimum, the UPS is provided with
1,
2 or
3 C13/C14 connectors for one workstation. In more advanced, so to speak office ones, the number of C13/C14 connectors may be greater -
4 ports,
6 connectors,
8 and even more
No reserve C13/C14 connectors
The number of
C13 / C14 connectors without connection to the power reserve, provided in the design of the UPS.
Unlike connectors with a reserve, such connectors do not protect against loss of voltage in the network — for devices connected to them, the UPS only works as a surge protector, smoothing out power surges. This allows you to connect to the UPS devices that do not require continuous power and are not afraid of shutdowns, such as speakers or printers. In the event of a power failure, such devices will not consume battery power, and the UPS will be able to power devices for which continuous power, on the contrary, is essential for longer.
The C13/C14 connector is known colloquially as a "computer socket"; it delivers the same 230 V as a regular household outlet, but is not compatible with conventional plugs, as uses three flat contacts. However, there are adapters between these standards.
