Uninterruptible power supply n1 configuration

What is a n+1 ups configuration?

The N stands for a UPS module while +1 stands for an additional or spare UPS module. Due to this, an N+1 UPS configuration has at least two UPS modules connected to a device. For computer servers requiring six UPS modules, an N+1 UPS configuration means the system will have a total of seven UPS devices for use.

Should a data center use a n+1 UPS system?

For instance, if a data center needs three UPS units to handle its load, an N+1 configuration would involve installing a fourth UPS unit as a backup. This ensures that if one UPS unit fails, the others can still maintain power supply to the essential equipment.

What is an uninterruptible power supply (UPS)?

An uninterruptible power supply (UPS) is mainly used to ensure computers continue to function when the main source of power goes out. A UPS allows users to shut down computer properly to ensure critical information is protected. These devices are also essential for computer servers, especially those used for businesses.

What happens if a n+1 ups module fails?

In an N+1 UPS configuration, as shown below, two or more UPS systems deliver power to the critical parallel bus, which feeds the critical load. A failure in one UPS module would allow the UPS to remove itself from the critical bus, while the remaining module (or modules) supports the critical load.
