N+1 redundancy in an Uninterruptible Power System (UPS) refers to a configuration where there is always an additional or spare UPS module available as a backup in case the main UPS module fails to function. In this configuration, the letter “N” represents a UPS module, while the “+1” indicates an extra or spare UPS module. The N+1 redundancy ensures that the load is supported by a single UPS module, and in the event of its failure, the second UPS module takes over to support the load.
For example, when two UPS systems are connected to a device in an N+1 configuration, if one of the UPS modules fails, the other UPS module will continue to provide power. This redundancy helps minimize downtime and ensures continuous power supply to critical loads.
Please note that this is just one type of redundancy configuration used in UPS systems. There are other configurations such as N, 2N, and N+1×2, each offering different levels of redundancy.
We offer different manufacturers in these configurations and can direct you to a solution that custom fits your needs.
