Businesses are starting to see the importance of ensuring their uninterruptible power supply devices have a back up to protect important information. As the use of N+1 configuration for a UPS system starts to increase, it is become important for businesses to select the best one suitable for their needs. Aside from the isolated redundant configuration and parallel redundant configuration, businesses also have the option to use an internally “modular” redundant configuration for their UPS system.
An internally modular redundant configuration or setup uses only one battery for all its UPS modules. If any of the modules fail to operate properly, the other modules will act as backup. This will ensure the equipment connected to the system will continue to receive power. This setup is the most basic type of N+1 UPS configuration. Aside from using just one battery, all of the UPS modules also share one output.
In this configuration, the load is shared by all of the modules up. The capacity of this set up can be increased with the addition of more modules. But, one major disadvantage of this configuration is the single battery it uses. If the battery fails to work, the system may not be able to provide the necessary power during an outage. The battery may not function properly once it reaches its shelf life.
An internally modular redundant configuration for a UPS system is an efficient way of protecting critical equipment of businesses. It can be easily configured to allow it to run close to its capacity. In this situation, a UPS system typically runs efficiently.
