What is a centralised power protection plan?

In a centralised uninterruptible power supply installation, a single UPS system is used to power all the critical loads. The loads connect to an electrical circuit via sockets or PDUs connected to sub-distribution board and LV panels which are supplied with uninterruptible power. In a decentralised power protection plan, a number of individual uninterruptible power supplies are distributed into the server room or datacentre environment to power specific loads or areas. The UPS may be installed within a server rack or at the end of a server row.
