Load shedding – the best way to manage your UPS downtime

Load shedding – the best way to manage your UPS downtime
05/10/2017

Load shedding is the process whereby, a process where the load on a UPS is reduced by sequentially powering down specific hardware when the UPS is running on battery power.

This deliberate shutdown on electric power in parts, will prevent a failure of the entire system when the demand tensions the capability of the UPS system. This reduces the load on the UPS system and increases the runtime for the remaining loads.

The diagram displays how the network should be prioritised into A,B and C order in which ‘A’ type loads must be kept running for the longest time and ‘C’ type loads the shortest time.

Priority shutdown

The priority shutdown can be achieved in three ways:     Programme output sockets available on some UPS systems

  Intelligent power distribution units

  UPS system monitoring and control shutdown software – with each server configured to run for different time periods before shut down.

Load shedding is most common practise of managing potential UPS downtime where there are multiple servers or server clusters to protect.
