7.7Multi UPS shutdown sequence (example with Static Transfer Switch)

Typical example of the backup time provided by 2 UPSs in redundancy through Static Transfer Switch.

ωThe Output load level of the first UPS is less than 50 %.

ωThe Output load level of the second UPS is 0 %.

1

As soon as they detect the loss of AC power, the Mgt. Cards notify the Network

Shutdown Modules that the system is running on battery power.

 

 

2

The Network Shutdown Modules continuously compute the “minimum number of

necessary UPSs”.

 

In this case we suppose that the minimal number is 1.

 

When the first UPS stops its output, the Static Transfer Switch balances the load on the

 

second UPS. Then we are in a typical « single UPS sequence »

3

ω The Mgt. Card launches the shutdown procedure for UPS 2.

ω As a result, each Network Shutdown Module proceeds with the shutdown of its

 

 

system.

 

 

4

Once all the computers have been shut down, the UPS shuts off (interrupts the supply of

power to the loads) to protect the battery.

 

Note: This function is not authorized on some UPSs.

5

Once the utility is restored, the UPS restarts all computers (if the shutting off the UPS

output function available).

The diagrams below present the sequence.
