UPS in Parallel Connection

This was originally posted on APC forums on 3/30/2009


Hi Guys

Is it true that if you connect two UPS in parallel the capacity of the two unit will sum up? like for example, 60KVA, if their is two 60KVA and connected in parallel can i expect that i can get 120KVA for max. loading?

Also the Symmetra PX 60KVA able to support parallel configuration.?

Thanks

You might be able to get away with using them in parallel if you have, for example, a server with two redundant power supplies. Plug the two PSU's into the two units, although management could be a bit tough, and if one of the PSU's fail, you will only be drawing on one battery.

ok thanks for the info.

So in that case if the symmetra is not capable of parallel connection, there's any other way or what UPS from APC can support parallel connection...

Thanks

This is generally true of UPS' with parallel capability. In short, you can either parallel for capacity addition or redundancy.

The Symmetra PX 60KVA does not support parallel configuration for "capacity addition".
