Static Switcher Unit

[ruggedscot]

Have a static switcher installed feeding a server, now we have fed this unit from two seperate supplies, it is rated for single phase work and my query is this....

If for some reason we lose sync on the UPS units feeding the supply then we could have a difference of about 410v between like for like phases on the dual strings. Would this have an impact on the unit and would it lead to problems with the set up ?

The unit is an APC type static switch.

finally got an email back from APC about this one and thought that you might like to know the result in case you have any problems like I had.

A static switcher operates as two seperate units and as such any voltage between the two inputs doesnt matter, so yeas we can have a phase difference of about 415v on a 240v circuit and it wouldnt stress the unit.

That is 415v between input 1 and input 2, not 415v between input 1 or 2 and neutral....
