Units measured 1U x 250mm deep

XTS (Cross Over Transfer Switches)

Ideal for managing high in-rush current when starting systems

An XTS runs off two supplies and automatically switches the outlets to the remaining live supply if one supply fails.

Normally Supply A provides power to the bank of Outlet sockets A and Supply B provides power to the bank of Outlet sockets B. If Supply A or Supply B fails, then the unit automatically transfers the remaining live power supply source to both banks of Outlet sockets A & B.

Standard specification

Dual 4 in-line Outlet connector banks (A & B) to IEC320 (10A or 16A)

STS (Static Transfer Switches)

An STS runs off one supply and automatically switches to another supply when the first supply fails.

Normally Supply A provides power to all the Outlet sockets. If Supply A fails then Supply B provides the power to all the Outlet sockets.

Standard specification

8 in-line Outlet connectors to IEC320 (10A or 16A)

Transfer Characteristics and Equipment Safety

Be aware that having 2 phases in a rack/cabinet gives the possibility of 400V AC across phases and equipment should be chosen with regard to this. Only qualified personnel should specify and connect this type of equipment. STS & XTS switches will switch most rapidly (approx. 7mS) when connected to the two most adjacent phases (e.g. 1 & 2 or 2 & 3), otherwise the switching time will range between 1/4 & 3/4 of an AC cycle (i.e. 5 to 15mS)
