Cyberex Offering Three Types of Switches in DSTS Line

Cyberex LLC (Highland Heights, OH) announced that the company now offers three different types of switches in its Digital Static Transfer Switch (DSTS) product line. Type 1 DSTSs feature smaller, undersized SCRs protected by a fuse. The Type II switches feature SCRs that short-circuit in the event of a fault, but not a rupture; no fuses are required with this type. The third, Type III, are sized so they can withstand a fault. Cyberex claims that this type neither shorts nor ruptures and requires no maintenance.

The DSTS is suitable for the needs of a data center. It selects between two or more independent ac power sources to provide the best available power to the downstream electrical load. Cyberex claims that in an emergency, the DSTS transfers to a good source from a failing source in less than a quarter of an electrical cycle, or four milliseconds. The DSTSs feature front and rear or front and side access, convection cooling and redundant internal power distribution to all system control boards. In addition, these units feature fast source reacquisition, dual- or triple-redundancy of key system components and 20A to 4,000A two- and three-source systems.
