LayerZero Completes 150A-600A OPTS Fault Testing At KEMA-Powertest Labs

Chagrin Falls, Ohio (April 27, 2002) LayerZero Power Systems, Inc. is pleased to announce the successful completion of Closing and Withstand tests of its 150A-600A Optical Power Transfer Switch (OPTS) product line at KEMA-Powertest Labs in Chalfont, PA. As a result of the testing LayerZero OPTS withstand ratings are as follows:

STS Current Rating (Two-source and Three-source systems)	Withstand rating for 480V, Three-wire + Ground systems	Withstand Rating for 208V, Four-wire + Ground systems
150A	65kA	100kA
250A	65kA	100kA
400A	100kA	150kA
600A	100kA	150kA

Based on test results, LayerZero’s 150-600A product family meets the criteria of High Energy (Type III) Static Transfer Switches. Upon application of faults with the rated available fault current, the solid state switches (SCRs) neither ruptured nor shorted.

In practical terms this enhanced survivability of the power stage under fault conditions would allow a mission-critical site to instantly recover from a downstream catastrophic fault/failures without having to perform any immediate repair to the LayerZero OPTS.
