Head: New Technology for Voltage Sag / Dip Generators Reduces Size, Weight, Cost

Power Standards Lab of Emeryville, California announced that it will be awarded U.S. Patent 6,759,765 on July 6, 2004.

Alex McEachern, the President of Power Standards Lab, says the new technology combines the advantages of IGBT's,
electromechanical switches, and TRIAC's, to reduce the size, weight, and cost of voltage sag generators. Voltage
sag generators are used to create disturbances on electric power lines.  Engineers use these disturbances to 
verify that their industrial equipment designs will work throughout the world.

Following its tradition of supporting its existing customers, Power Standards Lab says that the new 
patented technology will be offered as an optional upgrade to its Industrial Power Corruptor line of voltage sag generators.  

PSL sag generators are used throughout the world for testing equipment that requires up to 600 amps peak.  With 
the new technology, this upper limit will be extended to 1500 amps peak without increasing the size or weight of 
the sag generator. 

The new technology will be especially important for testing compliance with the new International Electrotechnical
Commission standard, IEC 61000-4-34, that will likely be released in 2005.

Power Standards Lab is the world leader in voltage sag immunity testing, a process that makes
sensitive electronic systems more rugged, and more tolerant of the poor quality power found
throughout the world.
