Sine Control Technology Inc. is the new name for Sine Control International Corporation. Since 1980, we have been the industry leader in ultra high performance Transient Voltage Surge Suppressors. Our TVSS products, now called PowerClamp", are the very best TVSS units in the industry. They offer clients worldwide uncompromised performance and protection against power line disturbances that cause unreliability and failure in sophisticated electronic systems. Sine Control has an extensive private sector customer base as well as U.S. & foreign government users where equipment failure is unacceptable. One example is the U.S.NavalWarfareCenter, who has issued SCT several Sole Source Justifications for Nuclear EMP and lightning protection. Sole Source Justification means that this client will use only Sine Control TVSS units, and no substitutions are permitted.
