9 Corporation Introduces 1st UL Approved Ground Line Surge Protection Device

9 Corporation introduces the world's first UL approved filtering device to safely install in series with the ground line of electronic equipment to completely eliminate ground transients.

(PRWEB) March 6, 2004--9 Corporation introduces the world's first UL approved filtering device to safely install in series with the ground line of electronic equipment to completely eliminate ground transients. Power quality is paramount in todays sophisticated electronic environment and surge suppression devices are becoming widely used to prevent system failure, lockups, false alarms, data corruption, and component degradation. But these devices only protect the live and neutral wires and do not address the problem of harmful transient energy entering a system through the ground line.

The GTT is the first suppression device approved by Underwriters Laboratories to go directly in series with the ground line of electronic equipment to prevent disruptions in operation because the technology incorporates a patented circuit with no moving parts or sensitive electronics, and as a result, does not pose any threat to intrinsic safety ground. No previous power protection technology addressed the unsolved problem of ground transients entering a system through the ground line," explains Dan Weaver, ECM Electronics, Ltd. By eliminating transients on the ground, potentially damaging voltages have no means to enter equipment."

For years engineers have tried to put inductors on the ground line to eliminate ground transients, but suitable-rated inductors had too high dcR and were unable to cover a wide enough frequency range to be effective. By combining newly-developed core properties in this filter, we have solved these issues. The GTT works by opposing changes in electron flow on the ground wire. This slows the damaging rise and fall time of a transient voltage wave form rather than clipping it off, controlling frequency rather than amplitude.

The Ground Transient Terminator (GTT) technology developed by ECM Electronics and distributed by 9 Corporation sets a new standard for power protection and provides end-users and manufacturers with a new dimension of product reliability.

The GTT is available today in the hard-wired block version and can be custom-designed to fit any application. The line cord version is currently in development and scheduled for production sometime this summer. Also under development is a lightning barrier device which integrates the GTT technology for use in cable television/satellite and security monitoring systems.
