Subject 3: Thunder Protection Feature
Introduction:
Thunder is such formidable natural force that it can render massive damage to electronic
products of all kinds. In thunderstorm season computer systems without powerful thunder
protection designs are vulnerable to electric surge damage. High-priced building with
thunder protection measures may be a good choice, but usually costly and with corners
uncovered. The best solution for both cybercafés owner and common users would be
Thunder Series motherboards.
Thunder Protection Technology from Thunder Series Motherboard
Thunder series motherboards are integrated with double thunder-protection walls, one from
network port and the other from LAN chip. When it thunders, the first thunder-protection wall
will analyze and recognize thunder surge in network cable and transfer it to ground wire area.
The second thunder-protection wall will protect against any residual electric current or
runaway electrons to ensure safety of network card and other components of the
motherboard.
Laboratory test statistics on IEC61000-4-5 (1.2-50us) standardized thunder electric surge
tests have verified that Thunder series motherboard can endure up to 9KV electric surge
and protect the system from possible thunder damage.
IEC61000-4-5 (1.2-50us) Standardized Thunder Electric Surge Laboratory Test
Medium rise time: T1=1.2us±30%, T2=50us±30%
Test1:
Current Partial Discharge tests on Thunder Series Motherboards with double
Thunder-protection Walls.
Test Result:
Each MB can endure up to 9KV voltage of electric surge. Some motherboards
will restart (mostly depends on LAN chip), but no damage occurs to motherboards or
components of the board. System works normally after a restart.
Test2
: Current Partial Discharge tests on Motherboards without Thunder-protection function
Test Result:
LAN chips are damaged when testing voltage reached to 5KV. System fails to
operate normally (in most cases systems can not access to network) after a restart.
Conclusion:
Thunder Series motherboard can guard motherboard from thunder electric
surge damage with effect and ensure system security from as high as 9KV volts of electric
surge.
