If Shunt Mode “All three modes” suppressors can cause data problems, what should I look for in a power line surge suppressor?2023-03-20T14:29:17-04:00

Experts recommend the Series Mode type for modern computing systems, or any sensitive electronic system that may be interconnected with other electronic systems. A heavy duty surge reactor acts to deflect surges rather than diverting surges where they can do further harm.

The following list of specifications should be carefully examined and compared:

  1. Let-through voltage at maximum rated surge (not simply clamping level, which is the onset of clamping) using standard test pulses. (Let-through voltage is the amount of the surge voltage that is let-through to your protected equipment and should be as low as possible. 180 volts is the theoretical lower limit for 120 volt power lines).
  2. Service life for various surge levels (including maximum rated surge). A service life of 200 minimum worst-case surges is recommended for a five year life in high exposure locations.
  3. Filter response. (i.e. greater than 30 dB at 100 kHz.) The important frequency range for surges is 5 kHz to 500 kHz. Greater than 20 dB at 100 kHz is desirable.
  4. Safety Ground Wire contamination should be avoided if equipment is to be interconnected. Suppressors that claim “all three modes of protection” divert surges to the Safety Ground Wire and should not be used with interconnected equipment.
  5. Self-test or failure indication (not “protection working” indicators which are often little more than power applied indicators).
Does surge induced damage occur all at once or over a period of time?2021-04-05T10:35:01-04:00

Both ways, depending on the circumstances… A violent electrical storm can induce enough surge energy into power lines to destroy your computer in an instant, if left improperly protected. Smaller, internally generated surges can, over time, “wear out” delicate circuits, causing intermittent problems, and slowing down the operation of a system. Series Mode surge suppression technology, as designed by ZERO SURGE Inc., employs a surge reactor that serves as a power line filter, much like the oil filter in your car. The surge reactor filters out damaging energy, just as your oil filter removes impurities that can destroy your engine over time. The result with a good oil filter or a good power line filter is longer, trouble-free operation.

Can I plug your product into a GFCI or AFCI outlet?2023-03-21T09:16:15-04:00

Yes.  Zero Surge’s technology is compatible with GFCI or AFCI outlets.  When using our products in an ungrounded environment, we recommend replacing the receptacle with a GFCI, labeling it as ungrounded.  This adds a level of safety protection should there be a short in the connected equipment.
