OVER-VOLTAGE PROTECTION

[unit_399]

Just recently, a HUGE lightning storm rolled through our area of Colombia. We had a direct lightning hit on our power lines, and lost power for several hours. I've installed over-voltage surge protection on everything on our farm, and fortunately we didn't lose anything to the power surge. Our neighbors weren't as fortunate, and lost their TVs, refrigerators, microwaves, and other electronics that weren't protected.

I always install a 130vac varistor on the line input of any electronics we buy because it's CHEAP INSURANCE !! I purchased 100 GE V130LA20A 130V 6.5KA Metal Oxide Varistors from a seller on Ebay, and it was one of the best buys I ever made. Just install one of the varistors across the AC line input to any device, and it will absorb any HV surges from lightning or whatever.

I've installed a varistor across the ac line input on all of my radio equipment, as well as across all of the wall plugs in our house and in my shop. Haven't lost a single piece of equipment since I did this. Persons that utilize cb or amatuer transceivers need to protect their equipment in the same manner. Having a tall antenna invites lightning, and protecting against it is a must !!!

The answer is to install a varistor across the ac line in ALL of your equipment. Just solder the varistor across the AC line where it enters the equipment, and then breathe easy. 73s.

MOV's are cheap insurance. If you don't mind my asking; how much did 100 of these set you back?

Thank you for confirming to all those naysayers that a simple MOV on the power leads can indeed make a big difference. Too many people think that there is NO protection against lightning. They are wrong. Nothing is 100% failsafe but there are indeed a lot of things that can be done cheaply that help a lot.

I will look into this further myself. Never can be too cautious with lightning or even a surge!! Thx for the info 399. Have a good day.

$99.00 + 5.00 shipping. I thought it was a great price.
