Have you ever felt overwhelmed by the wide variety of brands or even models you can choose from when shopping in malls?
It’s even worse if you buy your stuff online, whether it’s products, gadgets, jewelry, etc., that you can’t find online.
Buying gauze filters is no different, not only do we have to sneak through hundreds and thousands of different brands and models, but we also have to fight against terms like Joel’s rating?
Do you get them with low or high notes in joules?
I can feel your pain. The same thing happened to me when I ordered my first surge protector, I ordered it blindly and I made a mistake.
Fortunately, I was able to bring it back for another model that suited me.
I hope you don’t make the same mistake I did, and I hope the information below will help you.
What is the nominal value in joules of the overvoltage protections?
If you’ve never had a network security device, it’s highly unlikely you know what joules are. Joley is essentially a single measure of energy (watt-seconds).
For example, 400 joules is like leaving a 400-watt vacuum cleaner for a second.
The joule rating is commonly known as the Energy Absorption Rating, which essentially indicates how much energy (power) a surge protector can absorb before it stops working (and also protects your equipment from voltage surges).
The number of joules in the detainee is reduced when a spike due to lightning or transients is needed.
Do you need surge protectors with a high joule value?
The answer is NO.
A lightning protector with a high joule value in your home or office is definitely NOT , which is an indicator for the best protection against lightning strikes.
Instead, select a device with a forward voltage of and a response time of .
The forward voltage of, also known as overvoltage protection The rated voltage or terminal voltage is the maximum voltage that the overvoltage protection device may carry before starting the overvoltage protection device, and allows only the standard current to pass through the connected loads (your computer or electronic equipment).
Response time is the time taken to activate an overvoltage protector – usually measured in nanoseconds.
Longer reaction times increase the risk of damage to connected devices during voltage spikes. Try to get a lightning protector with a reaction time of 1 nanosecond or less than.
A lightning rod with a high Joule value in your home or office will not provide better protection against transient phenomena such as lightning strikes because it is not a measure of the performance of a lightning rod in minimizing peak voltage.
While there are other factors to take into account when choosing the most suitable protector for your home, it is important that the next time you buy an protector, at least check the response time of joules at, joules at and the flow rate of / connection voltage of .
If you have high-end equipment at home or in the office, I strongly recommend that you purchase a surge protector with a nominal value of Joule and Joule, with a fast response time and a blocking voltage of no more than 400 Volts.
