I came across these questions on a forum and would like to know what some of your opinions are. I am looking to purchase several surge protectors for the small school I work at. Wanting something for a decent price.
From what I have gathered there are several factors to look into for a surge protector.
1. Clamping voltage. Anything 350 volts and below is preferred. I have seen items with clamping voltages of 400-500 which can be too high for certain electronic devices.
2. Response time - < 1 nanosecond. Just the other day, I saw a surge protector with a response time of 1 second! Absolutely unacceptable! These spikes/surges and strikes of lighting happen almost instantly which means you need a device capable of near instantaneous action. It's really important otherwise those surges can damage your gear by the time your surge suppressor reacts.
3. Joule rating - I've read that a rating of 600 joules and above is what to look for.....and that's all I've found. What is 600 joules? How effective is 600 joules? A small spike? A long lasting surge?
