Surge Supression

Re: Surge Supression

the usual problem is when there is power cut. the power comes back on strong. this can damage items with bullshit power supplies like dvd players for instance. i have seen this a few times so surge suppression is important.

Re: Surge Supression

In designing Surge Protected circuits, like Engine Control Computers, at CAT, in the lab we found that MOV's are just too slow for suppression of sharp spikes. The device we wound up using was a solid state device from Motorola, called the "Transorb".

They are lightning fast and can absorb a huge amount of energy in non-repetitive pulses.

I would never use MOV's in a surge protector to protect my own computer.

I once had a Korean dial-up modem with a MOV, gas tube, and something like a Transorber across the phone lines.

Re: Surge Supression

They usually have a "Fuse" that blows out, during a powerful surge or HV spike.

I've sold literally hundreds of modems and surge suppressors for phone lines, to replace units with those fuses blown. (usually a Pico Fuse that you won't find at your local hardware store)

It's a good source of income for Computer Tech's. rofl
Especially, here in the lightning capital of the Western Hemisphere.
