Has anyone any ideas for a low-cost telecom protection which can pass
regulatory tests such as FCC Part 68 and ITU K.20/K.21? I'm currently using
a combination overcurrent fuse and an overvoltage protector (thyristor type
Bourns TIPS). These are pretty expensive, though, and I'm looking for some
ideas to lower costs.
Now, I've seen some designs which only have a varistor (MOV) inside, but I
doubt that such a design would pass regulatory tests. And replacing the
overvoltage protector with a gas-discharge device probably won't be much
cheaper either.
Anyone have any experience with this? Thanks in advance!!
