That would have been ideal, however the PTC solidstate fuses do not blow fast enough. And doing a solid state current sensor runs up the cost and has it's own set of problems. If you are supplying the current it is no problem as you have an easy way to sense and interrupt the current. But when you are dropping in-line to an existing circuit you have to be totally isolated, balanced, not affect the ethernet signal and able to cope with a wide variety of currents and voltages.

I'm sure you already thought about this, but is it possible to make a
device that recovers automatically after the short circuit has ended
while also responding fast enough to protect the port?

Is it a case where it's possible but costs too much?

We have been shipping for months.
The cost of having a Netonix port repaired is more than the cost of the fuse. And then there is the labor and downtime and other intangible expenses involved in blowing a port.

The prices are lower if you buy from one of my distributors. I don't encourage anyone to buy off my ecommerce site and pay full list price. That site is only there to generate sales for distributors.

All of my products have prices based on cost plus margin. Same formula across the board pretty much. I try to have unique products you can't get other places. If volume increases on a product, I sometimes adjust the price down due to the fact that my costs come down. For example, if I am buying 1000 surge protector PCBs, I may be paying $1 for each. But if I am only buying 100 of them it may be $2.50.

I recently adjusted the cost down on my 8 circuit tower surge protector for exactly this reason. Volume picked up, I worked on sourcing and buying and was able to drop the list price considerably and still maintain my margins.

Hi Chuck,

Great to hear about the new product, the POE Fuse.

Question & critique.
 When are these going to be available ?
 We would like to see these priced a bit more aggressive...
(At the current pricing, the cost of fusing multiple ports appears to be exceeding the cost of 'poe switch' it is protecting ! )

Regards.
