High voltage Protection?
581930
I don't know about any high voltage protection for this hot shoe, but have not had any problems with the shoe. This shoe does work well for me on my digital SLR. Due to my DSLR not having a plug in for my flash unit, I place the hot shoe on top of my camera's hot shoe in order to plug in my flash unit that's placed at a remote location (on a flash bracket).

I do not Know - It did not work as a Hot Show - Do not recommend it for anything.

This unit is better than nothing against "power surges" To be fully protected. a "UPS" box might be suggested.

There are better one's on the market protection wise, but this one filled my need to fit in a tiny space. I would say it is better than not having any surge protection. I got zapped by a lighting strike last year and that took out the circuit board in the garage door opener. So any protection is better than none. It has a 3 pronged plug and 2 led lights to let you know it is working.

The unit provides protection against electrical spikes and surges. Your problem is with the electrical utility provider could be a transformer issue

Although I haven't used mine yet, I can only assume the higher voltage breaker is there to prevent any overload from tripping a 30amp breaker.

I don't think so but you should ask the manufacturer if they have a higher voltage version

I've used this device as well as others. Shielded cabling helps because it can limit transient surge voltage from getting to internal conductors. However these devices protect the internal pairs of wiring, provided the surge came up the cable and through the conductors. Shorting the surge to ground and away from sensitive equipment. Key is to have some cable length post surge protector to device, to allow for some current dissapation, before reaching sensitive equipment. I usually accomplish this with a 7' to 10' patch cord.

Also wanted to note that this is for incoming power problems only. You should also use surge protection at each electronic component, like an outlet or strip with surge protection. Internal surges can happen beyond your power source, example: Frig on same circuit, as a vacuum is turned on, can cause an internal surge on this circuit or one near it. This is a better setup for having all round protection. Most people I know have one or the other, better to have both.

What you seek is called a "Voltage Stabilizer (or Regulator)." This is a far more expensive device as it requires the use of batteries to give electricity when it dips, or store electricity when it exceeds. This unit does surge suppression, EMI rejection, and the will MONITOR incoming voltage and will "Boost" input voltage if it dips to an unsafe level, and will "Trim" the input voltage if it gets too high.

The surge protector is on in case of a power surge to protect your electrical appliances from shorting out

No surge protection. It barely weighs anything. Not sure about the shielding. It's basically just a cheap power strip. If that's all you want then you will be satisfied.

it is a surge protector - and will protect you from a bad 'spike'. but for sensitive equipment that requires line conditioning, you might want to get something more advanced. this is a heavy duty outlet strip with a circuit breaker.

looks after RF hum, but not really a surge protector. try one of the fur man products for that application. or trip lite works well too.

i don't think it is a surge protector. it does act like a circuit breaker and shuts off when it gets too hot. you'd really need to ask the manufacturer about surge protection.

absolutely. The breakers prevent from overloading the circuit ONLY. This device protects against surges, high voltage, low voltage, open neutrals or grounds, etc. Small price to pay to save several thousands worth of electrical devices

it would have to be below 100ma or it would be lethal. I just ordered mine, but have no way to measure amperage on that high voltage.

David, I will need to disagree with Chris on the surge protection issue. By my experience, I would say that a surge can cause damage to hardware up the CAT5/CAT6 line from the NETGEAR Powerline (The XAVB2501 to be exact). All of my equipment was surge protected except the XAVB2501 as it was recommended not to use surge protection on these. After a large storm one of my Powerlines was non-operational and the Cisco switch I had the Powerline linked with was also toast. The switch had been powered though a surge protector that had many other devices attached to it. All the other devices on that protector were fine. Could there be another cause for my switching being toasted that night? Perhaps, but being a resident of a rather stormy area of the united states I've always kept my electronics surged protected and I've never had anything release its magic smoke until this. The odds seem unlikely that the switch could be fried by anything other than the one device that was not surge protected, the Powerline XAVB2501. My thoughts, Noah P.
