Specs say that the clamping/let-through voltage is &lt; 85. I thought a quality surge protector's clamping voltage was usually 330V? Won't a clamping voltage of 85 make this thing unnecessarily eat itself quickly or at least quicker?

I believe that rating only applies to the data lines. if you look at the spec page on apc you will find this rating comes directly after data line protection and data lines protected.

This is a 110 volt power strip. It's for use in the US and cannot be used for 220/240 volt applications. This is a power strip, not a surge protector.

It doesn't say. Only says: UL Clamping Voltage (3-Line):UL1449 5000V. Also says: Continuous Duty Electrical Rating 15A/120V/1800W. Maximum Energy Dissipation 1080 Joules. Maximum Spike Current 72,000A. Hope this helps.

I have not used this device yet. I bought it to protect electronics while using my generator. Tripp Lite says it provides good surge protection. Output voltage is 120 +/_10% @ 89 to 147 v input.

Well, I guess the question was - IF a surge appears on line and burns up the protective circuitry, will this item still continue to provide power to equipment connector to it? The problem with it doing so is that the equipment hooked to it now unprotected. I'm looking for an answer myself, so more info from owners is welcome..

Hi. It would seem it must be rated for high voltage as when i passed 12v through it at 156 amps it tripped out after a 'couple of seconds' (which in itself is cause for concern!)

Hello Rob; I have used it on my Tv but not my computer. No particular reason. I would use a good powerstrip with a breaker but it would be best to check with a person who has the credentials before I used it on my computer. Somebody at Best Buy for example that is a member of their Geek Squad. Personally, if it were me ,I would do it because I have a 60.00 Powerstrip.

I think it's what APC calls the "let through voltage". See both:http://www.webopedia.com/TERM/C/clamping_voltage.htmlhttp://www.apc.com/resource/include/techspec_index.cfm?base_sku=P8VT3

In case people ever come back to read this, you should NEVER connect a surge protector into any surge protected UPS. This is because it causes a ground loop in the wiring, in which the smaller surge protector is constantly triggered into thinking there is a power outage, ever though there isn't one. What this does is causes power spiking across the entire power strip, which can damage the UPS, your connected devices, and errors across your devices due to lower than optimal power ratings. Buy non-surge protected power strips if you need more ports for your UPS.

The output of this (electronic) transformer is 11.7VAC (AC!), not DC. That being said, most low voltage DC switches will function OK with when used with low voltage AC. "jimyastic" makes a good point about circuit protection, however I would assume if this device conforms to required UL standards (UL approved?) then it's behaviour during use and when it fails has been satisfactorily addressed and shouldn't be of concern.

Noooo! You have this wrong - it is an extension lead for US power - the protector is a standard RCD which kicks in if there's a short somewhere! It DOES NOT convert from one voltage to another!! A voltage transformer always has to be in there! You plug a 110v item into this then into the 240v mains in the UK then you will have the protector trip which is preferable to having the US electrical item blow up on you.If you are unsure - please buy from a shop where you can speak to someone for advice, rather than buy off the interwebs and risk danger or wasting money.

You CAN plug it into a basic extension cord, its how I have one of them ran actually. It CANNOT be a plugged into a surge protector or power strip. Most likely because of the extra components and electrical circuitry interfering with their signaling.

The manufacture of any legitimate surge protector will design and test their device for surge clamping capacity and will generally express this in Joules. Generally the higher the number the better the protection but it gets complicated after that. The point here is that the manufacturer had not done that for this model and that might mean they have not tested it or don't want to tell us. The newer model 36036 is sold by Amazon and does include Joule rating and it is quite good for this price range and design.

This surge protector is warranted for life. The Underwriters Laboratories rating of this surge protector shows Maximum Energy Dissipation: 4320 Joules H-N: 3600 Joules H-G: 360 Joules N-G: 360 Joules Maximum Spike Current: 252,000A H-N: 196,000A H-G: 28,000A N-G: 28,000A UL Clamping Voltage (3-Line): UL 1449 400V Response Time: &lt;1 nanosecond (&lt; 1 billionth of a second) EMI/RMI Noise Filtration: 150kHz-100MHz up to 50 dB Reduction UL Listed to US and Canadian Safety Standards: UL 1449, UL 1363 The EFI/RMI components evaluated to the applicable requirements with UL 1283 NOTE: All UL information taken from retail product package. Warranty document references transient volltage device protection. I hope this information is what you need to make a purchase decision.

The voltage and current rating look right (9volts at 200milliamps), but O can't tell you if the polarity of the plug is correct for that device. There should be a little symbol near the socket that looks like a dot with a semicircle surrounding it and with a "+" connected to the dot in the middle (center positive). If that matches, then you're golden. If not, then you need to keep looking. Please note, the part of this adapter with the two spade-pins that plugs into the wall socket can separate from the body of the adapter and is notorious for breaking away from it. The only fix I've found for that is to glue it in place with super glue or model glue.

On the "Technology Research Website" they give some specs but the not the most important "clamping voltage" which I found through reading various sites. The joules rating is 510 but a low joules rating is not necessarily an indicator of an inferior product as wikipedia's reasonably good article discusses. Response time is usually very good for MOV types as I think this is since MOV is the least expensive design (wikipedia again:) Thats what I've learned so far. This product also looks more promising than the similarly priced & rated product that doesn't claim protection but only says "Surge Status Indicator" So I haven't decided to buy yet myself but hope the info helps others who are interested. P.S. I just called tech support at 800 780-4324 and was told the clamping voltage on this model is 700 volts. I have read that 400 or less is best on some sites about surge protection. The manuals for their other models show a lower clamping voltage and may be better.

No. I believe 220 has a different plug entirely (like an electric dryer) & I believe all Panamax surge protectors have a range of cutoff (like above 130, below 110). I have another one of their units connected to TV, stereo, etc which gives a voltage reading and it stays a pretty constant 117-119. A couple times I caught it dip (brown out) and it dropped to around 110, then shut off TV. Go to Panamax.com and look through their products, check the videos too. I actually had my computer plugged in to the sample that caught fire (Belkin), bought the Panamax next day. They're good products, I've been happy and feel safer with them. But no 220. Maybe on website they have something. Hope this helps.
