How important is "clean power" and a "surge protector"
I just bought a 61" Samsung DLP.
How important is getting a good surge protector (I'm guessing "very"). How important is getting "clean noise" -- Circuit City is recommending a $80 Monster Power which has "clean noise"... Thanks for any help, Bharat |

Perhaps they meant that it cleans up (or removes) the noise. The monster power unit is OK, but it isn't the best value. One of those battery backup UPS devices used for computers might be a better choice. You can get small ones for far less than the monster unit they are selling. I would still use an additional power filter on the output of the UPS since you are dealing with sound and video equipment. TripLite makes good power filters. -john- -- ================================================== ==================== John A.

John, The $80 Monster Unit is joint surge protector (1800 joules) and clean power. Does the TripLite offer both? Thanks for any help, Bharat |

Lets look at the quality of that Monster Cable product.
Take a $3 (retail) power strip. Add some $0.10 components. Sell it as a Monster Cable product for how much? You too would love to have this price markup. Why would a salesman in Circuit City, with no basic electrical knowledge, recommend that Monster Cable product? What is his motive? All appliances contain protection that can be effective at the appliance. If that plug-in protector was so effective, then those parts are already inside the appliance. Internal appliance protection that is effective if not overwhelmed by the typically destructive transient. Every incoming utility must connect to the same protection. What is that protection - a protector? Of course not. Junk science reasoning using word association says "surge protector = surge protection". That internal appliance protection, instead, assumes the single point earth ground (the protection) connects 'less than 10 feet' to every incoming utility. Some utility wires connect directly to protection without a protector - ie. cable and satellite dish. Others require a 'whole house' protector to make that 'less than 10 foot' connection. Once we eliminate the hype (from those educated by Circuit City salesmen), then we can move on to what professionals say. For example, this figure from the NIST demonstrates why even multiple earth grounds can compromise the protection 'system': http://www.epri-peac.com/tutorials/sol01tut.html How to identify ineffective protectors: 1) Protector has no dedicate connection to the all so critical single point earth ground, AND 2) manufacturer avoids all discussion about earthing. Notice the Monster Cable product violates both. 'Whole house' protectors are so effective that the telco installs one, for free, on your incoming phone line. Cable company, if employees were properly trained, dropped their cable down to the single point ground before rising back up to enter building. But the most common source of destructive transients is AC electric - which is also wires highest on the utility poles and that connect directly to every appliance. We still build new homes as if the transistor did not exist. Therefore YOU must verify the integrity of single point ground (ie. meet or exceed post 1990 National Electrical Code requirements) and must install the 'whole house' protector on AC electric. Some minimally sufficient 'whole house' protectors are sold in Home Depot as Intermatic IG1240RC and in Lowes under the Cutler Hammer and GE brand names. Yes, all electronics require building wide protection that costs about $1 per protected appliance. So how much is that Monster Cable product being pushed by a salesman? Salesman who must avoid mentioning earth ground to sell a product that may cost 80 times more money per protected appliance. "R. Bharat Rao" wrote: I just bought a 61" Samsung DLP.

Personally I would buy a reasonably priced name-brand power thing and
avoid the Monster pricetag, as posters have mentioned. Monster brand has this 'feel' to me that is reminiscent of Bose - ok product, lots of hype, lots of markup. Monster does NOT make the best speaker cables, for example, no matter what they say - there's brands out there that cost 10x Monster and deliver more thruput. But who cares on a bigscreen tv. If you wanted to go all out I'd recommend what a friend once advised me to do with my computer - plug a powerstrip into the wall, a power conditioner (UPS into) that, then another power strip into the UPS, then the TV into that. Battery backup of course is kind of goofy for a TV, who cares. |

Read their (manufacturer) specs with more care. That is if
you can even find numeric specs. Plug-in UPS manufacturers make those specs difficult if not impossible to obtain. And what would those numbers demonstrate? The plug-in UPS does not even claim to provide effective protection. Since they denied consumers of those specs, then urban myths often promote that plug-in UPS for hardware protection. Furthermore, the plug-in UPS can output transients when in battery backup mode. This UPS works just as its specs claim. When unloaded in battery backup mode, the 120 VAC power is two 200 volt square waves with a 270 volt spike between those square waves. You tell me. What kind of protection does that UPS really claim to provide? Again, how to identify ineffective protector - such as that plug-in UPS or power conditioner. 1) Has no dedicated connector for a less than 10 foot connection to earth ground AND 2) manufacturer avoids all discussion about earthing. wrote: Personally I would buy a reasonably priced name-brand power thing and avoid the Monster pricetag, as posters have mentioned.

I do -- I want something effective, simple, quick -- and if possible not too expensive -- the UPS's I've seen don't quite have 400W (the TV alone is 200W) without getting a lot more than the Monster Power strip.... Could you recommend a reasonable surge protector that is as effective as the MOnster brand ($50 if I wanted only a surge protector) and not as expensive... I reaalize the "clean power" thing is a red herring (and located the source of the interference -- my new Blackberry, lying next to the speaker:-) Thanks Bharat |

wrote: Tom, sorry... so how do I get "whole house surge protection" Contact a competent local electrician and explain what you want. Make sure that all incoming wires (power, telephone, cable) etc. are grounded at a single point at the house entrance point and appropriate surge protectors applied to them _at_this_point and that external metallic structures, such as antenna masts and metallic dishes are also grounded to this point. A single plug-in surge protector in the TV mains plug is nearly useless, if the TV is connected to a computer (e.g. for playing games) and the computer is connected with a modem/ADSL to the phone line. A surge from a badly protected phone line can flash over the modem/ADSL, go through the computer and do some damage there, then move on to the TV, do some damage there and then end up into the plug-in surge arrester and finally into ground. The surge arrester worked, but everything else had been damaged before that :-). So it is really important that all the possible paths are protected and it is much easier to do this at the point where all these wires enter the house. But you really need a competent electrician to do this, do not attempt to do it yourself. Paul |

All consumer electronics equipment from the large manufactures meet the ISO
standards for power supply design. These sets all have adequate protection. The type of surge protector that you have in an AC bar at the cost you are looking at may not even be as good as the one built in to the power supply of your equipment. The proper solution is to have a UPS that is rated to a more than double that of the load that is is to be used on it. A good qauality UPS will switch over to the battery inverter during power brownouts, which are the types of disturbances that cause the most damage to equipment. As for surges, a good UPS will have a very good design to also protect its own systems. As for these AC bars with surge protection, it is impossible for the price that they are asking, to have a very good protection. If there is a lightning strike near to you, most any system you can afford will never be able to block the surge. Add the $80 to a discent UPS, and you will be much better off to protect your equipment. -- Jerry G. ====== "R. Bharat Rao" wrote in message news:VfvUd.66322$8a6.43276@trndny09...

Tom, sorry... so how do I get "whole house surge protection" You can also call your power company. They will install a unit that goes between the electrical meter and the meter socket/frame. I recall mine being about $115, and it was installed for free when they did the off-peak meter, plus they billed it to my electrical bill (so I didn't have to pay that day). -john- -- ================================================== ==================== John A.

Some minimally sufficient 'whole house' protectors are sold in Home Depot as Intermatic IG1240RC and in Lowes under the Cutler Hammer and GE brand names. Responsible suppliers of electrical equipment also sell the minimally sufficient protectors. Products from hyped manufacturers as APC, Tripplite, Belkin, and Panamax don't appear anywhere on a list of minimally sufficient. Additional examples (a short list) of 'whole house' protectors include other serious manufacturers such as Square D and Leviton: http://www.smarthome.com/4870.HTML http://www.smarthome.com/4860.html http://www.ch.cutler-hammer.com/surg...ucts/chsp.html http://www.leviton.com/sections/prod...d/npleadin.htm http://makeashorterlink.com/?Z1B7539A1 (Square D) http://www.dale-electric.com/ditek.htm http://www.deltala.com/prod01.htm http://www.deltala.com/prod02.htm http://www.ditekcorp.com/dispInfo.cfm?ID=280 http://www.ditekcorp.com/dispinfo.cfm?id=579 http://www.ditekcorp.com/dispfamily.cfm?id=3 http://www.keison.co.uk/furse/furse06.htm http://www.lightningrodparts.com/surge.html Then there is a benchmark in protectors - www.Polyphaser.com .. Just another name unknown to those who recommend useless plug-in protectors. But the best value is found in Lowes and Home Depot. And lets not forget, the protector is the equivalent of wire in a protection 'system'. The protection is earth ground. That single point earthing must have, by far, your most attention. Everything else in a protection 'system' is but a peripheral to that #1 most critical component - earthing. "R.

It is important to have a good air purifier also. LCD and DLP projectors
have air filters installed but they will not filter tobacco smoke and other polluntants such as from wood burning stoves and gas fireplaces etc, which will ruin the LCD and DLP projector optics! I have seen it too many times as a TV repair tech. Dave On Mon, 28 Feb 2005 02:22:45 GMT, R. Bharat Rao wrote: I just bought a 61" Samsung DLP.
