can you pls. help me in defining the important uses (in laymans terms..tama ba spelling..?) of the following equipments:

1. auto voltage regulators

2. line conditioners

3. surge protectors

4. UPS - uninterupted power supply

5. line filters

6.

7.

you may also add other stuff that you use to protect your system.

many many thanks.

i use a power/surge protector with a built-in power saver. my device has a delay mechanism so that it waits the power to normalize before it sends them to the appliance -- so far m satisfied with its being a protector -- because it solved my problem -- before, my audio gears usually react whenever a switch is turned on.. now that THUD sound coming from my Audio was gone.

ako may dagdag

6. a piece of old/new basahan. pantakip laban sa alikabok. hehehe

in my case, a piece of kakaibang papel, parang oily ang dating na parang creep paper..

seriously,
avr din ako. protects against mataas/mababang bigay ng voltage sa outlet also from surges sa pag-on, like mentioned above and sa fluctuation, ok yung may delay. sa kin kapag ako mag-on, alisin ko delay after ko i-on. then kapag naka-on na avr, balik ko yung delay. using Yaden from one of the pdvd members, imported from Raon.

i use auto voltage regulators back then. but since voltage is stable from where i live i now, i just use belkin surge protector which includes lightning protection coming from tv antenna & phone line for my HT gears on top of the surge protector that is installed in my main electricity switchboard that protects the whole house for power surges. ups/line conditioners, tsaka na lang cguro pag may nakita akong mura sa ebay

do avr's offer surge protection? why is there a need for a delay mechanism? doesn't the avr already regulate voltage automatically? lastly, what are line conditioners? reason i ask is that these equipment aren't exactly cheap, especially if you require high wattage and 110 volts. perhaps some of our engineer colleagues can enlighten? thanks.

delay: i think for the surges that exceed the capability of the avr, madalas naman to kapag brown out then on ulit. o kaya sa pag-on mo pa lang.
tama ka: AVRs (as in receivers) already have voltage regulation, pero hahayaan mo bang sya ang first and last line of defense mo? mas mahal yun syempre. at sa palagay ko, you buy your avr(regulators) and other components relative to what you already have. diba like speakers relative to your amp or the other way around.
conditioners: eto yata yung nagaalis ng trancient voltages (di ko alam kung tama yung term) pero eto yung surges na iba na yung frequencies.

all of this, ay ayon lang sa aking perception at pagkakaintindi. to all, please clarify if anything is wrong/missing.

thanks

Hmm, I thought those receivers(AVRs) have voltage rectification, not regulation.

Here's a good site to learn more about protecting electronic stuff:

http://computer.howstuffworks.com/surge-protector.htm

There's an excellent section there that tells you how to identify a good surge protector when buying one. Also, it tells you that a good UPS (online) does surge protection and line conditioning at the same time.

berniebau · « **Reply #9 on:** Dec 22, 2004 at 03:28 PM »

pero hindi ba na nakakapagregulate sya up to some extent? pero tama ka sir rectification lang halos lahat naman ng equipment. uy ayos itong howstuffworks.. eto ang pass time ko parati dati kapag "standby support".. napalitan ng pinoydvd. hehe

My limited understanding is that the voltage being regulated inside a receiver is DC. Intended for preamps and digital processing circuits. What we want to regulate to protect an appliance is AC, or what goes before the receiver's power transformer.

Yup, howstuffworks is an excellent site.

berniebau · « **Reply #11 on:** Dec 23, 2004 at 10:41 AM »

tama ka dun sir.. kaya to rebelsage whether having an avr(regulator) is important or not? -> medyo gagastos na din ako just to be sure. meron naman nasa 1.5-2.5K lang.

which brings me to another issue.. what's the difference between the 1500va ng yaden worth 2k++ sa... say Stavol na worth twice with the same rating? uhmm...<kamot sa baba>

sa tatak lang kaya/quality/raw materials? pero sana hindi sa protection features nagkaiba.

rebelsage · « **Reply #12 on:** Dec 23, 2004 at 02:18 PM »

very informative site, av_phile. seems that you really need a good surge suppresor in addition to an auto volt regulator to protect against those surges. and based on the site, not just any surge suppressor will do; generic ones apparently are no better than mere extension cords. i'll likely check out pcx or villman this w/e. cheers.

bumblebee · « **Reply #13 on:** Dec 29, 2004 at 02:09 PM »

sirs,

what do i need, a surge protector or an avr? or both? if both, which one's connected to the outlet?

many thanks.

av_phile1 · « **Reply #14 on:** Dec 29, 2004 at 02:31 PM »

Personally, I'd connect in this sequence before any appliance:

1. Outlet - Surge Protector - AVR - UPS (offline) - line conditioner
2. Outlet - Surge Protector - UPS (online)
3. Outlet - Surge Protector - AVR

I've read that Surge Protectors should be connected (grounded) to the outlet for it to work. What happens if the outlet istelf itsn't grounded?

diver · « **Reply #18 on:** Sep 15, 2005 at 07:27 PM »

We use an OMNI 1000W AVR with power on delay and surge protector. According to the guy who sold us our tv, the best AVRs are those that have servo motors. Whatever that means

Good door locks/gate locks - protection from theft

Educate family members and/or household help about which wires go where and the proper operation of your gears - protection from the most common cause of failure...
"dad/kuya, natanggal yung wire nung nagwawalis si xxxx tapos kinabit ko. pag-on ko ayaw na...."

Disposable de-humidifier in the room where your gears are- helps protect from moisture induced failure

can you pls. help me in defining the important uses (in laymans terms..tama ba spelling..?) of the following equipments:

1. auto voltage regulators-as the name implies is to regulate the voltage flactuations,it will help you maintain your prescribed voltage output whithin the proper range.it also prevent electrical surges that causes your output to exceed more than 240volts but does not maintain the voltage output when the input current drops meaning it cannot sustain the 220v output when the input current drops below 220v.it also acts as a power on delay when the electricity suddenly turns off-on(to prevent sudden elctric surge that exceeds more than 240v).You must get proper wattage capacity to prevent overload ha.

2. line conditioners-filters electrical noises that causes statics on your gears.

3. surge protectors-prevents surges from electrical inputs meaning abrupt rise in current that goes higher than 220volts,same as auto voltage reg but with lesser features.

4. UPS - uninterupted power supply-serves as back up power supply in case there's a power failure or when power supply drops(as in battery packs).I think this is better than auto voltage regulators bec certain brands like APC have the all in one function like autovolt regulator,line conditioner/filter,surge suppresor/protector and back up power supply when thre's a power failure.One drawback is its PRICE.

5. line filters-same as line conditioners-surge protectors(i think)

6.

7.

you may also add other stuff that you use to protect your system.

many many thanks.

So for me id rather invest in a good UPS all in one product than get the individual ones,if only i have the money and sense to get one.

OT:
ung po bang ref nu kinakabitan nu ng avr/surge protector? kasi kadalasan napapasin ko, ung mga ref direct from outlet lang e.. hehe

again this site is very helpful:

pls recommend affordable and dependable (within 3k range) na avr/ups!

Delikado yan. If the AVR can't handle the power requirement of the ref (esp. the surge when the compressor kicks in), it can overheat / meltdown (if it doesn't blow the fuse first!) and can be a fire/electrical hazard. As a general rule, I think, any appliances with compressors (aircons, refs) can over-tax most home AVRs meant for TVs, stereos & PCs - unless you get an 'industrial strength' AVR.

This happened to us before - sinaksak nung katulong yung ref sa AVR (PC AVR, 500watts lang ata). I think what happened was the fuse didn't blow (either it sorta melted but didn't break the connection, or because of the 'cycles' of the compressor hindi siya over max current all the time) until the AVR itself overheated (the paint almost melted off). Buti na lang na-amoy namin yung AVR bago pa siya tuluyan lumiyab. But the AVR was totally trashed and unuseable even after it cooled down.

leomar · « **Reply #24 on:** Sep 19, 2005 at 06:40 PM »

may nabasa rin kasi ako mula sa ibang site na sinaksak ung aircon sa avr, patay, sira ung aircon! hehehe

pede po ba ung ganitong connection?

outlet ---> yaden avr ---> extension cord/srtip na marami switch ----> tv,dvd,avreceiver,pc

delikado ba ito?

kasi ang setup ko ngaun

outler ----> extension cord/srtip na marami switch ----> tv,dvd,avreceiver,pc
2 lang kasi outlet sa room ko kaya ganyan hehe

Wala namang sigurong problema yan as long as you don't exceed the maximum wattage (current) rating of your AVR. For example, my receiver can supposedly use up to 680 watts so I had to get a 1000watt AVR (which leaves me a little enough left over for the XBox, etc.)
