Is an AVR really necessary for our beloved LCD tvs? I justbought a regzarv700 and was suppose to get an AVR and was surprised how much these things cost. A 1000watts AVR cost around 3k. What are your thoughts? If its necessary ,How many watts for a 32" lcd tv? Saw one from cdr king for only 600 pesos. Will this suffice? I would appreciqte some comments from the experts. Tia

Bro, it all depends in your area. If there are no severe voltage fluctuations then you may not need an AVR. Me, here in Makati, don't use any for so many years now. As for the CDR King AVRs, these may suffice to your needs in case you decide to use one ( based on their specs, although some CDR King products are rubbish ).

Hope this helps....................

I think a 32 inch LCD only consumes around 120 watts so a 500 watt AVR will do. I wouldn't get a CDR-King though, get something from ACE Hardware or True Value.

For a 32" LCD TV, I prefer to use an APC ES 500VA UPS instead. This should be enough for voltage fluctuations/spikes, lightning surge protection and sudden power outages. And it costs less than php2.5k.

I had our NMT and (low power) HTIB connected to it as well. Or the HTIB can be removed from the UPS also.

TonyT has said this several times already but as he posted on the other threads, LCDs have smps power supplies that are autovolt types (100V-240V), therefore, less prone to damage due to fluctuations.

But he also said, if you can pay PhpXX,XXX.XX for an LCD TV then surely an AVR wouldn't hurt.

Me, I'd rather incorporate a delayed turn on in case of an On-Off-On-Off occurrences which happens during stormy season.

It's an added protection so go for it.

I'm also using same UPS as Ppoooh is using. HTIB and PS3 also connected to that UPS.

thanks to all your replies. Sir pooh. Where did you get the APC ES 500VA UPS? And how much?

^Any place that sells computer and parts should carry it.

Gilmore area for one.

Lowest price is at PC Options in Gilmore. Already canvassed this before. If I remember it right, around php200.00 lower than the next lowest price anywhere. Up to you to evaluate which would be cheaper for you (add transpo charges). Unless you really pass by that area.

Again, this should be covered by the said APC UPS. That is why I highly recommended the said APC UPS instead.

Additional advantage: You would also have the safety of flashing your NMT for firmware update purposes, if you do own one. Or if your LCDTV should need firmware update also.

My less than 2 year old Samsung HDTV died because of dirty power. So an AVR or even a UPS would be great to have.

get the servo type from cdrking. 1k+ lang

i do. sayang investment naman kasi if masira, i'm also plugging it on the 110v outlet, according to my friend mas ok daw ganun. so far never had a problem naman.

Yes, and still working fine. My relative is on commercial (factory) power line. With welding machines, etc.

1 year warranty naman sa APC yan.

i have an extra avr at home. the cheap one. the freebie that you get when you buy a pc. can i cascade it to my 1kVA servo type avr? or will it do more harm than good?
reason: sayang. walang gumagamit. baka it can offer additional protection. 2 voltage conditioners instead of one.
fear: the cheap avr will be the one producing the "dirty" power

The transformer inside might be too small, and may actually worsen the condition. Dagdag points of failure pa. Most cheap AVRs are relay-type din, madalas hindi malinis yung output nila while switching, and less precise din.

Imho, if one's gonna use an AVR, it better be a decent one. Kasi pag nagfail yung AVR, pwede idamay yung nakakabit na gamit. Kumbaga, pag gagamit ng supplements eh piliin ang mga low risk (mamaya malason ka pa, rather than makaiwas sa sakit).

bass_nut · « **Reply #20 on:** Jan 01, 2011 at 03:33 PM »

i agree with sir Ivan.. usually kasi mahinang klase lang yung freebies na avr na kasama ng mga pc.

to add.. please regularly check voltage output of your avr.. if you have APC UPS, this/these will usually emit tone (warning signal) when voltage is beyond the safe range.. yung kasing mga old svc-AVRs baka tumaas ang voltage output at maka-damage instead na maka-protect.. kung walang over-voltage protect, perhaps, aftermarket over-voltage circuit added on avr may help avoid the pesky over-voltage. minimal cost lang naman iyon.

my 2 cents view only

meron akong 2 lcd tv, mag 18mos. na running without avr...using a digitalmultitester, terminal voltage ko sa outlet nasa 230V AC..ok ang supply ng distribution company sa lugar namin, walang voltage flactuations...

sa mga lugar siguro na nagflactuate ang voltage..AVR is a must...

hapi new year!!!..mga idol

guys wag kayo kukuha nung mga tig 200 pesos sa computershops...
kuha kayo yung servo type po....
we need avrs po...

hindi po dahil nagtest tayo using multimeter na hindi po fluctuating ang kuryente hindi na po magflufluctuate yan... minsan po nagflfluctuate mga appliances natin pag umuulan... or nagbukas kayo ng ibang appliance na... matakaw sa kuryente.. like your aircondition, waterpump or minsan.. pag tatakbo compressor ng ref.

best po ang avr...
it will protect your appliance.. tumaas man or bumaba ang kuryente... pareho pong importante yun... dahil parehong nakakaikli ng buhay ng appliance natin ang mga yan.. hindi po dahil ayos pa gamit natin sa mahabang panahon ay hindi sila nabubugbog... sayang po kasi appliance natin na galing sa hard earned cash...

habang may avr.. kuha nadin kayo individual switch surge protector.. para masaksak niyo din sa avr niyo dvd and htib niyo.. hehe
siyempre ako ang pm niyo!!!

Gud day peeps! newbie lang po.. ask ko lang po kung ano pong mas ok gamitin kung AVR for pc or yung AVR na nabibili sa ACE hardware? thanks!

Jay82 · « **Reply #27 on:** Feb 11, 2011 at 10:40 AM »

@JustinJao
Someone already mentioned .. di maganda class yung mga freebie na AVR na binibigay pag bumili ka ng PC ..

sa ACE i recommend Zebra & Panther brand but its pricey..
you can get other brands na Heavy duty/Servo type w/ time delay way cheap somewhere else ..

try to visit http://www.tipidpc.com/ratings.php?username=dfa172001 or PM..
I think meron din sya account here sa pdvd with Username "dfa172001"

The Sainth · « **Reply #28 on:** Feb 16, 2011 at 07:31 PM »

For me its better to have.Both the panther cost P500 at Ace hardware.

JustinJao · « **Reply #29 on:** Feb 17, 2011 at 09:35 AM »

Mga Sir, pede rin bang gamitin yung AVR sa aircon (110v, 500w)? nag-inquire ako sa ace mas preferred nila yung transformer kaso mejo may kamahalan.. kung sakali sana na tataasan ko na ng wattage pagbibili ako ng AVR (1500 - 2000 watts) para magamit ko na rin sana sa aircon. thanks for the advice..
