avr = surge protector?

[boybi]

for AVRs, OMNI seems to be a good brand.

[BlueBimmer]

yeah ok ang omni pero overrated ang rating nyan hehe..trust me i know, dami kami stock nyan, pati na rin akari, tailee etc. basta mga economy avr

[Picard]

Belkin's are also reputable brands like this one:

but i don't know if they have 220V versions.

over rated ba talaga?

i'm using a 500W Omni AVR. ito ang mga nakasaksak sa AVR:
Desktop with 2 DVD Writers, 3 HDDs, LCD Monitor.
800VA APC UPS (mas mataas pa yata rating ng UPS )
11W table lamp
4.1 Altec Lansing speakers
Inkjet printer
Cordless phone
and chargers of cameras/cellphones.

almost 2yrs na itong AVR sa akin.

available kaya yan dito sa pinas?

Pls explain this further. Lets say we have a laptop with fully charged battery pluged into an AVR which is then connected to the power outlet.

Scenario 1. If the voltage suddenly goes up to 230 Volts for whatever reason then the AVR should protect it by regulating the voltage, keeping it at 220V. Is this correct?

Scenario 2. There is a lightning storm, then the AVR is pretty much useless? Shoudn't tha AVR's fuse blow therefore protecting the computer?

Scenario 3. Power goes out and returns after a few seconds. You were able to continue working bec of the battery. Is there risk to your computer from the sudden inflow of electricity?

Scenario 1: Theoretically, yes. Note that voltages of 200-240 V are perfectly "normal" and expected (the voltage is allowed to vary by 10%). Of course, equipment may be more sensitive than the "margin of error" allows, this is where an AVR is in order.

Scenario 2: The best protection in a lightning storm is taking out the plug. Remember that lightning can jump the gap between the cloud to the ground. It'll have no problems with that centimeter gap between two ends of a fuse/breaker. Surge protectors however, may guard against sudden "normal" spikes (motors coming on, for example, produces voltage spikes).

Scenario 3: With a good UPS? No.

kaya sa kaya pero like what we always tell our customers...pag ganyan karami sinaksak mo at masira ang avr o may mangyari..do not come back here and demand for replacement or put the blame on us. pag may nagtatanong ng avr we always ask beforehand ano ang mga isasaksak nila..

i think kaya walang problema yan dahil di naman talagang 800VA ang kain ng UPS, yan ang maximum rated but not the actual consumption..on that particular setup maybe

I haven't seen one yet. When I was in the states i phoned them up and told me they don't carry 220V versions. Too bad.

sa control panel ng UPS, nasa 175W lang ang load ng UPS, accurate kaya ito?

anyway, what i like about the Omni AVR is that it has a servo-motor, unlike the cheaper ones na electronic ang pagcontrol sa voltage.

[BlueBimmer]

ahh servo type pala yan, ok yan.

karamihan kasi sa mga cheap avrs ngayon puro electronic na kaya madali masira pag overload hehe
