avr electric consumption

question. gaano kalakas ang consumo ng kuryente ng 1avr? does it also consume power if its left on, but the equipment attached to is off?

Yup, it will consume energy kahit wala load, kaya nga sya warm. If my load naman, depende ang consumption nya sa load mo, mas mataas ang dadaan na current, mas mataas rin siempre losses.

Yes it does. Any electric/electronic device as long as the circuit is complete and electrons are flowing. Because energy neither can be created nor destroyed but converted to some other forms of energy. Example is the resistor with a semiconductor LED driving the power indicator of the AVR where electron flows to the material some are converted into light others are consumed by friction producing heat. The power supply of the AVR may come in a form of transformer where voltage is converted by induction, again not all energy are induced because there will be losses somewhere in the material and some in a form of friction=heat. The "plugged" equipment could also be using a small circuit for powering/snoozing the equipt.

If the fine print doesnt show current draw on standby use, one way of accurately measuring the consumption is thru the ammeter connected on the mains. A small computer AVR should be in milliampere range standby mode.

Another perspective is the use of the electronic component known as transformer by any electronic device like an AVR

The function of a transformer in any electronic device is to step down the 220VAC to a lower AC voltage (typically 12VAC) before its converted to DC voltage required by the rest of the electronic components of the AVR. Its made up of 2 coils, the primary & the secondary. The primary is connected to the 220 outlet & the secondary is attached to the AC to DC conversion circuit of the AVR

If the power switch is not located between the 220 plug and the primary coil of the AVR will continuously consume electricity if its kept plugged because there is a complete circuit between the 220 outlet and the primary coil of the AVR transformer

Yes it does. We had a very old AVR that used as much as 10 watts with no load.

the AVR is a generic one thats being used for computers. i think its 500watts. so tama ba pag naka on, depende sa load ang consumed electricity? kung laptop ang naka saksak, so mga 65w lang consumption and not 500w ?

ang isip ko kasi, pag naka on ang avr ko, automatic 500w ang consumption, regardless of the appliance that is connected.

Di naman. Ang AVR, pag sinabi X watts, yun ang kaya niyang i-handle. So kung 500 watts AVR, hanggang 500 watts ang kaya niya.

does this mean that if the switch is located between the 220 plug and the primary coil the avr is not consuming electricity even if its plugged in the 220 socket?

That is correct bro,- no electricity consumption as you cut it off from the main.

It is just like plugging in a plain extension (outlet) without any load...

Vampire consumption (current term) is mainly due to the transformer (hysteresis)....

One more thing about AVR do you even wonder why it is offered for free by most computer shops?

Because most AVRs are a sham, meaning it doesnt work as an automatic voltage regulator. Its a simple pass through circuit with surge suppressor

An AVR is supposed to maintain a certain voltage which is 220VAC. Since by nature electricity provided by electric utilities fluctuates. Its the job of the AVR to keep it stable in order to truly protect your computers. When AC voltage drops below 220 the AVR push it up back to 220 and vice versa

A true AVR is one that employs a variable transformer. When outlet voltage drops the variable transformer of a true AVR will step up the output voltage and vice versa
