What an AVR Really Does For You
An AVR is located in more than one place in your home. You see it in the living room beside the Plasma TV, you see it in your room beside your desktop computer, and you see it in the kitchen beside the refrigerator. At the office, you see it in each working station beside their computers. It somehow became a general knowledge to buy it together with an appliance people value. And everyone also makes it a point to turn it on first before using the appliance plugged-into it. Butwhat really is an AVR? And why spend more money to buy it after already purchasing a good quality appliance?
An Automatic Voltage Regulator is an electronic device or circuit that maintains an output voltage to be consistent to its load current. This is necessary because the voltage delivered to your home and mine may sometimes fluctuate which can cause serious damages to your appliance; if not completely destroying it. Fluctuations in power are brought about by so many factors. Some of these may be poor power regulations, electrical surges due to lightning, and many others. An AVR however, has a servomechanism inside that hunts the accurate voltage when surges happen in order to maintain the needed voltage level that ultimately protects your appliance.
Now you may ask, why not use an AVR in all my appliances? This friend may be a logical question but an impractical one. An AVR is usually necessary for appliances and equipments with electronic devices inside that may be sensitive to electrical surges. Examples of which are flat screen TV’s, audio/video equipments, computer systems, modern refrigerators and similar items. Simple home appliances that do not contain sensitive electronic devices like electric fans, blowers, portable radios, etc. do not need AVR’s.
In general, there are two types of an Automatic Voltage Regulator. One is the Relay Type and the other is the Servo Motor type. A Relay type AVR makes use of electronic circuitry like relays and semi-conductors to regulate the voltage. Servo Motor type AVR on the other hand, uses a magnetic core with a motorized servo mechanism to regulate the voltage. The servomechanism is the one responsible in switching connections in order to maintain the acceptable voltage. Durability wise, a Servo Motor type AVR is better than a Relay type as it can withstand voltage fluctuation better than the solid state Relay type which may easily get damaged.
Supplies AVRs of complete wattages namely, 500, 1000, 1500, 2000, 3000, 5000 all in Servo Motor Type. The output consists of three 220V outlets and one 110V outlet. AVRs also provide you with an added protection of a delay feature of about 3-5 minutes in order to prevent electrical surges during the appliance’s initial power supply. However, for your convenience, a quick-start button feature is also available for you to bypass the delay feature.
Some models of AVRs are fuse type. This is to protect users of the tendency of miscalculating load voltages being plugged-in to the AVR. In these occasions, the fuse will blow informing the user of an over voltage thus minimizing damage to the AVR and also to the appliance plugged-in. The user will only have to turn off the AVR, buy a replacement fuse from the available nearest hardware store, and switch back on AVR. And it works as good as new.
In addition to this, AVRs are very portable with handles that allow you to conveniently move the items to wherever locations necessary.
Aside from SVC-5000W, all models are ready-to-use. In AVRs, no need for you to assemble an outlet, a plug or a cord. In short, no added cost! For SVC-5000W however, due to its significant load and output, a qualified electrician/technician is necessary to safely install the load directly to the output terminals of the AVR by means of wires/cables.
For models SVC-3000W and SVC-5000W,AVR comes with a breaker. This breaker ‘trips’ or automatically turns off also in cases of over voltages that is too high to be accommodated by the fuse.
Now that you already know the importance of an AVR in your home, choose the AVR that can best protect your appliances/equipments.
