Q. |
What is automatic voltage stabilizer? |
| |
Stabilizer is the Automatic Voltage regulator. It regulates the output power. It produces the output in between 190V to 240V for your appliance whether the Input Voltage is as low as 110V or as high as 280V. |
Q. |
What is the function of Automatic voltage stabilizer? |
| |
Automatic voltage stabilizers are an effective solution to voltage fluctuation problems. They are designed to current a wide range of Input Fluctuations to maintain specified output voltage. The output voltage waveform is completely distortion free and the regulation is unaffected by the load power factor. |
Q. |
How can I protect the appliance from high voltage risk? |
| |
Automatic voltage stabilizer should have the high voltage protection. If the Input is going beyond the 290VAC and output is going beyond 250V in worst cases. The stabilizer should sense Input and Output condition and cutoff the output supply of the stabilizer. So In this way stabilizer protects the connected appliances. |
Q. |
What is the difference between manual & Automatic voltage stabilizer? |
| |
In case of manual voltage stabilizer, the output is corrected by manual operation i.e. if O/P voltage increase one has to rotate the switch on its own to make it down and if output voltage decreases he has to rotate the switch to make it up. Thus, if there are sudden changes in the Input voltage, it can damage the stabilizer as well as the equipments connected to the While in the automatic voltage stabilizer all the up and down process are done by automatically with the help of electromagnetic switches (Power relays) so that for the specified Input voltage one gets the specified output voltage. There is absolutely no need to make it up or down manually. |

Q. |
How will I select stabilizer rating for my home/office? |
| |
Before selection the stabilizer you need to know how much power you use. By taking an inventory of all the essential electrical loads in your house / office, and doing a basic electrical load evaluation, you can get a good idea how much power your system needs to produce. Second, you have to know about the power Fluctuations situations also that means what voltage minimum / maximum you are getting from the main A.C. supply. In brief, you have to select the Input Voltage window and the power consumption of your appliance. |
