1.   VOLTAGE REGULATORS Series 600-5000 VA    


Most of us heard about the word of AC voltage regulator in our daily lives. We know that it is equipment attached to the television, to our computer or to the deep freezer.

Automatic AC voltage regulator or AVR is a wonderful invention of science, which is an electric device designed to regulate and maintain a constant voltage. The main working of an AVR depends upon the laws of electromechanical physics. It consist of many active and passive electrical components like relays, capacitors MOV, diodes and microprocessors that work in together to provide rectified and constant ac voltage to the load.

There are many appliances in our homes and office which need stable electric power for their running and there might be some damage to the whole electric appliance if there comes any variation in the input current and voltage. Sometimes this may be fatal also but electricity is a very merciless killer due to Brownouts.

What is a brownout?
A brownout is a drop in voltage to your home's electrical system.

Unlike blackouts, you still have power, just less of it. Think of a brownout as the opposite of a power surge.

Brownouts typically last from a few minutes to a few hours. They get their name from the color they turn your lights (a dimmed brown instead of brilliant light).

What causes brownouts?

There are 2 main sources of brownouts: external (outside your home) and internal (inside your home).

External causes of brownouts include:

- Power grid problems (too much demand and not enough electricity)
- Power failure at power plants
- Intentional throttling of electricity during peak demand

Internal causes of brownouts include:

- Too many electrical appliances on a single circuit
- Inadequate wiring for a large appliance (like an air conditioner, freezer or refrigerator)
-Bad wiring in the home

Are brownouts bad for my computers (and other electronic appliances)?

Don't take brownouts lightly. The irregular power supply during the brownout can ruin your computer and other electronic devices.

Electronics are created to operate at specific voltages, so any fluctuations in power (both up and down) can damage them.

Also, when your power eventually comes back, the voltages wildly bounce around for a moment (power surges). Those fluctuations can also harm your electronic devices.

How you can protect your electronic devices and appliances

To avoid any mishap to the electric appliances, which may arise due to any variation in the voltage or current supply, a voltage stabilizer is essential to be used a complement to other electric devices.
