A voltage stabilizer is an instrument designed to provide constant output voltage irrespective of the changes or fluctuations in the input, i.e., the supply voltage. Stabilizers are also referred to as Automatic Voltage Regulators (AVR). The voltage delivered by a stabilizer falls in the range of 220-230V for single phase mains and 380-400V for three-phase mains.

In Chennai, power cuts and voltage fluctuations are very common. Hence it would be foolishness to operate costly appliance without a voltage stabilizer in Chennai. Why is a stabilizer considered necessary? Let us have a look at the technical side.

Usually, all electrical appliances are designed for a wide range of input voltage. Based on the sensitivity of the components used in them, the working range of each appliance is limited to a certain value. For example, some appliances can work with in ± 10 percentage of the rated voltage while the tolerance range of some other appliances is ± 5 percent. But the fluctuation in voltage which happens due to faulty transformers, defective electrical lines, lightning, thunderstorm, etc. may go beyond the tolerance range so that it may damage the appliances.

Devices which work in over-voltage for a long time may experience the damage of winding insulation, load disturbance, reduced life, etc. It will also affect the connected cables and associated devices.
Similarly, under voltage would cause overheating of the devices, more current usage, poor performance and sometimes termination of its functioning as such.

Not taking any measures to deal with voltage fluctuation and operating costly electrical appliances in widely deviating voltage ranges would result in huge losses. Whereas, buying a good voltage stabilizer and connecting the appliances to it other than connecting to the mains directly would ensure safe operation and long life of your appliances.

Different Types Of Voltage Stabilizers, Chennai

Voltage stabilizers are available in different types. Initially, the stabilizers had to be operated manually. Later on, with the advancement in technology, automatic stabilizers came into existence. The presently available Servo voltage stabilizers in Chennai are usually fully automatic with a lot of attractive features. The following are the different types of stabilizers based on the scientific principles involved in their operation.

Relay type

Relay switching is the technique used in relay type stabilizers. They consist of rectifiers, amplifiers, micro-controllers, transformers, and a collection of relays. The accuracy of output voltage ranges between 5 and 10 percent of the desired value. Such stabilizers are generally cheap and are lightweight. They are preferred for those applications which do not require high precision output voltage.

Servo-controlled type

This type of stabilizer utilises a servo motor for voltage regulation. Other components are an autotransformer, a buck-boost transformer, a driver for the motor, micro-controllers or microprocessors involved control circuit, etc. Servo-controlled voltage stabilizers deliver output voltage which is highly accurate. Even very high deviations in input voltage get corrected to the most appropriate voltage required. This type of stabilizers can be used in both single phase and three phase mains. Routine maintenance is required for such stabilizers.

Static voltage type

Static voltage stabilizers consist of a circuit which acts a power electronic converter. They provide even better accurate results than servo controlled stabilizers. They also contain transformers, microprocessors, and controllers. Static voltage stabilizers can be made in very small sizes, and they require no maintenance as well. Hence this type of stabilizers is in more demand compared to the other ones.

Tips On Choosing The Right Voltage Stabiliser, Chennai

What are the factors to consider before buying a stabilizer? Here are the most important ones.

•  Study the power and voltage specifications of the device for which you are buying the stabilizer for. It would be there in the user manual provided while buying it.
• The rating of stabilizers is in KVA. So if the wattage rating of the instrument is not given directly in the manual, just multiply the voltage by the maximum current, and you will get the wattage value.
• Do not go for a stabilizer with the exact tolerance range of a device. Always keep some extra margin for safe operation. This would also help in future if more devices are to be connected to the stabilizer.

Keep the points discussed here in your mind and choose the best voltage stabilizer which is perfect for your requirement!

People invest big money in appliances and devices but most often forget to secure their devices from power outages. A good UPS can take care of your precious devices by giving your extra time to close applications and save files. But this is not just the only task it performs. There is more to it. UPS and power surge protectors are a must have in your office IT infrastructure. Thanks to the manufacturers of Online UPS in Chennai, the right protection is available from all types of power issues.

Helps Manage Power Fluctuations
UPS brings sufficient power to your devices to ensure it does not fluctuate much. The surge protectors take care of the basic power conditioning. It can protect your devices from power surges and save your business from blackouts and power spikes. The quality of power conditioning depends on the quality of the UPS devices, the higher the quality, the better the services. A computer can be damaged due to frequent power fluctuation. Power supply sending variable power to the computer can damage the components leading to downtime and poor productivity. Computer failures due to power fluctuations are hard to define and can lead to failure of hard drives, RAM and CPU.

Power Backup
UPS protects files from getting corrupt. Though, cheap UPS does promote efficient backup till the battery lasts. The computer exposed to sudden power loss can result in restarts leading to corruption of file system. It can also destroy the operating system wiping away vital information from the computer. To bring the computer back to working condition hiring a professional data recovery expert becomes necessary and this comes at a big cost. Therefore, the best alternative would be to prevent such situations from arising by investing in a good UPS system.

Online UPS Dealers in Chennai Offer All Types of UPS Units

The UPS units from Dealers in Chennai can be categorized into three types based on the design principles.

Standby UPS unit: This is the simplest among the three. It charges the battery and waits for the power outage to happen. Once the power drops, the UPS switches on mechanically. It takes about 20-100 milliseconds to switch on, which is determined as the tolerance threshold level for most of the electronic devices.

• Line Interactive Unit is similar to Standby UPS but comes with a transformer. The special transformer gives added benefit to the UPS unit during blackouts. Line Interactive unit can come handy for people who live in areas that are shrouded by frequent line voltage issues. It is worth the investment.
•  Online UPS is the priciest among the three, as it needs extra circuitry. The UPS unit works in isolation with the wall power. Instead of taking over once the power is out as the other two types of UPS, this one filters the wall power with the help of a battery system. The electronics run off the battery bank, and there is not even a millisecond interruption caused due to power loss or voltage fluctuations. It functions more like a firewall between the device and the wall power, stabilizing the electricity needs of the device.

Which Is Better? Comparison Between Surge Protector And UPS In Chennai

Still confused whether to buy a surge protector or UPS, check this out. The choice purely is based on the circumstances. For large establishments that want to preserve their systems from all types of power fluctuations, UPS is the right choice. On the contrary for those home computers that occasionally run for web browsing or other personal use, a surge protector can be a better option.

While buying a UPS from online battery dealers in Chennai, people have to give priority to data protection and resource protection, instead of focusing too much on security. Both data destruction and data falling in wrong hands are dangerous. A reliable & reputed UPS manufacturer can protect your data and the hardware against power odds; you can heave a sigh of relief with a superior quality UPS.
