UPS, Uninterrupted power supply is basically a standby power device. Not only this, but with the advancement in technology it has outgrown as a protector of computer system and its data. An uninterrupted power supply primarily protects the important and heavy data in computers at times when power fails.
UPS basically resides between the critical load and ac power supply. One can avoid loss of important data due to sudden turning off the computers. However, this is caused due to abrupt voltage changes. Using a good quality pure sinusoidal wave UPS can overcome this problem as sufficient back up of electricity is provided.
Since equipments like computers store very important and official data and are sensitive to sudden voltage surges need to be protected with this device. If one fails to protect the appliance with UPS, the data stored there gets completely corrupted. But, this uninterrupted power supply system provides you a stable and fixed voltage. Besides, a frequent variation often considered as fluctuations is noticed in the voltage. This can impair the working of the appliances. Moreover, the data stored in that appliance gets totally corrupted.
Inverter is a device that any UPS would include for the effective and continuous performance. It is basically used in transforming of DC voltage into AC voltage. And so depending on that, UPS are categorized in three main types.
Application where continuous and fixed power supply is needed, on line UPS are employed. This type of inverter is independent of voltage and frequency fluctuations and hence often known as voltage and frequency independent. Purely a sinusoidal output is received with such UPS. Servers, networks, labs and industries find the application of on line UPS, the most.
As compared to the on line UPS, interactive or off line UPS are less sophisticated uninterrupted power supply. These are applicable for home appliances protection and don\’t remain active all the time.
A battery is also provided with the UPS. When there is a power outage, the energy stored in the emergency battery keeps the power supply flowing to equipment for a small amount of time, normally for about 20 minutes. work when power goes off.
UPS is highly efficient device possessing the efficiency of about 80%. Additionally, these are a perfect combination of both reliability and low cost. The output provided by these is smooth and distortion free. One should take electricians help while installing them at your places.
