Suppose you are working on an important presentation in your desktop and all your work gets erased when the electricity gets cut off. Well this is when you need an urgent power backup. But, you don’t have it with you, of course. You should be prepared, rather than regretting it later, If you don’t want to face this situation. Why not find a perfect solution for such situation right now? UPS is the solution for all these problems. The online UPS is ideal for environments for equipment that is very sensitive to power fluctuations or where electrical isolation is necessary. However, the online UPS unit was once only used for very large installations of 10 kW or more, with the advances in technology.
How it works?
When the electrical power cuts or drops to its lowest voltage level Uninterruptible power supply (UPS) is a device that provides battery backup. Online UPS is the most advanced inverter and the computer equipment is never receiving power directly from the AC outlet as it is continuously providing power from the battery. Where the UPS output is always supplying current to the load is an online UPS system. As batteries are always connected to the inverter in the online UPS and it converts incoming AC power to DC, and then back to AC, so transfer switches are not necessary.
Keeping the power steady the rectifier turns off and the batteries starts supplying the DC While there is a power loss, which is converted and supplied to the load by the inverter into AC. the rectifier gets back to its work carrying most of the load when the power is restored and charging the batteries, to prevent the electrolytes of the batteries from billing off, the charging current would still be limited and from the high- power rectifier batteries getting overheated. This creates an electrical firewall sensitive electronic equipment and incoming utility power.
What are the advantages of online UPS?
- Between the main supply and load it provides isolation ensuring safety from any kind of accidents.
- The load doesn’t experience fluctuations in voltage, since inverter is always ON and making it low maintenance cost and high performance equipment, it increases the lifespan of the load.
- In the circuit Voltage regulation is better
- All the disturbances of supply are absent in the output such as blackouts, brownouts, spikes, etc.
- Since inverter is always ON Instant transfer time.
Where and why are they used?
The online/Double-conversion UPS systems are well suited for the following purposes due to these advantages.
- Mission-critical IT equipment to protect
- To protect High-end servers and data center installations
- To save from damage caused by a power blackout, voltage surge, voltage sag, over voltage, frequency noise, voltage spike, frequency variation, or harmonic distortion to the advanced network equipment.
- Can be used in similar other motor control applications and Induction motor drives
- From sudden damage or accidents to keep large telecom installations and storage applications.
- Can be useful for medical equipment and Intensive care units.
Total cost of ownership is generally lower due to longer battery life but the initial cost of the online UPS may be higher. When the power environment is “noisy” the online UPS may be necessary, when protection of sensitive IT equipment loads are required, when utility power sags, outages and other anomalies are frequent or when operation from an extended-run backup generator is necessary.
