How Does An Uninterruptible Power Supply (UPS) Work?
Uninterruptible power supply

How often do we face power supply problems? Uninterruptible power supply (UPS) is the solution. It protects the device from lightning strikes and sudden power supply problems. In case the voltage drops to an inadmissible amount or when the regular power source fails, UPS acts as a source of alternate power or backup power. 

Uninterruptible power supply (UPS) allows a well-ordered shutdown of all the connected devices and the computer itself. The basic components of UPS are Inverter, charger /rectifier, static switch, and battery. The static switch helps to replace utility power with no additional transfer time and the load doesn’t get interrupted by a shortage of power supply. The inverter ensures there are no problems caused as the voltage fluctuates.

Trust The Professionals!

Many companies rely on Uptime Systems Australia to receive ongoing technical support. UPS makes sure that the computer is protected against various problems such as voltage sags, frequency differences, voltage spikes and surges, and also total power failure. 

UPS comes very handy, especially in telephone exchanges, computer centers, and big companies for industrial process control. The uninterruptible power supply solution can provide essential benefits to the business as well, such as remaining productive, keeping your deadliness, and also protecting your equipment. 

Here are different types of UPS and how they work:

Standby

This is the most basic type of UPS, It is powered directly by the input power. When there is a voltage surge, voltage sag or a blackout, the UPS falls back on battery backup power. Here the operating principle is that the AC input is connected parallelly with the inverter in a standby. There are certain limitations with this model, as it lacks a real static switch it functions best on consumer electronics, security systems, and entry-level computers but for more revolutionary systems such as telephone exchange, this model is incompatible with the performance.

Line Interactive

This is the most popular and cheapest UPS available. Here the operating principle is that the AC input is connected parallelly with the inverter in standby and it also makes sure that the battery is charged. As the frequency regulation is not possible in this model, it is specifically used for low-powered ratings only. This model is used for gaming systems, network equipment, home theatre electronics, and consumer PCs. This model may require a higher current circuit compared to a normal circuit design as it may need more current than normal in low voltage conditions. 

Double conversion (online)

The operating principle of this model is that in between the application and the AC input, the inverter is connected in a series. Although the basic technology is similar to that of the standby model and line-interactive model, it is more expensive than the rest because of the supreme components used inside and this model is also very essential for industrial settings. This model also provides an electrical firewall between sensitive equipment and incoming utility power. 

Conclusion

Unexpected power problems can cause data loss or serious business disruption. UPS takes the load in such events and protects the system. The above points clarify how it works.
