Why UPS?

We have all witnessed power outages. In addition, severe fluctuations also affect the power network. In addition to wasting time, power outages can cause the loss of sensitive information, damage to electronic equipment, and even their failure.

Electronic devices are very vulnerable. Factors such as sudden power outages or severe voltage fluctuations can cause irreparable damages to the electronic devices. In this case, UPS can reduce the possibility of damage to almost zero.

What is ups?

UPS (uninterruptable power supply ) is an electronic power supply which it’s superior task is to supply the required power without interruption.

In fact, when the mains is suddenly cut off or some severe fluctuations on the network became a threat for various reasons, UPS provides you very favorable quality power to prevent damage and loss of sensitive information.

Application of UPS

UPS is mainly divided into 3 sections: Stabilizer, Charger and Inverter.

In the case that the mains has normal frequency and voltage, UPS uses the same power input to feed various equipment. If the Mains fluctuates for various reasons, the UPS will remove all the fluctuations using its stabilizer. In this case, the UPS stabilizes the Mains using a stabilizer and produces 220 V electricity at its output.

UPS types and their differences

You can find a complete comparison in the “ Comparison of UPS models “ article. But in here we also have a review.

In general, there are 3 types of UPS in the market: online, offline and line interactive. Even though the overall operation of these UPS is common, they have different technologies.

The main task of the UPS is to supply the required electricity for the equipment’s load. In addition to keeping the output power stable, the UPS eliminates any noise and fluctuations and provides the required power to sensitive equipment during a power outage.

In addition, another purpose of UPS is to prevent damage to electronic devices and protect them during sudden power fluctuations, voltage changes, and power outages.

Online UPS :

The function of online UPS is that initially the mains is rectified by the rectifier of the device and turns into DC and charges the batteries. Then it is converted back into 220V AC by the inverter which is active at any time and provides requested power for the protected equipment.

With a power outage, the inverter immediately feeds the load without interruption using the energy stored in the batteries. for sensitive devices, online UPS is an absolute essential. Online UPS are suitable for all types of usage and truly are the most efficient among all types of them.

Offline UPS:

Offline UPS offers only basic features; Such as protecting the electronic devices against unwanted high voltage and charging batteries. These types of UPS normally use mains power, but as soon as the power failure, they transfer battery power to the output.

switching speed in this type is about 5 to 10 milliseconds. This period of time may seem very fast, but nevertheless it is not so fast that it can provide the instantaneous power required by sensitive equipment and may cause some unwanted damages.

It is not recommended to use offline UPS in hospitals and clinics for medical and dental equipment.

Line-Interactive UPS:

Line-interactive ups is actually Offline UPS but offers enhanced protection compared to offline uninterruptible power supplies thanks to their ability to monitor the voltage levels and correct any under or overvoltage.
