Access to electricity is currently a necessary condition for the functioning of every business entity, public entity and even household. This is particularly visible in the context of information technology, where any power outage or even a voltage drop may cause irreversible losses. How to effectively protect yourself against this? What is a UPS? Check it out and see for yourself!

What is a UPS used for?
The UPS (Uninterruptible Power Supply) is used to supplement energy shortages in the event of a lack of energy supply from the conventional power grid.
What are the features of UPS power supplies?
- Protection against power failures
The UPS protects devices connected to it against sudden interruptions in electricity supply. In the event of a power failure, the UPS automatically switches to emergency power, thus maintaining continuity of supply. For this purpose, the power supply uses the energy potential stored in batteries, which are, for example, elements of the battery module for the SPECLINE Series UPS power supply .
- Protection against voltage drops
The UPS regulates the voltage supplied to connected devices, preventing the negative effects of voltage drops, to which computers, servers, routers, etc. are particularly sensitive.
- Electromagnetic interference filtration
The UPS is usually equipped with a filter whose function is to reduce electromagnetic interference and noise on the power line. The device provides clean and stable power supply to all connected electricity consumers.
- Time to secure your data
During the operation of the emergency power supply, the user has time to safely close the work on his computer or server, save data, and finally check the correct functioning of devices using digital control.
- Operation in unstable power supply conditions
The UPS allows electronic devices to operate in places where frequent voltage surges occur or the power supply is unstable. Using the power supply in such conditions protects electronic circuits against damage and data loss.
UPS power supplies are widely used in homes, offices, data centers, server rooms, laboratories, and also in places where reliable power supply is crucial, such as hospitals and airports.
Which UPS should I choose?
The choice of UPS should take into account: 
a number of criteria, consistent with the needs of the institution, enterprise or household.
UPS selection criteria:
- Permissible load – determines the number of electronic devices connected to the UPS. The key here is total power consumption (expressed in watts or VA);
- Battery life – the power supply time depends on the battery capacity;
- UPS topology – there are three basic UPS types to choose from: offline (offline/standby), line interactive (interactive with initial voltage correction) and online (online/double-conversion);
- Additional functions – available additional functions (surge protection, adjustable frequency, remote monitoring and management, expandability, audible alarms) should be analyzed according to demand;
- Brand and quality – reputable brands offer better technical support and longer UPS lifespan;
- Budget – You need to find a UPS that meets your requirements while maintaining affordability.
UPS power supply ranking
Below are some power supplies, 
selected in terms of their functionality and value for money.
Ever UPS. UPS Ever SPECLINE Avr 700
The power supply was designed to protect the operation of solar systems, pumps, central heating boilers, fireplaces with a water jacket, as well as control and automation systems. This is extremely important during periods of low temperatures outside. Facilities equipped with numerous electrical and electronic installations practically lose their basic functionality as places of work and residence in the event of a power failure.
SINUS PRO 500 E emergency power supply 12/230 V (350/500 W)
Another proposal intended for emergency power supply of computer sets and servers. Power failure causes immediate switching of the operating mode to battery power. Thanks to this, the operational continuity of the central heating installation (central heating furnaces, pumps, controllers, feeders, etc.), automatic gates, automation devices and even power tools is maintained.
SINUS PRO 2200 E emergency power supply 12/230 V (1600/2200 W)
Thanks to the ability to generate a sinusoidal voltage at the output, the device can power equipment that requires inductive energy (power tools, air compressors, air conditioners, refrigerators, freezers).
The selection of an appropriate UPS should be preceded by a thorough analysis of needs and the characteristics of the equipment that will be protected. Free account registration will allow you to have constant access to all information about the products you are looking for.
