UPS Units allow the devices to be shut down safely, while protecting key data against sudden power failure. Unexpected power shortage, as well as voltage dips or brownouts, may lead to the loss of materials in process production lines or the contents of your HDD or damage the components, ultimately causing irreversible changes or losses.

UPS units are used in powering sensitive automation and control components, workstations, technological process management centres, or for industrial data processing.

Below are the main classification of UPS based on their function:

The basic group contains offline devices ranging from 400 to 1,000VA, ensuring elementary level of security, usually by monitoring input voltage. Despite that, the time required to start backup power is relatively long and lasts up to 100ms, which means that more sensitive equipment will turn off. Simple construction of offline UPS units makes them the cheapest group of products.

Another group of UPS units, using the line-interactive technology, is most widely spread among consumers. In terms of construction, they are based on offline UPS units, but due to certain modifications, they also control the frequency and supply voltage, as well as phase angle. Switching is fast and synchronised with the power grid. Using the AVR automatic voltage regulator extends voltage range in network mode.

The most technologically advanced group comprises online UPS units, which operate within the range of 10 to 200kVA, depending on the model. In the case of these power supply units, the double conversion of supply voltage makes the output voltage completely independent from the incoming utility power. This series of UPS units ensures galvanic separation from the power grid, completely eliminating any noise. A distinctive feature of this constriction is the continuous operational mode of the inverter and the rectifier, which in case of power shortage ceases to charge the battery. Advanced construction and ideal sine wave voltage are reflected in the price, and make these the most expensive solutions on the market.

The parameters of UPS units are adjusted to user requirements and their operating time is determined based on the nature of the load. Typically industrial devices are characterised by high active power consumption, therefore despite their simple construction, power supply units dedicated to such devices are resistant to frequent heavy in-rush currents. Whereas transformer-based units offer galvanic separation of loads from the grid and the batteries. Factors that should be considered when selecting a UPS unit include:

It should be noted that due to their capability of voltage conversion, UPS units are suitable for various voltage values.

If you plan to purchase a UPS, you should focus your attention on specification parameters, such as charging time, power, or number of batteries as a factor directly impacting operational time.
