Technical FAQs 4

What is an uninterruptible power supply (UPS) system?

Power distortions such as power interruptions, voltage sags and swells, voltage spikes, and voltage harmonics can cause severe impacts on sensitive loads in the electric systems. Uninterruptible power supply (UPS) systems are used to provide uninterrupted, reliable, and high-quality power for these sensitive loads.

Why do we need uninterruptible power supplies?

However, during transmission and distribution, it is subject to voltage sags, spikes and outages that can disrupt computer operations, cause data loss and damage equipment. The uninterruptible power supplies protect the connected equipment from power problems and provide battery backup during power outages.

What is a voltage independent ups?

• VI (Voltage Independent): this is the UPS in which the variations in the power supply voltage are stabilised by electronic/passive regulation devices within the limits of routine operation .

What are the input dependency characteristics of an AC-output ups?

Input dependency characteristics -- Voltage and Frequency Dependent (VFD), Voltage Independent (VI), and Voltage and Frequency Independent (VFI). Rated Output Power - from less than 1500 kVA to greater than 10,000 kVA. The key criteria are shown below for AC-output UPSs that operate in a single input dependency (i.e., VFD, VI or VFI).

TIP technical series | Edition 3 | Modelling

The output of a UPS with VI classification depends on the frequency of the AC voltage input, and the output voltage must remain within the prescribed limit voltage values.

TIP technical series | Edition 3 | Modelling

Technical Series Edition 3AAA"VFD" (Voltage and Frequency Dependent):"VI" (Voltage Independent):"VFI" (Voltage and Frequency Dependent):2. Integration of UPS systems in power distribution networksUPS3. Simulation of UPS systems in SIMARIS designUPS systems with VFD classification must pro-tect the load against power failure. In this case, the UPS output is influenced by changes of the input AC voltage and the fre-quency, and it is not suitable for assuming additional correction functions which may arise from the application of an autotransformer.See more on assets.new.siemens
