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.

What are uninterruptible power supply standards?

Uninterruptible power supply standards are established technical frameworks that define the minimum acceptable levels of safety, functionality, and efficiency for UPS systems. These standards are not arbitrary they are the result of decades of research, development, and practical field data gathered by industry experts, scientists, and engineers.

Why is a battery important for an UPS system?

UPS STATIC UNINTERRUPTIBLE POWER SUPPLIES TECHNICAL GUIDE 17 ONTENTS WWW.LEGRAND.COM Batteries are essential for the UPS system: they ensure continuity of power supply by providing energy to the inverter (for the required period) when there is no power supply . It is therefore essential that they are always connected, functioning, and charged .

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 .
