Technical FAQs 4

What is an uninterruptible power supply (UPS)?

An Uninterruptible Power Supply (UPS) is a device designed to provide backup power when the primary power source fails or when voltage levels drop below acceptable limits. UPS systems are commonly used in computers, server farms, and data centers to ensure uninterrupted operation and protect digital data from power-related disruptions.

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 .

What is the difference between a UPS & energy storage?

UPS Definition: A UPS (Uninterruptible Power Supply) is defined as a device that provides immediate power during a main power failure. Energy Storage: UPS systems use batteries, flywheels, or supercapacitors to store energy for use during power interruptions.
