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.

What are the different types of uninterruptible power supply systems?

In this blog, we’ll explore the different types of uninterruptible power supply systems, how they differ in operations, and the levels of protection they provide your critical load. The three most common types of UPS systems are standby (offline), line-interactive, and online double conversion.

What is a static uninterruptible power supply (sups)?

The static uninterruptible power supply (SUPS) basically consists of four major blocks. They are the battery rectifier/charger, battery bank, inverter and the transfer switch. The rectifier/charger receives the normal alternating current (AC) power supply, provides direct current (DC) power to the inverter, and charges the battery.

What are the requirements for power supplies and ups in critical infrastructures?

Specific requirements for power supplies and UPS systems in critical infrastructures concern reliability, robustness, and security: UPS systems ensure an uninterrupted power supply during power outages and enable an orderly shutdown of systems during prolonged outages.
