Technical FAQs 4

What is an uninterruptible power supply system?

Uninterruptible Power Supply System When utility mains are not available, electricity can be supplied from a source such as a standard connected equipment UPS, which provides power supply. UPS is mostly used for critical loads and is kept between commercial utility mains.

What is an uninterrupted power supply (UPS) system?

Abstract. In the modern world, when there is a power outage or a power failure, telecommunication systems, computer systems, and many other critical equipment, such as medical equipment, require uninterrupted power to support their operation. Uninterruptible power supply (UPS) systems are used for this purpose.

Do power supplies need to be isolated?

Isolating signals is not enough to provide true isolation from noise and high voltages – the power supplies need to be isolated too. Designing an isolated power supply is often something that takes specialized skills and experience. It costs precious time and multiple iterations to get it right.

What is a transformer based uninterruptible power supply?

This protects against electric shock and suppresses harmful electrical noise. Typically, transformer-based uninterruptible power supplies are the choice for industrial environments and medical applications that tend to demand galvanic isolation.
