Technical FAQs 4

What is an uninterruptible power supply?

Uninterruptible power supplies provide power to critical loads in the event of a power failure. Unlike emergency generators, UPS systems provide power immediately, but only for a short period of a few minutes – until a backup power supply comes online or until the load completes its shutdown sequence.

Are battery-backed uninterruptable power supplies reliable?

Reliability of power sources is an increasing challenge in many sectors and battery-backed uninterruptable power supplies (UPS) are one option to protect and keep electronic equipment operating in the event of grid power failure.

What is an uninterruptible combined UPS system?

The uninterruptible combined UPS units include an economical 24 V DC switched mode power supply with an integrated charge and control unit for optimal battery management. These space-saving combined UPS systems control and monitor the connected battery modules, providing early warnings when battery life expectancy is low.

Why is the inverter rated at 100% of the load power?

The inverter is rated at 100% of the load power since it must supply the load during the normal mode of operation and also during the backup time. It is connected in series with the load; hence, there is no transfer time associated with the transition from normal mode to stored energy mode.
