4 FAQs about Uninterruptible power supply battery is always charged

What is an uninterruptible power supply?

One of the most frequently asked uninterruptible power supply questions and answers involves the switchover time to battery power. Most UPS systems switch to battery power within milliseconds (typically 4-8 milliseconds), which is fast enough to prevent any noticeable interruption in most electronics.

How does a UPS (uninterruptible power supply) work?

A UPS (Uninterruptible Power Supply) works by acting as a bridge between the main power source and your critical devices. It continuously monitors the incoming power and charges its internal battery while operating on AC power.

What happens if the battery in a UPS goes out?

In an uninterruptible power supply (UPS), the connected equipment is always powered by the UPS's inverter, which runs off the DC bus. If the battery goes out, the inverter continues to supply power, but it will be drawing from the rectifier instead. There is zero transfer time to the battery.

What makes a UPS uninterruptible?

Of the three main subsystems, the battery is what makes the system “uninterruptible”. Depending upon the system design, the battery can constitute as much as 50% of the cost of the UPS. Without a reliable battery, the operation of the entire data center can be put at risk.
