6 FAQs about [Emergency power supply battery string number 4 strings]

What is a UPS battery string?

The UPS system monitors the status of the battery string, including its voltage, temperature, and overall health, to ensure reliable backup power when needed. In summary, a UPS battery string is a series of interconnected battery cells that provide the necessary voltage output to support the UPS system during power interruptions.

What is the capacity of UPS battery string?

Capacity Requirement: The capacity of the UPS battery string is determined by the total Amp-hour (Ah) rating of the cells. The capacity requirement depends on factors such as the anticipated runtime during power outages and the power consumption of the connected equipment.

Where is the battery string located in a UPS system?

The battery string is housed within the UPS system’s battery cabinet or rack, ensuring that it is properly protected and cooled. The UPS system monitors the status of the battery string, including its voltage, temperature, and overall health, to ensure reliable backup power when needed.

What is a battery in a power supply?

How many cells are in a UPS battery string?

For low-voltage UPS systems, which typically operate at 12V or 24V nominal voltage, the battery strings may consist of a single cell or a few cells connected in series. For example, a 12V UPS battery string may comprise of six 2V cells connected in series, while a 24V UPS battery string may consist of twelve 2V cells connected in series.

What is a single battery string?

A ‘single’ or ‘serial’ string has identical battery blocks wired in series. A typical string would have 32 12V 76AH batteries providing a d.c. bus voltage of 384V and a 76Ah capacity. Although normally the most cost effective, this solution has no redundancy as one battery failure will disable the whole string.
