Technical FAQs 4

What is an uninterruptible power supply (UPS)?

Uninterruptible Power Supplies (UPS) are installed for mitigating risks to critical infrastructure and to protect business continuity during a power outage.

Why should a datacenter use uninterruptible power supplies (UPS)?

Using uninterruptible power supplies (UPS) is the key to sustaining the operation continuity of a datacenter. To achieve the highest availability possible for a datacenter, it is vital that the UPS is equipped with fault-tolerant capability and fail-safe design for assured system reliability.

Why are uninterruptible power supplies important?

Uninterruptible Power Supplies have been an important element in critical power protection schemes. Over time many different system configurations have been developed to mitigate the risk of loss of utility power.

Which configuration is used in a UPS system?

The standalone configuration (Figure 1), is the most common configuration utilized in UPS applications because it contains fewest number of major components. This system utilizes AC power (typically utility power) and converts it to DC through the rectifier. The regulated DC power is supplied to both bank of batteries and to the inverter.
