Technical FAQs 4

What is an uninterruptible power supply (UPS)?

Uninterruptible Power Supply (UPS) | Schneider Electric Hong Kong, China. An Uninterruptible Power Supply system provides emergency power when the main source fails, using batteries to ensure a continuous supply. It conditions incoming power, protecting equipment from fluctuations. We offer various UPS power supply types for different needs.

Which transformer is required to provide neutral terminal to UPS system?

5.1.16 (Optional) Isolation transformer is required for providing neutral terminal to the UPS system. Detailed configuration of the isolation transformer shall be referred to the Particular Specification. Bypass mode. Under normal operation, the rectifier/charger unit shall convert the incoming a.c. mains power supply to d.c. power.

How to determine the availability of the UPS system?

batteries. 7.5 The availability of the UPS system shall be defined as the probability the UPS system is providing the normal operation and functions with the required performance. The availability shall be determined mathematically as follows: or where MTTR is the Mean-Time-To-Restore figure of the UPS system.

Does ups comply with IEC 62040-3?

5.1.1 The UPS system performance shall conform to IEC 62040-3. 5.1.2 The general and safety requirements of UPS system shall be complied with IEC 62040-1.
