NOTE:
This guide specification covers the requirements for static UPS to provide continuous ac power to critical loads and/or to improve the quality of ac power to critical loads. The specification is intended to cover three-phase systems starting with the smallest unit at 20 kVA. The upper end for a single module is around 750 kVA; however, parallel systems can have a larger total output. This guide specification is intended to be used with individual UPS units which contain a single module, parallel systems of the same size module, and scalable modular UPS systems. Single phase systems are not addressed. This specification covers UPS with electro-chemical batteries. Electro-mechanical (stored energy) UPS are not addressed. White paper TSEWG TP-19 is on Static Uninterruptible Power Supplies and should be reviewed while editing this specification.
