15.3 PACS Specification
The PACS unit creates the mechanical and electrical interface between the AC source, the EUT
and the PC. It provides the necessary isolation and signal conditioning to perform the
measurements needed.
PACS units are available in single and three phase configurations. Single phase CTS systems are
supplied with a PACS-1 single phase unit, three phase CTS systems are supplied with a PACS-3
or PACS-30-75 three phase unit.
The following specifications apply to the PACS units.
