1.2.2 PACS Unit
The Power Analysis and Conditioning System provides the required electrical and mechanical
interface between the AC source, the user‟s equipment under test and the data acquisition PC
system. This allows all signal connections to be made easily and conveniently. The PACS can be
single phase or three phase, depending on the CTS system configuration in use. Single phase
PACS units may also contain the required reference impedance for making flicker measurements
when a power source without programmable impedance is used. PACS units with the reference
impedance built-in have a Bypass and Flicker mode that is controlled through the A/D card digital
I/O from the CTS 3.0 software. The front panel controls for Bypass and Flicker mode are
disabled. The mode of operation (Bypass for harmonics measurements and Flicker for flicker
measurements) is indicated with a set of LED‟s.
The PACS unit has several AC power input and output connections as well as an interface
connector to the PC based data acquisition system.
For higher power systems, the CTS system can be configured with the 75 A per phase versions of
the PACS unit. (Standard on 30003iX-CTS system).
