1.2 Compliance Test System Description
The California Instruments Compliance Test System is a complete IEC AC power test system
that covers many of the IEC regulatory test standards involving AC and/or DC powered
equipment.
To ensure maximum flexibility of both the hardware and the software required to create a turn-
key system, the CTS system uses a modular structure consisting of the following components:
• Programmable AC power source. The AC source provides precise, isolated and low
distortion AC power at the user specified frequency and voltage. The AC source also offers
over current protection to avoid damaging a load that exhibits a failure. The AC source can
either be a single-phase or three-phase unit. For some DC tests, iX Series based CTS
systems also provide DC output.
• Power Analysis and Conditioning System unit. The PACS unit creates the electrical and
mechanical interface between the AC source, the Equipment Under Test (EUT) and the PC
based data acquisition system. It provides the necessary signal conditioning and isolation for
the acquisition system.
• PC Based data acquisition system. The data acquisition system uses a fast Analog to Digital
conversion card that plugs into an available card slot in the user’s PC. The CTS 3.0 software
controls all aspects of the A/D card and processes the data for IEC test purposes.
• CTS 3.0 Software. The CTS 3.0 software implements the harmonics and flicker IEC tests. In
addition to the CTS 3.0 Software, the California Instruments CIGUI32 (Series I iX) or CIGuiSII
(Series II iX) Windows program is used to control the AC and DC source used and to
implement those IEC tests that run on the AC source, specifically the IEC 61000-4 immunity
tests.
The AC source output is connected to the rear of the PACS unit. For single-phase applications
the user only needs to connect the EUT to the IEC/77 connector located on the front panel of the
PACS unit to set up his test hardware. For three phase applications the rear terminals are used.
All user interactions with the CTS system are accomplished through the CTS 3.0 and CIGUI32 or
CIGuiSII software. There are virtually no front panel controls required to operate the CTS system.
