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 MX Series or RS90 series AC power source. The AC source provides AC power at the
user specified frequency and voltage. The MX/RS Series AC source also offers over current protection
to avoid damaging a load that exhibits a failure. The MX/RS power source is a three-phase unit.
The following power source configurations are currently supported on MX-CTSH systems:
•
MX30-3Pi-CTSH
•
MX45-3Pi-CTSH
•
MX60-3Pi/2-CTSH Two cabinet MX master/auxiliary power source.
•
MX90-3Pi/2-CTSH Two cabinet MX master/auxiliary power source.
•
RS90-CTSH
This user manual generally refers to the power source as a MX45-3Pi model as it is most common.
Where relevant, the other power source system configurations will be covered specifically. In general,
operation of the CTSH system is the same for any of these four configurations.
•
Power Analysis and Conditioning System unit. The PACS-3-75 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 CTSMXH Software controls
all aspects of the A/D card and processes the data for IEC test purposes.
•
CTSMXH Software. The CTSMXH Software implements the harmonics and flicker IEC tests. In addition
to the CTSMXH Software, the California Instruments MXGUI 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 EN 61000-4
immunity tests.
The AC source output is connected to AC input terminal at the rear of the PACS-3-75 unit. The PACS-3-75
AC output rear terminals are used to connect the EUT. All user interactions with the CTS system are
accomplished through the CTSMXH and MXGUI software. There are virtually no front panel controls
required to operate the CTS system.
