AMETEK MX CTSH - Manual (Page 13)

California Instruments Revision H 13
User Manual MX Series CTSH Compliance Test System
1.2.1 AC Source Models
The CTS system is supplied with one of the following MX/RS Series programmable AC power sources:.
•
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
No other MX/RS Series power source models are supported by the CTSMXH Software. 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.
Note: The CTS systems are rated for a maximum current of 75 amps rms per phase. Damage to
the standard PACS-3-75 units can occur if higher currents are present. Care must be taken
to not exceed this rating when using the system directly with the utility line or with the
higher power source configurations.
1.2.2 PACS-3-75 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-3-75 unit has several AC power input and output connections as well as an interface connector
to the PC based data acquisition system.
1.2.3 PC Based Data Acquisition System (updated for new PCI data acquisition)
All measurements required for IEC testing are performed by the data acquisition system that resides on the
user’s PC. The measurement card needs to be installed in an available slot and the software needs to be
installed. All signal connections between the PC and the PACS-3-75 unit are made with a single 37 pin to
68 pin a supplied with the system.
The following data acquisition cards are supported by the CTSMXH software:
CI400PCI PCI card NI 6032/4E. No longer provided on new system shipments but still
supported by MXCTSH software revision 1.0
CI401PCI PCI card Exacq Technologies CM2110 PCI A/D card, 250 Ks/sec for single phase
systems (P/N 250803)
CI403PCI PCI card Exacq Technologies CM2210 PCI A/D card, 1 Ms/sec for three phase
systems (P/N 250797)
CI401PCI PCI card National Instruments M Series PCI-6220 A/D card, 250 Ks/sec for single
phase systems (P/N 250821) for software version 2.0.x or later
CI403PCI PCI card National Instruments M Series PCI-6250 A/D card, 1 Ms/sec for three
phase systems (P/N 250822) for software version 2.0.x or later
The data acquisition system samples all voltage and current channels at a high sampling rate and provides
the data to the CTSMXH Software for further processing. The PACS-3-75 provides a single voltage input
channel and three current input channels for each phase, to the PC. This allows for current range changing
