Model NGA 2000 Platform
Table 1-1. Node Count And Power Consumption For NGA 2000 System Integration
The following accessories can be used to de-
sign a NGA 2000 system
• DUAL ANALYZER ENCLOSURE
used to house two Analyzer mod-
ules for either standard or ex-
tended lengths
• SINGLE ANALYZER ENCLO-
SURE used to house one Analyzer
module and up to 5 I/O Modules.
• DUAL PLATFORM ENCLOSURE
to allow control of two independent
systems from one location
• 5 A POWER INPUT MODULE to
be used in the single Analyzer
compartment enclosure to power
the housed Analyzer module
• 30 A BULK POWER SUPPLY
which is capable of providing
power for up to 10 NGA 2000
components
The number of I/O Modules that can be housed
in a Platform or single Analyzer enclosure is
limited to five.

Calculate MLT power consumption as follows:
MLT1 ≤3.0 A
MLT2 ≤3.0 A
MLT3 (without internal power supply) ≤5.0 A
MLT4 ≤5.0 A.
2
Total power consumed may not exceed 30 Amps for interconnection to any single 30 A Bulk Power Sup-
ply.
3
MCFID must be counted as one to five nodes depending upon the number of components measured.
4
MLT must be counted as one to five nodes depending upon the number of measurement channels
specified.
