Rockwell Automation SD3100 DISTRIB PWR SYS SD3100 DC PWR MODULE - Manual (Page 11)

Introduction 1-3
1.1 Field Power Module
The single-phase Field Power Module is integrally mounted within the SD3100 Power
Module to provide the motor field excitation. The Field Power Module is rated 15 or 60
amps at 230/460 VAC. The 15A unit is supplied as standard. The 60A unit is available
as an option.
The Field Power Module requires a separately-ordered, separately-mounted field
isolation transformer. The Field Power Module’s AC input lines are connected through
the isolation transformer to the L1 and L3 inputs of the SD3100. The 15A module
requires a step-down transformer rated up to 7.5kVA (application dependent). The
60A module requires a step-down transformer rated 7.5kVA to 25kVA (application
dependent). All systems operate on three-phase 50/60 Hz., 460 to 660 VAC.
The Field Power Module is available in the configurations listed in table 1.2.
