Introduction
The SA3100 AC Power Modules are variable-voltage, variable-frequency inverters for
use within the AutoMax™ Distributed Power System (DPS) environment. These
Power Modules drive 3-phase AC motors at variable speeds using pulse-width-
modulation (PWM) technology. Operation is programmed and controlled using the
AutoMax Programming Executive software (Version 3.5 or higher).
SA3100 Power Modules are available in configurations rated from 1 to 800 HP with
input voltages from 230 to 575 VAC or from 310 to 775 VDC (common bus). They are
supplied in an enclosure for stand-alone operation or open-chassis for mounting
within a suitable user-supplied enclosure. Several types of Encoder/Resolver
feedback devices are available. An interface for Flex I/O is also provided.
Figure 1.1 and table 1.1 describe the SA3100 catalog numbering scheme and Power
Module rating codes for DPS SA3100 drives.
