Overview
The Allen-Bradley 1394C-AM03 is a high-performance servo axis amplifier module designed for industrial motion control and automation systems. This three-phase multi-axis module delivers up to 2 kW continuous output power and is rated for 530–680 V DC input, making it suitable for multi-axis servo systems requiring synchronized, precision motor control. The 1394C-AM03 incorporates advanced filtering and enhanced termination for improved EMI performance in demanding plant-floor environments.

Typical Applications
The 1394C-AM03 excels in multi-axis material handling systems, high-speed packaging lines, press load/unload automation, and converting operations. It is commonly used where frequent power monitoring or power cycling is required and where synchronous servo motion across multiple axes improves throughput and positioning accuracy.
Compatibility & Replacements
The 1394C-AM03 is designed as an axis module for Allen-Bradley 1394 Servo Controller systems. Up to 4 axis modules can be stacked in a single 1394 system module, allowing scalable multi-axis configurations. This module is discontinued by the manufacturer but remains available in the used/refurbished market. It is a direct drop-in for legacy 1394 systems requiring axis module replacement.
