Overview
The Allen-Bradley 1394-AM03 is a servo axis amplifier module engineered for digital AC multi-axis motion control systems. As part of the 1394 series, this module converts DC power supplied by a system module into variable AC voltage to drive servo motors with precision. This unit is offered as used surplus inventory, making it cost-effective for facilities seeking replacement or spare components. The 1394-AM03 is compatible with Series A and B systems and integrates seamlessly into modular 1394 system configurations via slide-and-lock connectors.
