Product Description: Siemens 6SN1123-1AA00-0AA1

The Siemens 6SN1123-1AA00-0AA1 is a 1-axis inverter power module from the SIMODRIVE 611 Universal series, designed to control a single motor in modular CNC or motion control applications. It provides a continuous current output of 25 A and is compatible with both synchronous and asynchronous motors. This unit operates as part of a complete SIMODRIVE 611 system, requiring a compatible control unit (CU) and power supply module. The module is cooled via internal forced-air ventilation and is optimized for use in industrial environments with high reliability and minimal maintenance.
