    • PRODUCT OVERVIEW

      What is this product?

      The 6ES7138-7EC00-0AA0 is an AC power supply module (SIMATIC, 120/230 V AC) specifically designed for Siemens SIMATIC ET 200iSP distributed I/O systems. This product is a core component of automation control systems, primarily functioning to connect to an external AC mains power supply of 120/230 V AC (operating range 85 V to 264 V AC, frequency 47 Hz to 63 Hz) and safely convert it to the low-voltage power required by the system. This provides a continuous and stable power supply to the interface modules, electronic modules, and backplane bus of the entire ET 200iSP site.
