Siemens 6SN1145-1BB00-0FA1 Infeed/Feedback Power Module

The Siemens 6SN1145-1BB00-0FA1 Infeed/Feedback Power Module is a SIMODRIVE 611 power module that functions as a DC link power supply with energy regeneration for SIMODRIVE 611 drive systems, delivering about 120–156 kW from a 380–480V AC input with internal cooling for reliable operation. As an infeed and regenerative feedback module, it uses closed-loop control to stabilize the DC link in high-power industrial applications, and is installed as a drive system cabinet module in CNC machines, automated production lines, metal processing equipment, and other large-scale machinery that require precise motor control and energy regeneration. Key specs include 0°C to 45°C operating temperature, compatibility with SIMODRIVE 611 drive systems, and internal cooling to support demanding environments. Common replacements for this family include Siemens 6SN1145-1BA01-0BA1, 6SN1145-1BB00-0FA0, and 6SN1145-1BA02-0CA1.
