SIEMENS 6SN1145‑1BA01‑0DA1 SIMODRIVE 611 Power Supply Module

The 6SN1145‑1BA01‑0DA1 is an infeed / regenerative power supply module for Siemens SIMODRIVE 611‑U drive system. It converts three‑phase AC mains input into DC bus voltage for supplying connected drive power modules, and supports regenerative energy feedback back to the power grid for energy‑saving operation.

This unit adopts compact 611‑U rack‑mount design, equipped with integrated monitoring and protection circuits. It works with SIMODRIVE 611 power and control modules, widely used on CNC machine tools, machining centers and other high‑dynamics industrial processing equipment.
