Siemens — Power Supply
The Siemens SITOP PSU8600 is a high-efficiency switched-mode power supply delivering 24 V DC from a 3-phase 400 V AC input with up to 20 A output current. It features an integrated IO-Link communication interface for remote monitoring of output voltage, current, temperature, and remaining service life. The unit provides selectable overload behavior (tripping or continuous current limiting) to match downstream protection devices. With an efficiency rating exceeding 93% and full electronic short-circuit protection, the PSU8600 ensures reliable DC power for critical automation systems.
