Description
About the PSU8600
About the PSU8600
The Siemens 6EP3436-8SB00-2AY0 is a SITOP PSU8600 single-output power supply that delivers a stabilized 24 V DC output rated at 20 A (480 W) from a 400-500 V 3AC input, featuring an integrated PROFINET interface, a built-in web server, and an OPC UA server for remote monitoring, diagnostics, and configuration.

Selection Notes
The 6EP3436-8SB00-2AY0 is the single-output 20 A member of the PSU8600 PROFINET family, suited to a machine section running off one shared 24 V DC bus rather than several independently supervised circuits. Compared to the 4x5 A variant in the same series, this model trades per-branch fault isolation for a simpler single-loop wiring scheme at the same 480 W total power. The PROFINET connection with built-in web server and OPC UA server reports output voltage, current, and DC-OK state without separate signal wiring back to the controller, and the remote-reset input lets a fault be cleared from the PLC program instead of a cabinet visit. Where four separately monitored 24 V branches are needed instead, the 8MB00 4x5 A model in the same PSU8600 family covers that requirement in a similar footprint.
