Siemens 6EP3437-8SB00-2AY0 SITOP PSU8600 24V/40A PROFINET Power Supply

The Siemens 6EP3437-8SB00-2AY0 SITOP PSU8600 delivers a stabilized 24 V DC output at 40 A (960 W) from a 400-500 V 3AC input, with an integrated PROFINET/Ethernet interface running a web server and OPC UA server. Output is adjustable 4-28 V via potentiometer or the IE/PN interface for remote diagnostics.

Selection Notes

The 40 A / 960 W output combined with a built-in PROFINET/OPC UA interface separates this PSU8600 unit from the simpler PSU3800/PSU3400 supplies that have no network connectivity — choose it where the cabinet needs remote current-threshold adjustment or OPC UA-based condition monitoring rather than a fixed analog supply. Three-phase 400-500 V input matches larger-load cabinets already on a 3-phase feed. The adjustable current-response threshold (4-40 A) lets one unit be tuned down for a smaller sub-load instead of stocking a separate lower-current PSU8600 variant.

Applications

PROFINET-networked control cabinets, remote-monitored power distribution, and machine panels needing 960 W at 24 V with OPC UA visibility into supply status.
