The Siemens 6EP3323-0SA00-0BY0 is a SITOP PSU3600 dual-output power supply converting a 120-230 V AC (or 88-250 V DC) input into two galvanically isolated, potential-free 15 V DC outputs rated 3.5 A each. Each output is independently adjustable from 12 to 28 V via its own potentiometer, and the unit reaches 88% efficiency at 105 W typical supplied power.
Two independently adjustable 15 V/3.5 A outputs let one PSU3600 unit power two isolated 15 V circuits from a single 120-230 V AC feed, useful where sensor and control loops need separate isolated rails without doubling the supply footprint. Because each output trims 12-28 V independently, this variant fits applications needing a non-standard secondary voltage alongside a second 15 V rail; pick a single-output PSU3600 model instead when both loads can share one common DC bus.
Suited to panels needing two isolated 15 V DC rails from one 120-230 V AC feed — for example separate supplies for an analog sensor loop and a digital control circuit — without mounting two independent power supplies on the DIN rail.
