The Siemens SITOP PSU6200 6EP3323-7SB00-0AX0 is a stabilized 12 V DC power supply delivering 7 A (84 W) from a 120-240 V AC or 120-240 V DC input, with push-in terminals and 87.1% typical efficiency. Output overshoot on switch-on stays below 2%, and the unit has a 29 A inrush current limit and a signal contact for DC-OK monitoring.
The PSU6200's push-in terminals and 99-275 V DC input rating, in addition to 120-240 V AC, let it run directly from a DC bus or UPS without a separate rectifier, unlike the screw-terminal LOGO!Power line. At 7 A/84 W, with up to 100 W available below 45 degrees C, it is sized for a small-to-medium 12 V control-cabinet load; step up to a higher-current PSU6200 variant if the load regularly approaches the 8.4 A short-term overload ceiling rather than only at start-up. The redundancy module listed as a compatible accessory allows two units to be paralleled for supply redundancy.
12 V DC control cabinet power for PLC peripherals and sensors, DC-bus-fed installations, and panel builds requiring push-in wiring.
