Siemens 6EP1336-2BA10 SITOP PSU100S 20 A supply

Siemens 6EP1336-2BA10 is a SITOP PSU100S supply that converts automatic-range AC input to isolated 24 V DC at 20 A.

System function

Rebuilt from individual evidence

Evidence and limits

6EP1336-2BA10 is a Siemens SITOP PSU100S supply with automatic 120/230 V AC range selection and a controlled isolated 24 V DC output at 20 A.

Its system position is the AC-to-DC conversion point feeding cabinet control distribution; the output can be adjusted from 24 V to 28 V through the documented potentiometer.

The Siemens sheet specifies up to 480 W output.

Unknown: the installed cabinet load, wiring, ambient conditions, service status, and replacement compatibility.

System role

This section explains what the product does and where it acts in the surrounding system.

Function: Converts single-phase AC input into a controlled isolated 24 V DC output rated at 20 A.
System position: Sits between the single-phase AC source and the cabinet 24 V DC distribution path.
Upstream / inputs: The automatic-range AC input receives the incoming single-phase supply.
Downstream / outputs: The isolated 24 V DC output feeds downstream cabinet control loads.
Limitations: Unknown: the installed cabinet load, wiring, ambient conditions, service status, and replacement compatibility.
