Siemens 6EP1334-2BA20 SITOP PSU100S 24 V DC/10 A stabilized power supply

Siemens 6EP1334-2BA20 is documented for the stated industrial system role: Converts single-phase AC mains into a regulated 24 V DC, 10 A supply for PLC, I/O, HMI, and other control-panel loads.

System function

Rebuilt from individual evidence

System position

Siemens identifies 6EP1334-2BA20 as a SITOP PSU100S one-phase stabilized power supply with 120/230 V AC input and 24 V DC/10 A output.

Siemens documentation specifies 85-132 V and 170-264 V AC input ranges, 24 V DC output, 10 A rated current, and IP20 protection for the exact reference.

Converts single-phase AC mains into a regulated 24 V DC, 10 A supply for PLC, I/O, HMI, and other control-panel loads.

The system position is an explicit inference from the exact-reference evidence.

Unknown: cabinet load profile, protective-device coordination, wiring, ambient conditions, and installation-specific compliance.

System role

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

Function: Converts single-phase AC mains into a regulated 24 V DC, 10 A supply for PLC, I/O, HMI, and other control-panel loads.
System position: Sits at the head of the automation power chain between AC mains and the 24 V DC control bus.
Upstream / inputs: Receives single-phase AC within the documented 85-132 V or 170-264 V ranges.
Downstream / outputs: Supplies the downstream control bus with regulated 24 V DC at the documented 10 A rating.
Limitations: Unknown: cabinet load profile, protective-device coordination, wiring, ambient conditions, and installation-specific compliance.
