Siemens 6ES5930-7AA11 SIMATIC S5-110A PS 930 power supply is documented for the stated industrial system role.

System function

Rebuilt from individual evidence

System position

Siemens SIMATIC S5-110A PS 930 power supply module.

Converts 220 VAC input to 5 VDC at 0.7 A for the S5-110A control system.

The system position is an inference from the documented component function and adjacent interfaces.

Unknown: actual output limit for the installed unit, mains wiring, protection devices, installed condition, and system compatibility.

Exact reference: 6ES5930-7AA11
