Description
About the PSU3600
About the PSU3600
The Siemens 6EP3343-0SA00-0AY0 is a SITOP PSU3600 flexi power supply that converts a 120-230 V AC (or 88-250 V DC) input into a DC output adjustable across 3 to 52 V, rated 10 A / 120 W. The output tracks via potentiometer or a 0-2.5 V analog control signal, and the unit reaches 88% efficiency at 120 W typical supplied power.

Selection Notes
The 3-52 V adjustable range, set either by potentiometer or a 0-2.5 V analog control signal, lets one PSU3600 flexi unit replace fixed-voltage supplies across several projects that each need a different DC rail inside that band. The 0-2.5 V current-monitor output feeds an analog input back to a PLC for load tracking without extra sensing hardware, and the 120 W power limiting (rather than a hard current trip) lets the output current fall as voltage is set higher; pick a fixed-output PSU3600 or PSU6200 model instead when the application only ever needs one specific voltage.
Applications
Suited to OEM panels or test setups that need a field-adjustable DC rail between 3 and 52 V, or where the analog control input lets a PLC set the output voltage programmatically.
