Hello prataks; If you are speaking of S7-400 CPUs used for PCS 7, you coulduse the Power supply modules chapter from the S7-400 Module Data manual to locate the information you request: http://support.automation.siemens.com/WW/view/en/1117740 You will find specifications for each power module MLFB, such as: Specifications of the PS 407 10A and the PS 407 10A R Input voltage • Rated value 110/230 V DC 20/230 V AC (varying voltage input) Line frequency • Rated value 50/60 Hz • Permissible range 47 to 63 Hz |
