PRODUCT DESCRIPTION
6ES5955-7NC12 Central Rack DC Power Supply
Siemens 6ES5955-7NC12 is the SIMATIC S5 PS955 power supply identified for the ZG 155H central rack. It supplies the documented low-voltage rack power from a 24 V DC input.
The manufacturer spare description specifies a 5 V, 14 A output. The supply is fitted as a rack component within the compatible S5-155H arrangement; electrical connection, system loading and hardware execution must match the installed rack. The exact NC12 designation is retained rather than substituting parameters from an NC11 supply.
