Compact Power Security with Siemens SITOP Power Supplies
 
Modern automation technology is becoming more and more demanding, incorporating electronics that are increasingly sophisticated and sensitive. Therefore, a reliable power supply is the prerequisite for safe efficient operations. For over a decade, Siemens has engineered SITOP power supplies to be the best solutions – in terms of reliability, sturdiness and expandability with over five million units sold.
New Power Security Options:    
Signaling Module
Monitors the input and output voltage status of the power supply from the higher level control system. Provides remote power supply on/off switching capability from higher level control systems such as PLCs.

 
     
Redundancy Module
Builds a redundant power supply by decoupling 2 power supplies set up in parallel connection. In case the output voltage of one power supply drops below the selected threshold voltage the redundancy module makes sure that the standby power supply takes over immediately. An auxiliary contact provides status information of the redundant power supply to the upper level control system.
 
     
Buffer Module
Protects against brownouts and short voltage fluctuations by maintaining the selected DC output voltage within 1 VDC from 100 ms up to several seconds. Green LED indicates that the supply voltage is > 20.5 VDC.

 
     
DC UPS and Battery
Builds a DC UPS by adding a DC UPS module and a battery to the power supply. In case the output voltage of the power supply drops below the selected threshold voltage the DC UPS module switches without interruption to battery operation and maintains the preferred DC output voltage for a selected period of time. Relay contacts or an optional serial/ USB interface allow communication with higher level
 
     
Diagnosis Module
Isolates and identifies faulty 24 VDC load circuits on any switched mode power supply. Auxiliary contact provides status information to the upper level control system
