Whatever tasks you have to tackle : Sitop Power supplies can handle them !

In industrial applications, 24 V DC is becoming the voltage of choice. Unlike other vendors, Siemens offers a wide range of options to complement its power supplies. In additions to the complete product range of 24 V DC power supplies - from 0.5 A to 40 A, and power supplies in 5 V, 12 V, 15 V and 48 V, Siemens also provides power security equipment :

• Buffer modules for sensitive processes to avoid the loss 24 V DC during short power outages or voltage fluctuations

• DC UPS if the process requires longer hold-up times

• Redundancy modules if the process requires a redundant power supply
configuration

• SITOP select electronic diagnostic modules if the application has multiple load ciruits and a shutdown of the circuit, affected by the short, is required
