Power Supply Portfolio Extended to Include Redundancy Modules for Small Performance Ranges
Share:
Nuremberg, Germany. Two new redundancy modules, the Sitop PSE202U 24 V / 5 A and Sitop PSE202U NEC class 2 for small performance ranges, have now been added to the Siemens Industry Automation Division power supply portfolio.
The new modules, Sitop PSE202U 24 V / 5 A and Sitop PSE202U NEC class 2, provide greater reliability for 24 volt supplies to loads in the lower performance range. If one power supply should fail, a redundancy module disconnects the defective unit from the working power pack, guaranteeing continuation of an uninterrupted 24 volt supply. A floating relay contact and an LED indicate the failure of one power supply source.
The Sitop PSE202U 24 V / 5 A redundancy module disconnects two power supplies with an output current of up to a five amperes. To safeguard current levels up to 10 amperes, a redundancy module is connected downstream from each power supply. For applications involving a higher power requirement, the tried and tested 24 V / 20 A redundancy module is available.
The second module, PSE202U NEC class2, not only disconnects the power supplies but also limits the output power to 100 VA. Used in combination with Sitop power supplies, which are certified to the UL60950 safety standard, outputs can be implemented which comply with NEC class 2. Where several 24 volt circuits have to be supplied, this means that a
single central power supply is sufficient.
Typical applications for the Sitop PSE202U NEC class 2 redundancy module include the automotive, semiconductor and food industries. With an overall width of just 30 mm, the
compact Sitop add-on modules take up a minimum of DIN rail space. Both modules
are suitable for a temperature range of between -20°C and +70°C, allowing their
use in the toughest of environments.
