Profitec S N1

The rectifier Profitec S N1  from AEG Power Solutions ensures the continuous availability of all global requirements in nuclear power plants, power generation, oil & gas, transportation and other heavy-duty industries. With more than 50 years of experience in nuclear power technologies and with customers around the world, AEG Power Solutions is a truly global player and one of the premium suppliers of equipment for nuclear and fossil power generation.


The Profitec S N1 is a 100% analog rectifier. All regulation and monitoring PCBs (built up in SMD method) contain no software and no programmable components or devices. The invention of a 100 % software-free rectifier is due to the DC power supply security and new requirements for safety and qualification processes.


Conformity to grid norms; Unit operation in line with grid operation goals


A robust design crafted for harsh environments and high requirements

Main Features
Overvoltage limiter (Forsmark Event)

In case of input voltage variation, independent of the input voltage gradient, the duration and its maximum value, the patented overvoltage limiter reduces the value of the DC output voltage to less than 115 % of the nominal DC voltage. The overvoltage detection is a self-acknowledging fault.
