Profitec S N1

1/2

The profitec S N1 (rectifier) from AEG Power Solutions ensure the continuous availability of all global requirements in nuclear power plan, power generation, oil & gas, transportation and other heavy industries. With more than 50 years of experience in nuclear power technologies and with customers around the world, AEG PS is a truly global player and one of the premier 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 % free-of-software rectifier is due to the security of DC power supply and new requirements for safety and qualification processes.
