MAEX: Modular Analog Excitation System

Emergency power supplies in power plants must be equipped or retrofitted with modern brushless systems to avoid plant shutdown due to unavailability of emergency power supply. It is very difficult to qualify software-based systems for this application and also very elaborately to integrate these new systems into existing infrastructure, especially with limited space, time,  budget and plant-specific interface conditions.

The Modular Analogous Excitation System (MAEX) provides a software-free dynamic excitation for a wide range of brushless generators.
 Flexible and customized design is guaranteed by smart configuration of standard add-ons such as converters for different voltage supply. A qualified team of engineers brings a wide range of experienced skills into the solution.
