Description
The Leroy-Somer EM10 is a specialized excitation interface module designed to work alongside Leroy-Somer Automatic Voltage Regulators. It is primarily used to manage and optimize the power supply from AREP (Auxiliary Winding) or PMG (Permanent Magnet Generator) systems to the main AVR.
By providing an isolated and stable power feed, the EM10 ensures that the generator excitation system can maintain a high short-circuit current (typically 300% for 10 seconds). This makes it a critical component for industrial generators that face heavy motor-starting loads or require high reliability in harsh electrical environments with significant harmonic distortion.
