Did you know
- Leroy-Somer, a French company established in 1919, designs and manufactures rotating machinery, including alternators and motors. Nidec acquired Leroy-Somer, and the company continues to produce a wide range of alternators and associated electronic controllers.
- The R430 is part of a series of Automatic Voltage Regulators (AVRs) offered by Leroy-Somer (Nidec), which includes models like the R230, R250, R438, R448, R449, and R450.
- Leroy-Somer AVRs are designed to ensure stable and quality voltage output, protecting generators and connected equipment. They are known for high performance, reliability, and long service life, often featuring functions like U/F control and Load Acceptance Module (LAM) for handling sudden overloads.
