Description
L-series variant of R450.
Did you know
- The Leroy-Somer R450 Automatic Voltage Regulator (AVR) is an analog AVR manufactured in France. While a specific launch year is not consistently available, documentation for the R450 AVR dates back to at least December 2019.
- The R450 is a premium, high-performance analog AVR within the Leroy-Somer (Nidec) range, designed for industrial AC generators and compatible with LSA series alternators. It offers more advanced features and broader excitation system compatibility (SHUNT, AREP, and PMG) compared to simpler models like the R250, which is primarily for shunt-excited systems.
- The R450 is chosen for its precise voltage control, high reliability, and versatility across different excitation systems (SHUNT, AREP, and PMG). It is also suitable for harsh environments due to its robust design and ability to withstand high levels of vibration.
| Model | Excitation System Compatibility | Voltage Regulation | Sensing Input | Load Acceptance Module (LAM) |
|---|---|---|---|---|
| R450-L | SHUNT, AREP, PMG | ±0.5% | 1-Phase or 3-Phase (configurable) | Integrated (active as standard) |
| R250 | SHUNT | ±1.0% | 1-Phase | Integrated |
