Description
Legacy digital AVR (service).
Did you know
- Leroy-Somer has been a manufacturer of industrial motors, alternators, and related electronic controllers since 1919. Nidec Corporation acquired Leroy-Somer and Control Techniques in January 2017, expanding its motor, drive, and electric power generation offerings.
- The R829 is a digital automatic voltage regulator, offering advanced regulation features for demanding power generation applications. This positions it as a more advanced option compared to Leroy-Somer's analog AVRs like the R250, R438, and R450, which are designed for reliable excitation and regulation in Shunt, AREP, or PMG alternators.
- The R829 is chosen for its advanced regulation capabilities, including power factor (PF) and kVAr regulation, manual mode, and mains PF regulation. It also incorporates sophisticated functions like the Load Acceptance Module (LAM) and voltage droop, which are crucial for optimizing load management and parallel operation between gensets.
| Model | Technology | Excitation Types | Nominal Excitation Current | Voltage Regulation Accuracy | Parallel Operation |
|---|---|---|---|---|---|
| R829 | Digital | PF, kVAr, Manual, Mains PF | N/A (advanced digital control) | High (precise digital control) | Yes (with advanced functions) |
| R450 | Analog | SHUNT, AREP, PMG | 6A | ± 0.5% | Yes |
| R438 | Analog | AREP, PMG | 5A | ± 0.5% (±1% in some documentation) | Yes (with current sensing option) |
| R250 | Analog | SHUNT | 5A | N/A (basic model) | Yes (with LAM) |
