Description
Older digital platform (legacy).
Did you know
- Leroy-Somer, now part of Nidec, offers a range of Automatic Voltage Regulators (AVRs) as part of its electronic products for gensets and power production systems. While a specific launch year for the R707 is not readily available, Leroy-Somer AVRs are described as incorporating the latest technology.
- The R707 is an analog Automatic Voltage Regulator within Leroy-Somer's electronic product line. It is part of a series that includes other analog AVRs, as well as more advanced digital voltage regulators like the D350, D550, and D700, which offer higher control and configurability.
- Leroy-Somer AVRs, including the R707, are chosen for their ability to maintain precise output voltage for generators, ensuring stability and protecting sensitive equipment from fluctuations. They are designed to provide reliable voltage stabilization and efficient operation.
| Model | Excitation Type | Key Features | Compatibility (Sibling AVRs) |
|---|---|---|---|
| R707 | Analog | Voltage regulation, compact and encapsulated unit, suitable for brushless generators. | N/A |
| R150 | Analog | Excitation power from main generator output, soft start, frequency roll-off, droop CT connection for parallel operation. | N/A |
| R726 | Analog | Power factor regulation for paralleling with mains, voltage equalization, paralleling with other alternators. | R129, R130, R438, R450 |
| D550 | Digital | Precise voltage output, programmable functions, U/F control, LAM (load acceptance module), parallel operation support, excitation current up to 8A. | N/A |
