Description
Very small AVR (miniature gensets).
Did you know
- The Leroy-Somer R180 is a fully solid-state automatic voltage regulator (AVR) designed for the excitation of brushless alternators. It is compatible with alternators powered by a Permanent-Magnet (PMG) exciter or by auxiliary windings.
- The R180 is part of a series of analog AVRs from Leroy-Somer, including models like the R120, R150, R250, and R450. It offers a higher rated excitation current compared to the R120 and R250, but less than the R450.
- The R180 is chosen for its reliable voltage regulation, providing excitation current up to 6A for permanent magnet (PMG) or AREP excitation types. It includes advanced protections such as over-excitation limitation and voltage sensing loss, and features voltage droop for genset parallel operation.
| Model | Excitation Type | Rated Excitation Current (A) | Voltage Droop for Parallel Operation |
|---|---|---|---|
| R180 | AREP, PMG | 6 | Yes |
| R120 | Shunt | 4 (continuous) | Yes |
| R250 | Shunt | 5 | No |
| R450 | Shunt, PMG, AREP | 6 | Yes |
