Description
Basic analog AVR for LSA entry models.
Did you know
- The Leroy-Somer R220 Automatic Voltage Regulator (AVR) is a product of Leroy-Somer, a French division of Nidec, a company known for its engineering in generator voltage regulation technology.
- The R220 is an analog AVR designed for small alternators with SHUNT excitation, distinguishing it from models like the R450 and D510C, which are offered for AREP or PMG excitation systems.
- The R220 is chosen for its straightforward design, reliable voltage regulation (±0.5%), and ease of installation and maintenance, particularly in single-phase and select three-phase shunt-excited generator applications.
| Model | Excitation System | Voltage Regulation | Nominal Excitation Current | Max Excitation Current (10s) | Response Time |
|---|---|---|---|---|---|
| R220 | SHUNT | ±0.5% | 3A | 7A | 500ms |
| R230 | SHUNT | ±0.5% | 3A | 8A | 500ms |
