Description
Mid-range analog.
Did you know
- The Leroy-Somer R250 Automatic Voltage Regulator (AVR) was introduced in July 2007 as an improvement and replacement for the earlier R230 model.
- The R250 is positioned as an analog AVR designed for small to medium alternators with SHUNT excitation, sitting below more advanced models like the R450 which supports SHUNT, AREP, or PMG excitation systems and offers optional three-phase sensing.
- The R250 is chosen for its reliable voltage regulation, straightforward setup, ease of use, and dependable performance, particularly for alternators utilizing SHUNT excitation.
| Model | Voltage Regulation | Nominal Excitation Current | Max Excitation Current (10s) | Supply/Sensing Range | Excitation System |
|---|---|---|---|---|---|
| R250 | ± 0.5 % | 5A | 7A | 85 to 139 V (50/60Hz) | SHUNT |
| R230 | ± 0.5 % | 8A (continuous) | 10A | 85 to 139 V (50/60Hz) | SHUNT |
| R450 | ± 0.5 % | 6A | 10A | 150V (50/60Hz) / ≤ 530V sensing | SHUNT, AREP, PMG |
