Description
Entry-level AVR (legacy).
Did you know
- The Leroy-Somer R120 Automatic Voltage Regulator is a compact, high-performance unit designed for brushless AC generators. It is an original equipment manufacturer (OEM) part, manufactured in France by Leroy-Somer (Nidec).
- The R120 is positioned as an entry-level analog AVR within Leroy-Somer's range, designed for smaller industrial alternators such as the TAL 40, TAL 42, and TAL 44 series. Other models like the R130 and R180 offer broader compatibility with larger alternators and more advanced features.
- The R120 is chosen for its compact design, reliability, and precise voltage control for brushless generators, ensuring stable power output and protecting sensitive equipment. It features advanced circuitry for instant response to load changes and rapid voltage recovery.
| Model | Technology | Excitation Mode | Rated Excitation Current (Continuous) | Voltage Regulation Accuracy (+/-%) | Under Frequency Protection |
|---|---|---|---|---|---|
| R120 | Analog | SHUNT | 4 A | 1% | Yes (46 Hz for 50 Hz, 56 Hz for 60 Hz) |
| R130 | Analog | Compound | 4 A | 1% | Yes (95% of rated frequency) |
| R150 | Analog | SHUNT | 6 A | 0.8% | Yes (below 46 Hz for 50 Hz, below 56 Hz for 60 Hz) |
| R180 | Analog | AREP, PMG | 6 A | 0.5% | Yes (48.5 Hz/58.5Hz for 50 Hz/60 Hz) |
