AVR Fitment Guide
Reference model: R220
Applicable machine / alternator: Commonly used in Leroy-Somer-style brushless alternator control systems; confirm the alternator series, excitation option and connector assignment.
Regulator for brushless alternator applications. Check self-excited versus PMG supply, sensing voltage, field current, UFRO/frequency setting, terminals and mounting pattern.
Information required for compatibility confirmation
- Generator or alternator brand, full model and serial plate photo
- Clear front/back photos of the original AVR and every terminal label
- Rated voltage, phase and frequency (50/60 Hz)
- Excitation type, sensing voltage and field output/current
- Mounting dimensions, connector style and wiring diagram
Important: Do not select an AVR only by appearance or model text. Terminal assignment, sensing range, field rating, polarity and excitation method must match. Send the above information and we will verify fitment before quotation.
