AVR GEN M16FA655A is a high-performance Automatic Voltage Regulator (AVR) used in power generators to maintain stable output voltage and protect electrical equipment from fluctuations. This essential generator spare part automatically controls the excitation system of the alternator to ensure consistent, reliable power output under varying load conditions — a must for industrial, commercial and standby generators.
Where It Is Used
The M16FA655A AVR is commonly installed in:
-
Synchronous alternators and generator sets (single and three-phase)
-
Marelli Motori MJB series generators and similar brushless generator models
-
Industrial power plants and standby gensets where voltage stability is critical
-
Equipment requiring precise voltage control to protect electronics and motors
Key Functions & Features
✔ Automatic voltage regulation — continuously senses and adjusts output voltage for stable performance.
✔ Fits single and three-phase generator systems, compatible with a range of alternator sizes.
✔ Rugged and reliable design — fully insulated and protected for harsh environments with humidity, dust and vibration.
✔ Accurate voltage control with regulation precision typically within ±0.5 % for consistent output.
✔ Built-in protection features including under-frequency and over-excitation limiting, plus internal fuse protection.
✔ Fast response time — typically reacts in one cycle to changes in load or speed.
✔ Compact and easy to install on generator control panels and exciter circuits.
