The AVR Stamford R250 is a high‑performance Automatic Voltage Regulator (AVR) designed to maintain stable and consistent voltage output in diesel generator alternators, especially Stamford and Leroy Somer types. By automatically adjusting excitation to the generator’s rotor, it prevents voltage fluctuations that can damage electrical equipment, ensuring reliable power output for industrial, commercial and residential applications.
Where It Is Used
The R250 AVR is widely used in:
-
Diesel generator sets with Stamford or Leroy Somer alternators
-
Backup power systems for telecoms, hospitals and offices
-
Construction and industrial generators
-
Marine and agricultural power applications
-
Any alternator requiring precision voltage regulation under varying loads
