R250 Automatic Voltage Regulator (AVR) | Part No. AEM110RE019

Restore steady power regulation to your industrial alternator with the R250 AVR. Engineered for smaller, compact alternators utilizing a SHUNT excitation system, this analog transistorized module actively manages the excitation current to maintain a rock-solid output voltage regardless of shifting load variations. Precision Voltage Accuracy: Delivers tight, reliable regulation within $\pm 0.5\%$ to defend sensitive equipment from voltage drift. Load Acceptance Module (LAM): Integrated LAM technology automatically buffers transient voltage drops during sudden heavy loads, minimizing engine bogging and maximizing speed recovery. Alternator Frames: Fits Leroy Somer LSA 44.2, 44.3, 46.2, 46.3, 47.2, and TAL series alternators. Major Fleet Integrations: The factory standard regulator used across FG Wilson, Caterpillar, Olympian, and SDMO diesel generator sets.
