Генератор E1X13S A/4

The E1X13S A/4 is a 4-pole, three-phase brushless synchronous alternator designed for small to mid-range generator sets. Featuring a self-excited AVR-controlled system (models HVR11 or HVR30), it maintains voltage stability within ±1% across variable loads. Its total harmonic distortion (THD) remains below 3%, guaranteeing clean and stable electricity for sensitive equipment.
