(0 review)
El AVR R230 es un regulador de voltaje analógico con control de potencia por transistores, diseñado para alternadores pequeños con excitación SHUNT. Este AVR es eficaz, fácil de ajustar y fiable, controlando la corriente de excitación para mantener la tensión de salida del alternador. Opera con una entrada monofásica de 85-139 V CA a 50/60 Hz y proporciona una salida máxima de 90 V CC a 207 V CA. Su corriente de salida continua es de 6 A CC, con un máximo intermitente de 10 A CC por 10 segundos, y requiere una resistencia de excitatriz mínima de 15 Ohmios. Para su arranque, necesita un voltaje remanente (BUILD UP) de 4 V CA. Puedes descargar su manual haciendo clic aquí.

AVR - R230 belongs to the generator excitation circuit and holds the output voltage within about ±1 % when the load steps up or down.

AVR wear is thermal. It works inside the generator compartment with no ventilation of its own, so it is usually the first module to age on a high-hour set. Keeping one on the shelf avoids a multi-day stop for a low-cost part.

How to verify before ordering

  • Check that the reference printed on the AVR label (for example AS440, MX341, R120) matches exactly; variants differ in sensing range and excitation level.
  • Confirm the excitation input voltage and the generator type it serves. They are not interchangeable across generator makes or speed ranges.
  • Inspect wiring and brushes before replacing the module: a loose connection produces exactly the same symptoms as a burnt AVR.

Frequently asked questions

How do I know the fault is the AVR and not the generator?

Measure output voltage at steady load. If it is low and does not respond to the excitation trim, while windings and rotating diodes are healthy, the AVR is the suspect. A cross-test with a spare AVR confirms it in minutes.

Can the voltage be trimmed after installation?

Yes. Most of these regulators have a voltage and a stability trim pot. Set them at no load to the site nominal voltage, then verify under load before signing off.
