AVR - Automatic Voltage Regulator DER1
El AVR DER1, una evolución del DSR, es un regulador de voltaje avanzado que incorpora detección automática de fases simples y trifásicas, mayor flexibilidad en el control remoto de voltaje, y una precisión de 0,5% en voltaje estático con arranque suave. Sus conectores integrados facilitan la conexión al generador y a módulos de comunicación, permitiendo la programación y visualización de parámetros a través de un PC u otro dispositivo de supervisión. Diseñado para múltiples tipos de generadores, el DER1 es configurable y guarda sus ajustes en una memoria no volátil para un rendimiento optimizado.
AVR - DER1 is the automatic voltage regulator of the generator: it reads the output voltage and corrects the field excitation so the voltage stays stable as the load changes.
A failing AVR shows up before it dies: voltage dips 5–30 V when a large motor starts, lights flicker, or the control panel reboots. When it fails completely the set delivers only residual voltage or trips on overvoltage.

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.
