AS 540 Automatic Voltage Regulator Replacement AVR for Diesel Generators

The AS540 is a sophisticated, 2-phase sensing, self-excited analogue AVR designed specifically for brushless diesel generators. It is the standard regulation component for the STAMFORD® S0 and S1 range, ensuring your alternator maintains a steady output voltage regardless of load changes.

Key Features

  • Precision Regulation: Maintains voltage accuracy within $\pm$1.0%, protecting sensitive electronics from fluctuations.

  • Enhanced Motor Starting: Supports an optional auxiliary winding to improve motor starting performance and sustain short-circuit currents.

  • Under-Frequency Protection: Features a built-in Under-Frequency Roll-Off (UFRO) circuit with an LED indicator to prevent engine overload during speed drops.

  • Durable Design: Built with high-quality electronic components and a rugged, vibration-resistant casing for long-term reliability in harsh environments.

  • Universal Compatibility: A direct replacement for many Cummins and Stamford parts
