AS440 AVR: Overview & Technical Details

The AS440 AVR is a high-performance Automatic Voltage Regulator engineered to stabilize generator output voltage by dynamically adjusting excitation current. It compensates for load fluctuations, ensuring consistent voltage levels and protecting sensitive equipment from power irregularities. Ideal for industrial, marine, and backup generator applications, the AS440 combines precision, reliability, and ease of use.

Key Features:

  • Dynamic Voltage Regulation: Compensates for sudden load changes to maintain ±1% voltage stability.

  • Compact & Durable Design: Robust housing for harsh environments (IP54 rating).

  • User-Friendly Interface: Adjustable settings via front-panel dials or remote control.

  • Overload & Short-Circuit Protection: Safeguards generator and connected loads.

  • Wide Compatibility: Suitable for brushless and brushed generators (up to 1500 kVA).
