Basler SR32A-2B13B3E Static Voltage Regulator

The Basler SR32A-2B13B3E (also designated SR32A2B13B3E) is a solid‑state static voltage regulator designed for medium‑sized brushless synchronous generators. This regulator provides precise automatic voltage regulation (AVR) for generator sets in industrial, marine, and commercial applications, ensuring stable output voltage under varying load conditions.

The regulator features robust construction with advanced protection functions including over‑excitation limiting, V/Hz protection, and loss‑of‑sensing detection. It includes potentiometers for voltage setpoint, stability, and droop adjustment, as well as LED indicators for status monitoring. The SR32A‑2B13B3E is designed for panel mounting with screw terminals for easy connection.
