The EA04C Automatic Voltage Regulator (AVR) is a compact, self-excited module designed for brushless generators requiring accurate and reliable voltage regulation. This high-performance AVR supports both low (160–265V) and high (300–550V) AC input ranges, selectable via internal switch, making it adaptable to a wide variety of generator systems operating at either 50 Hz or 60 Hz. Built for performance and protection, the EA04C offers precision regulation within ±1%, ensuring consistent voltage output during varying load conditions. Its maximum DC output is 63V, with a continuous current of 4A and short-duration support up to 7A for 60 seconds. Engineered with internal EMI suppression, over-excitation shutdown, and under-frequency roll-off, this AVR delivers a complete solution for voltage stability and generator safety. Additional features like fused protection and low thermal drift enhance its reliability under continuous operation. With rugged construction to withstand vibration, extreme temperatures (–40 °C to +60 °C), and high humidity (up to 95%, non-condensing), the EA04C is ideal for industrial, commercial, and backup generator applications. This versatile voltage regulator ensures your generator system performs consistently, protecting sensitive loads and enhancing operational efficiency across a range of working conditions.
