The voltage regulator board is a sealed electronic device that stabilizes the output voltage of a brushless generator by adjusting the excitation current. Designed for brushless generators with ultra-low magnetizing voltage, it provides a fast response and a more stable output, and is suitable for 220/440 VAC brushless generators with programmable input. The main regulation loop uses an industrial high-stability component, achieving a temperature drift of less than 0.05% per degree Celsius for reliable, steady regulation. The board includes multiple independent protection circuits, delivering safe, convenient, and practical operation.
