    Main features

    The high-quality oxidation treated aluminum material shell has a circular design, convenient installation,and small duty cycle.
    The unique design ensures that the product can adapt to high ambient temperatures and places with significant system voltage fluctuations.
    Install discharge resistor and safety device inside. When the intermal pressure of the capacitor increases or a malfunction occurs, the safety device can automatically disconnect it from the power supply to prevent accidents from expanding.
