coil type load voltage sag protection device
产品说明：
the coil type load voltage sag protection device realizes the intelligent control of the ac contactor by dynamically analyzing the parameters of the contactor coil inductance, utilizing the power electronic technology, the single chip control technology, and the ac contactor body to ensure that the grid voltage is reduced. at 25% and above, the contactor remains closed, effectively avoiding the impact on the continuous production when the grid is low voltage.
