Introduction to QGKZD-2 DC dual charging pile control board

DC dual charging options are as follows:

Model: QGKZD-2-JC Note: The power of the two guns is fixed and charged at the same time (equal charging)

Model: QGKZD-2-LC Note: Double gun high-power polling charging

Model: QGKZD-2-AB Note: The power of the two guns is automatically adjusted and charged at the same time
