Remarks:
1. When the secondary of the transformer is single winding, the maximum capacity in the above table can be selected; when the secondary is double or multi-winding, the capacity is appropriately reduced.
2. The first stage of HDB series is copper wire winding; the first stage of HDBL series is copper wire or copper-clad aluminum, and the second stage is aluminum wire.
