Product parameters, matters needing attention;


The primary winding is divided into two windings. When the secondary is only one winding, it takes all the rated capacity of the transformer. As with secondary control, lighting and light windings, according to the distribution of winding capacity are respectively wound on the transformer winding and a single tap, the intermediate tap capacity is smaller than transformer's rated capacity, only the highest output voltage can be responsible for the rated capacity.
