In the circuit, the T2, D5, VW1, R5, R6, C10 and K constitute adaptive switching action circuit. When the output is lower than 14V, VW1 stops due to lacking of sufficient breakdown voltage, the circuit has no current, T2 cuts off, K does not pull, the contact K is in the normal position, the input current is AC 14V. Conversely when the output voltage is higher than 14V, VW1 and T2 are conducted, the relay K pulls in, 28V AC is put in the circuit. This ensures that the input voltage and output voltage difference is not greater than 15V, then, the typically value of W317 output current is 2.2A.
