Model:PU3009B Power:4VA
Characteristics: Connection: (carefully read before use)
Flat type transformer is designed as double-coil configuration, standard
type with double-way input and double-way output, the same transformer can
obtain different combinations of two kinds of 220V or 110V input voltage and
different voltage by changing connection of input and output coils.
Input: for 220V power voltage: pin 3 and 7 short, pin 1 and 5 input 220V.
for 110V power voltage: pin 1, 7 and 3, 5 short, then pin 1 and 5 input 110V.
Output: For single-way: pin 12 and 16 short, pin 10 and 14 output with
two times voltage and one time current.
pin 12, 14 and 10, 16 short, pin 10 and 12 output with one time voltage and two times current.
For double-way: pin 10, 12 and pin 14, 16 each output with one time voltage and one time current.
