4. AC/DC Power Supply Board
The AC/DC power supply board converts 85 to 260 volts AC, at 50 to 400 Hz, to
30 volts isolated DC. The supply contains its own EMI filter and provides a
regulated output. The supply uses a flyback topology, and is capable of 35 watts
continuous power. The supply is used to charge the battery and to provide DC
power to run the system electronics.
