6.11 Synchronization Function

IT8200 series load to achieve 6 phase& 12 phase power input through digital IO
interface. Taking the 6 phase load as an example, introduces the application
method of polyphase function.
Connecting the IO-4 pin
Connect the IO-4 pins of two IT8200 electronic loads. One IT8200 inputs
synchronization signals to the other IT8200. The second load runs
synchronously with the frequency and phase of the first load to realize the six-
phase input function.The wiring diagram is as follows:
