4.10 Polyphase Function
IT7800 series power supply to achieve 6 phase& 12 phase power output through
digital IO interface. Taking the 6 phase power supply as an example, introduces
the application method of polyphase function.
Connecting the IO-4 pin
Connect the IO-4 pins of two IT7800 power supplies. One IT7800 outputs
synchronization signals to the other IT7800. The second power supply runs
synchronously with the frequency and phase of the first power supply to realize
the six-phase output function.The wiring diagram is as follows:
