2.1 Brief Introduction 
IT7300 Series is a kind of single-phase programmable AC power supply. It can 
analog various normal and abnormal AC inputs, and measure a series of 
important parameters of DUT. IT7300 Series power supply has following 
standard communication interfaces: LAN, USB, GPIB (except IT7321) and 
RS232. With combined features of both desktop and systematic power supplies, 
it can deliver multi-purpose solutions based on design and test requirements.
