Introduction 
IT7320 series sets up the new standard for high performance AC power source.It equips 
with all powerful features such as power line disturbance (PLD) simulation, Dimmer and 
comprehensive measurement functions.With a compact and standard size of 2U.IT7320 
series has built-in LAN/RS232/USB/GPIB communication interface (except IT7321, IT7321 
is equipped with LAN/RS232/USB communication interface).These features make the 
IT7320 series ideal for commercial,power electronics and military test applications from 
bench-top testing to mass production.
