5.8 Full 4-Quadrant Power Amplifier 
The IT7900P series regenerative grid simulator can be used as a power amplifier 
to  complete  power  hardware  in  the  loop  (PHIL)  applications  for  microgrids, 
energy storage and new energy vehicles. The digital I/O or a standard suite of 
analog    signal can be input via an external analog interface (optional) and then 
amplified without distortion to a real power waveshape. 
The  power  amplification  function  can  only  be  realized  by  selecting  external 
analog interface. Please refer to the Analogue function in 6.14 for the specific 
use method. 
5.9 Auto-range Function 
IT7900P  series  power  supply  can  achieve  the  combined  output  of  multiple 
voltage and current at  a fixed power. Single power supply  can  meet  different 
DUT tests with high voltage low current or high current low voltage, at the same 
time, because the output of voltage and current is controlled by the limit power, 
it  will  show  the  switching  of  voltage  and  current  auto  ranging.  To  avoid 
Intermittent output shutdown when switching the high range and low range.
