This chapter introduces the front panel, the rear panel, key functions and LCD 
display function of the IT7900P series power supply, make sure that you can 
quickly  know  the  appearance,  instruction  and  the  key  function  before  you 
operate the power supply. Help you make better use of this series of power 
supply. 
1.1 Brief Introduction 
ITECH IT7900P series represents a new generation of programmable, full power 
source  and  sink  4-Quadrant  grid  simulators  and  also  can  perform  as  a  4-
Quadrant power amplifier, providing the flexibility to test widest range of grid-tied 
devices, including PCS, energy storage systems, micro grids, BOBC (V2X) and 
power-related hardware in the loop emulation (PHiL). 
The IT7900P  series  is equipped with  a professional anti-islanding test  mode, 
allowing the user to set R, L, C and active and reactive power parameters to 
simulate  non-linear  loads  on  the  grid  and  achieve    anti-  islanding  testing 
requirement.  The  IT7900P  series  supports  energy  recovery  function  that 
provides  100% current  absorption  and  feeds  back  into  local grid  through  the 
device, saving electricity bills and heat dissipation costs. 
ITECH IT7900P Regenerative Grid Simulator adopts high power density design 
of 15kVA in 3U enclosure and provides wide voltage ranges up to 350V L-N. 
Easily expandable by Master-slave parallel configuration for higher power up to 
960kVA.  Comprehensive  options  of  operating  modes  can  meet  users' 
requirements for single-phase, three-phase, reversed-phase and multi-channel 
testing  requirements.  Extended  AC  voltage  range  to  700V  L-N  enabled  by 
reversed mode. The powerful arbitrary waveform editing function can simulate 
a variety of grid disturbance waveforms, which is an ideal solution for testing and 
R&D laboratories.
