(I) Functional features of SP series DC modules:
1) High efficiency, the module efficiency can reach 91%~93%;
2) Light weight, 220V10A, 11OV20A air-cooled modules are only 10kg; self-cooling modules are about 11KG;
3) Small size, depth 396×height 246×width 105mm;                                                          
4) Adopting "three-phase passive power factor correction circuit", the input has no neutral line, 
and the power factor can reach 0.95; 5) Adopting isolated autonomous current sharing, the parallel uneven current degree is <±3%, which can ensure good parallel connection of more than 20 modules;
6) The module has built-in DC output isolation diode, and the user does not need peripherals;
7) The module has RS48/232 communication interface, digital display keyboard operation, friendly human-machine interface, and has functions such as communication, data display, data calibration, average floating charge conversion, overcurrent and fault alarm.
