Sudharsan insulations provides 3-phase injection current source. The injection current source are available with salient features like mains isolated sine wave injection current; twin unit design or alternatively modular design single unit; independent phase ammeters with ct range selector switch; single 3-phase variac for balanced 3-phase mains supply source or optional 3 independent single phase variacs for marginally unbalanced mains supply source; 25/ 50/ 100 a per phase on common output terminals with current range selector switch and 200/ 400/ 600 a on individual output busbar. The 3-phase injection current source come with technical specifications like 400-440 v, tpn, 50 hz input; 25/ 50/ 100/ 200/ 400/ 600 a phase output and specific burden.
