Question asked by Husain_Jawad on Apr 4, 2017


I want to ask about the resistors for current transformers R1 and R2, is there any fixed resistance? and if there is not and i want to use a CT its 5A/1V its output is a 1 volt, what to do?


also i want to ask about JP8A, JP8B, and JP8C, are these jumpers soldered and fixed to work as a 3 phase? and if not should i solder them before i use the board? and another question if i want to use the board on a single phase (phase A) what should i do?
