An apparatus for controlling a variable output of a CT(Current Transformer) voltage is provided to reduce manufacturing costs and parts and improve manufacturing efficiency by using one CT output detection unit. An apparatus for controlling a variable output of a CT voltage includes a CT output detection unit, a variable CT output control unit(700), and a microprocessor(600). The CT voltage output detection unit detects a change of a current inputted through commercial power from the CT, and converts and outputs the change of the detected input current into a voltage. The variable CT output control unit(700) varies a resistance value of the CT output detection unit so that the output voltage outputted from the CT output detection unit is uniformly maintained although one heating coil operates or two heating coils operate at the same time. The microprocessor(600) outputs a control signal for a resistance value variable of the CT output detection unit to the variable CT output control unit(700). |
