PURPOSE:To realize economically the feed of a constant current to a terminal equipment, by using a multi-output constant current converter. CONSTITUTION:In a multi-output constant current converter 61, switching elements 73 and 74 are turned on and off alternately by signals from driving signal input terminals 71 and 72 to generate square wave voltages at both ends of a transformer 78. Saturable reactors 79 and 80 are used under the forced magnetization condition by these square wave voltages to control a constant current, and the constant current is fed to terminal equipments 31 and 32 after rectification and smoothing in output circuits 83 and 84.
