An apparatus for supplying power to loads for railway signals comprises: a first power module which receives first input power from a first power source, and outputs a first output voltage to a bus; and a second power module which receives second input power from a second power source, and outputs a second output voltage to the bus. The first input power and the second input power may be three-phase alternating current (AC) voltages, and the first output voltage and the second output voltage may be direct current (DC) voltages.

    철도 신호용 부하들에 전력을 공급하기 위한 장치는, 제1 전원(power source)으로부터 제1 입력 전력을 수신하고, 모선(bus)에 제1 출력 전압을 출력하는 제1 전력 모듈, 및 제2 전원으로부터 제2 입력 전력을 수신하고, 모선에 제2 출력 전압을 출력하는 제2 전력 모듈을 포함할 수 있고, 제1 입력 전력 및 제2 입력 전력은, 3상 AC(alternating current)전압일 수 있고, 제1 출력 전압 및 제2 출력 전압은, DC(direct current) 전압일 수 있다.
