PROBLEM TO BE SOLVED: To provide DC power source equipment supplying a stable DC voltage to a load at all times, by installing load voltage compensating equipment having voltage control function in the output part of a charger board, detecting a bus voltage of a distribution board installed in the downstream side, and automatically controlling an output voltage. SOLUTION: This DC power supply equipment 1 consists of a charger board which converts AC power to DC power, supplies it to a load through a switching board, and charges a battery. In this case, load voltage compensating equipment 4 having voltage control function which performs floating charge of a battery 6 and is interposed in the output part of the charger board 5 in the downstream side of the battery 6, and a voltage monitoring control means 13 which detects a voltage of an upper rank bus 10 of an upper rank distribution board 8 as a switching board, and outputs a voltage control signal 14 for maintaining an upper rank distribution board bus voltage signal 12 to be in a specified voltage range to load voltage compensating equipment 4 having voltage control function are installed. |
