PROBLEM TO BE SOLVED: To provide a DC stabilized power source device that can be downsized connectable to a load at a remote location and necessary to correctly control a load voltage without performing phase compensation.SOLUTION: According to a DC stabilized power source device 21 of one example, the DC stabilized power source device, whose power is supplied from an external DC power source 22 and which is connected to a load 23 having a voltage preliminarily set to a prescribed voltage by wiring, comprises: a switch circuit unit 24 that switches the power to convert the power into a pulse signal whose width is variable; a smoothing circuit unit 28 that smooths an output signal of the switch circuit unit; and an output current detection unit 29 that detects an output current. The DC power source device is configured to control the pulse width of the switch circuit unit so that the voltage in the load is the prescribed voltage, and thus, control the output current. |
