Claims

[Claims for Utility Model Registration] , (1) A DC power supply having at least two types of output;
A constant voltage control system includes a comparator that operates as a reference side of the DC power supply and compares the output voltage of one of the DC power supplies as a reference voltage, and controls the output voltage of the one output to a constant voltage using the comparison output of the comparator; A DC power supply device comprising a transistor whose base is connected to the output of a comparator with an emitter-collector interposed between the other output and the output terminal. (2) Utility Model Registration Scope of Claim 1. The DC power supply device according to claim 1, wherein the foot voltage control system is a constant voltage circuit of a series control type. (3) The DC power supply device according to claim 1, wherein the constant voltage circuit 11 is a constant voltage circuit of a switching control type.
