配線をしていた。Conventionally, when supplying voltage from a DC power supply to a load, in order to measure the voltage at the load end, there is a voltage drop due to the cable between the power supply and the load, so it is necessary to connect the load separately from the voltage supply cable. Wiring for a voltage monitor was run from the end to the power supply side.
前述した従来の電圧測定構成では、電圧モニタ用のケー
ブルが電圧供給用のケーブルの本数分だけ必要になる。In the conventional voltage measurement configuration described above, the number of voltage monitor cables is equal to the number of voltage supply cables.
このため、電源一負荷間の距離が長い場合や、多出力の
電源の場合は電源一負荷間の配線が非常に繁雑になる。Therefore, if the distance between the power source and the load is long, or if the power source has multiple outputs, the wiring between the power source and the load becomes extremely complicated.
また、高電圧電源の場合は、電圧供給用のケーブルのみ
でなく、電圧モニタ用のケーブルについても高電圧に対

本発明の目的は、前記欠点が解決され、電圧モ二夕用の
ケーブルを不要とし、負荷とは簡単な配線で済むように
した直流電源装置を提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a DC power supply device which solves the above drawbacks, eliminates the need for voltage monitor cables, and allows simple wiring to be connected to the load.

特徴とする。The present invention provides a DC power supply device that supplies DC voltage from an output terminal of the device main body to both ends of a load via a cable, including means for detecting voltage and current at the output terminal of the device main body, and a means for detecting the voltage and current at the output terminal of the device main body. and means for deriving the voltage across the load from the voltage and current generated by the load.
