。FIG. 1 is a block diagram of one embodiment of the present invention. The power supply main body 2 includes an output voltage control section 4 for receiving input from the external power supply 1 and outputting a specified output voltage 5, and a receiving section 6 for receiving a signal for correcting the output voltage 5. ing. The load device 3 includes a voltage detection section 7 for detecting the voltage output from the power supply main body 2, a correction voltage detection section 8 for determining a correction voltage from the load voltage detected by the voltage detection section 7, and a correction voltage detection section 8 for determining a correction voltage from the load voltage detected by the voltage detection section 7. A transmitter 9 is provided for outputting the correction value determined by the detector 8 as a correction signal 10.
以上の構成において、例えば負荷装置３の補正電圧検出

７で検知され、補正電圧検出部８にて基準値と照合され
る。In the above configuration, for example, the standard value of the load voltage set in the correction voltage detection section 8 of the load device 3 is set to 5. When OOV, the load voltage detected by the voltage detection unit 7 is 4.80
If it is V, the difference of +0.2V is sent to the receiving section 6 via the transmitting section 9 as a correction value. The receiving unit 6 receives the correction value +〇. 2V is transmitted to the output voltage control section 4. Therefore, the output voltage control section increases the previous output voltage 5 to +〇. 2VL is supplied to the load device 3. This value is again detected by the voltage detection section 7 of the load device 3, and compared with the reference value by the correction voltage detection section 8.
