手段の減電圧監視グループである。The power supply unit 21 receives an AC input, and inputs the secondary voltage obtained through T to the rough DC voltage obtained by the rectifying and smoothing circuit 23 to Q, and the output voltage is digitally set to the DAC 27a in the third means. The output signal of the operational amplifier 24m, which compares and amplifies the error with the reference voltage, is fed back to the base of Q.
The output voltage tDA is controlled so that the error output approaches 0.
It operates as a constant voltage power supply according to the reference voltage by C27. The operational amplifier 24& is controlled by the main control unit 1111.
It has a gate function controlled by the closing signal of the closing circuit 26 of the f42 means that receives the signal, and when the cutting signal is applied, the output is shifted to a low level to suppress the pace of Q and reduce the output voltage t. -O cut off each DAC27a
It is assumed that the above reference voltage value is set in accordance with the input digital signal and is continuously held and transmitted. The portion centered around the yt calculation amplifier 24 b e c is the output current monitoring group of the fourth means. The voltage drop caused by the output current obtained through R1 is converted into an output voltage based on the ground potential by the operational amplifier 24bK, and then inputted to the operational amplifier 24c, and then a digital signal is set to the DAC 27b by the main controller 1. If an overcurrent is detected that causes the output voltage of the operational amplifier 24b to exceed the threshold voltage of the current, the stop control section 1 is notified via the AND circuit 28a. This notification operation is performed by the mask register 2 from the main control unit l.
Depends on the setting of the set signal performed in 9aK. Performance width device 24d
1 minute centered on is the overvoltage monitoring group of the fifth means. In this case, the operational amplifier 24d compares the upper limit threshold voltage of the output voltage based on the digital signal set by the DAC 27cK with the output voltage of the power supply section 22, and the result that the output voltage exceeds the threshold voltage is obtained. Similar to Tatokisha, the overvoltage is notified to the main control unit l via the AND circuit 28b. Next, the central part of the operational amplifier 24e is the 6th
This is a means of reducing voltage monitoring group.

準値とし−〔も同様に実現出来ることはいう迄もない。The operational amplifier 24e compares the lower limit threshold voltage of the output voltage based on the digital signal set to the DAC 27d and the output voltage of the voltage supply section 22, and it is determined that the output voltage is lower than the threshold voltage. notifies the main control unit 1 of the voltage reduction via the AND circuit 28c. Since the present embodiment is configured as described above, the main control section 1 controls output voltage on/off for one or more power supply units 2a-nK, as well as output voltage value, overvoltage, undervoltage, and overcurrent. It is possible to supply a normal voltage current to the load 3 by arbitrarily setting the values for each output, and it is possible to immediately recognize an abnormality in the power supply or load by the notification signal from the power supply unit 2a-n. Therefore, a method for controlling and monitoring the power supply circuit that can efficiently implement countermeasures can be obtained. Not only can the operator be recognized by notification signals, but it can also be easily recognized by 2-lamp lighting, text display, sound/voice, etc. It can be achieved. Furthermore, although the IT power supply unit is based on the top-mounted series dropper system, it can be similarly modified by applying it to a switching system. Sara K
W (can be similarly applied to, for example, a cooling unit, etc., instead of the source unit.Although the threshold values set by the DACs 27a to dK are set to all values for the necessary area, it is also possible to set the center value of the threshold value as a fixed memory. It goes without saying that the angle correction value can be similarly realized by inputting the angle correction value by digital setting, and adding and subtracting it by setting it as a comparison reference value for each operational amplifier 24.
