PURPOSE:To omit the manual setting of the power supply conditions by setting the voltage conditions by a data processor itself together with execution of a voltage margin test. CONSTITUTION:A power supply device 12 converts the AC power given from an AC power line 1 into the DC power. Then the device 12 sends the DC power to a data processor 11 through a power line 3 and at the same time displays the voltage via a voltage display device 13. While the DC voltage setting signal is sent to the device 12 from the processor 11 through a signal line 2. The processor 11 sends a timer start signal to a signal line 5 at the set voltage level. Then a timer device 14 starts its counting action, and a timer stop signal is sent to a signal line 6. Thus the counting action of the device 14 is stopped. If the timer count value is abnormal, an alarm signal is delivered to the line 6. |
