Abstract

PURPOSE: To realize a continuous test for the fluctuation of an input power source for a long period of time and in the state approximate to the using state of the power source, by giving the prescribed change to the timing, time and duration of fluctuation of the AC input power source for an information processor.
CONSTITUTION: The delay time is set to the delay counter DC by the microcomputer MC, and then the selection information of the thyristors SR1W4 are given to the input of the register REG. The pulse signal ZPL is produced via the voltage of the terminals 5 and 6 of the power supply transformer, and thus the interruption to the MC and the start of the REG are carried out. The output of the REG turns on either one of the SR1W4 to supply the AC power to the information processor DEV. The MC controls the time of ON/OFF of the SR1W4. Accordingly, the fluctuation timing is decided for the input voltage of the DEV based on the contents set up to the REG and thus the contents of the variation of the voltage duration, the fluctuation time and the DC each.
