Abstract

PURPOSE:To eliminate the breakdown of a cutoff sequence to another power supply, by producing the power supply output according to the input information supplied previously when the input information is outside the allowance value and accordingly avoiding, temporarily the application of the overvoltage to the load. CONSTITUTION:The digital input information is compared with the prescribed allowance value. When the digital input information is within the allowance value, the information receives an analog conversion to obtain an analog power supply output. In case the input information is outside the allowance value, an analog power supply output is obtained in accordance with the digital input information which is supplied earlier than the first mentioned digital input information. For instance, the input information DATA is fetched into a register 1, and the output of the register 1 is compared with the set value of an allowance value setting circuit 4 through a comparator 3. If the output exceeds the allowance value, the output PALARM is set at a low level. And a register of the next stage keeps the previous data as it is.
