A power controlling apparatus with a power failure detecting function
摘要:
A CPU (20) in a power source controller (4) generates various error status data, that correspond to various kinds of failure conditions, based on detection signals supplied from a variety of failure detection circuits (5-7, 10-13) provided at a power source circuit. The CPU (20) controls an LED (14) in a blinker based on the error status data to light up and extinguish the LED (14) in an orderly fashion which is fixed by the generated data, so that the blinker blinks variously in correspondence with various kinds of power failure conditions. Thus, a various kinds of power failure conditions can be indicated by difference in blinking operation of the blinker.
