AMPLIFIER DEVICE WITH POWER CONSUMPTION MONITORING FUNCTION

摘要

PROBLEM TO BE SOLVED: To display a variation of power consumption during use in real time by providing a power consumption monitoring function in an amplifier device that amplifies an electric signal.SOLUTION: The amplifier device including the power consumption monitoring function includes: an amplifier circuit for amplifying an electric signal; a voltage setting section or a voltage detection section which sets or detects a voltage to be inputted to a power supply circuit for supplying power to the amplifier circuit; a current detection section for detecting an output current of the power supply circuit; an arithmetic processing section for calculating power consumption by calculating the input voltage set by the voltage setting section or the input voltage detected by the voltage detection section and the output current detected by the current detection section; and a display section for displaying the power consumption calculated by the arithmetic processing section.
