ELECTRICAL EQUIPMENT
Document Type and Number:
Japanese Patent JP2016059387
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To switch electrical equipment for which a plurality of different voltages of commercial power supply can be used to an optimum drive state in response to the voltage.SOLUTION: Electrical equipment includes: a rectification circuit for rectifying a commercial power supply voltage; a microcomputer incorporating an A/D conversion part having an input port into which a voltage obtained by dividing an output voltage of the rectification circuit is input, and an output port for outputting an output signal for driving a direct current load that converts the voltage input into the input port to a digital signal, and a control part for determining the voltage of the commercial power supply from the output of the A/D conversion part and generating a drive signal for the optimum control of the direct current load in response to the voltage; and a drive circuit part for driving the direct current load by the drive signal output from the microcomputer.SELECTED DRAWING: Figure 1
