Abstract
A load control apparatus is connected to a master station through a power line supplied with direct-current power. The load control apparatus is driven by the direct-current power supplied from the power line to communicate with the master station through the power line. The load control apparatus includes a PLC part, first and second branch lines, connected to the power line, an impedance element connected to only the second branch line, a motor connected to only the first branch line, a condenser connected in parallel with the motor, the condenser having a capacitance resonating with an inductance component of the motor and frequency of the communication signal, a control part configured to perform a variety of processes, based on the communication signal received by the communication part communicating with the master station, and a circuit power part connected to the second branch line through the impedance element and configured to supply the PLC part and the control part with the desired power.
