This standard defines physical layer and data link layer specifications of a new power supply and communication technology over a power line from a dc power source to multiple dc loads with the following conditions: - Communication speed is 9600 bps or less. - DC power source is 50 V or less. - DC load consumes more than 10 W and less than 2 kW. - The capacity of one power supply is more than 100 W. - Each receiver has its own physical address (4 b or more). - Each receiver is connected to the… read more transmitter through a pair of power line wires of 1 km or less. - Each receiver is connected to the power line in a multi-drop bus or tree topology. - The transmitter transmits the dc power and the electric signals in the form of electrically changing voltage of the wires through the power line to the receivers and the signals are corresponding to the communication packets that include the control command/data for controlling the dc loads and the target address. - Each receiver supplies the transmitted and voltage-flattened dc power to the dc loads. - Each receiver decodes the control command/data and the address from electric signals on the power line and uses them for the connected dc loads if the address matches. This standard is for dc power line communication technology given the name high power differential signal power line communication (HPDS-PLC). The relationship between this standard and known electromagnetic compatibility (EMC) regulations is also addressed. read less
