Physical layer and data link layer specifications for power supply and communication over power lines from a dc power source to multiple dc loads are specified. Each receiver has its own physical address and is connected to the transmitter through a pair of power lines in a multidrop bus or tree topology. The dc power is sent by the transmitter. This dc power, by electrically changing the voltage of the wires, corresponds to the communication packets, including the control command/data for controlling the dc loads and the target address. Power to the dc loads with the transmitted and voltage-flattened dc power is supplied by each receiver. The control comman...

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 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 ...

The purpose of this standard is to define how to supply power and transmit a control command or data through a power line to the dc loads in an economical and reliable way, such as: - Light-emitting diode (LED) lighting - DC motor - DC actuator - Battery control device - DC home electronic appliances from dc power source, such as alternating current (ac) to dc power conversion device - Battery - Uninterruptible power supply (UPS) - Energy storage system (ESS) - Renewable dc power generation device, such as a solar panel This standard provides the following advantages: - It enables high noise margin and signal-to-noise (S/N) ratio as well as common mode noise...
