The Problem

Harness in white goods products is expensive, unreliable and hard to maintain.

The Solution

Architecture consisting of Yamar's DC-BUS devices communicating over the 24V DC wires  starching between white goods internal modules, save many control wires and increase products reliability. The DC-BUS semiconductors transfer commands to activate loads and read sensors over the power lines.

Air-conditioner network over power line

Air-conditioner has external unit feeding one or more in house units.

AC power line and a twisted pair data cable electrically connect between these units.

Using the DC-BUS over the AC power line eliminates the need of dedicated data lines. It simplify the installation and eliminate many o the communication errors generated due to environment noise.
