About Cigarette Lighter and Car Power Supply - Why the Whole Power Supply System is 12V?
Nowadays, there are more and more electrical devices on the car, and the car power system not only supplies electricity to the engine starter motor, lights, electric power steering and other components, but also meets the power requirements of such devices as multimedia audio and video system, reversing radar, cell phone charging, car recorder, GPS navigation device and so on.
The car power system is generally composed of generator and battery together, but not at the beginning of the standard is 12V, as early as the early development of the car, the electrical system was not introduced into the car products, and then around 1918, because of the popularization of the application of the starter, the car began to be equipped with a battery, the voltage standard at that time is 6V. After the 1950s, because the power provided by the 6V system was too low to meet more "power needs", the standard voltage on board was raised from 6V to 12V.
The 12V value then became the global standard (24V for diesel cars), thus significantly reducing coordination problems between vehicle manufacturers and the electrical equipment parts supply chain, and significantly reducing costs. In the 1990s, U.S. auto companies once envisioned upgrading to 42V to cope with future automotive electrification equipment requirements, but the cost of change was too great and all electrical components, including wiring, had to be completely replaced, and eventually could not be promoted in the market.
Of course, set to 12V DC voltage and safety considerations, one can provide the current and power are not large, not easy to trigger a short circuit overheating or fire risk; the second is that even if there is leakage occurs, 12V voltage on the human body will not cause the risk of electric shock.

While there are many factors to consider when designing an overall system, terminal blocks are an optimal solution for complex electrical system connections. With a variety of color options and configurations, Premier Cable’ terminal blocks offer a range of options to meet your design challenges.
CAN-bus has been widely used in various automation control systems. For example, CAN-bus has incomparable advantages in various fields such as automotive electronics, automatic control, smart buildings, power systems, and security monitoring.
M12 encoding types are A encoding, B encoding, D encoding and X encoding. A-code, B-code and X-code are some of the earliest developed and longest-available M12 connectors. The latest M12 coding types currently under development are K coding for AC and L coding for PROFINET DC.
The three different sizes of NMEA 2000 certified DeviceNet standard cabling are "micro," "mid," and "mini."
The Premier Cable Starter Kits provide everything you need to get to create a basic NMEA 2000 network from scratch.
DeviceNet_network is a fieldbus network protocol based on Controller Area Network (CAN). In the DeviceNet network, the terminal resistor plays the role of compensation and protection for signal transmission. The function of the terminal resistor is to eliminate signal reflection and interference and ensure the signal transmission quality.
