What is the difference between an ordinary power cable for a dedicated cable?
Inverter special cable General power cable difference shielding requirements higher, the number of cores is generally 3 +. three lines of the ground line of three symmetrical and phase line intersection. Variable-frequency (VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment. The inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on. The inverter will adjust the voltage and frequency of the output power by the breaking of the internal IGBT, according to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition, the inverter has a lot of protection , Such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, the inverter has also been a very wide range of applications.
Look at the computer and television, respectively, what interface are generally computer and television are more VGA, followed by HDMI, the new out there will be DisplayPort connection at both ends of the wire type is also very rich, VGA-VGA, HDMI-HDMI, etc. also Adapter cable, such as DVI to VGA and one according to the computer and television interface to select the wire, hard link established, win7 will automatically identify, I use the flagship version, feel better than XP. You can choose to clone the screen or expand the desktop and other operations, computer monitors Internet TV while watching movies, like.
Another example is the flashlight and electric shaver although the voltage is very low, power and current is very small, is still strong
