How to ensure the normal work of Car DVR, voltage and current stability is very important, but on the other hand, the input power equipment is fixed, by W=U*I shows that when the voltage change current also changes the direction of change with voltage current is always the opposite.So if the starting voltage is lower, the relative starting current will increase.
The macro is so simple, but can do this stable function and ensure the normal operation of the equipment, it takes a lot of effort, the first is the design of protection circuit, power supply board to know the Car DVR within 1 hours to withstand the impact of hundreds of times, the protection circuit is not good, light power plate is damaged, while direct breakdown power board motherboard burned.

In fact, it is how to protect the hard disk. Because the current hard disk are mechanical shaft disk read-write head and disk distance of only a few microns, if the naked eye, the read-write head is attached to the disk, but even if you do not understand the hard disk you should understand, 5400 RPM hard drive to rotate at least 90 times per second, if the read / write head is attached to the top, with long, the read-write head is not grinding.
So close, if the earthquake is not done well, as long as the head of a little bit of fibrillation, ranging from hard disk, while the read-write head crash (hard disk terminology). So hardware seismic resistance is very important. For more information, please click Vechile video recorder wholesales china.
