Who can tell me that the electrical design inside the weak design is how to calculate the weak bridge to it, how to accurately calculate how much capacity should be used in the weak bridge, thank you more
What does the amplifier need for a power supply, what does the power amplifier mean, are you talking about the boost circuit? If it is a signal amplifier, then, is the weak low signal amplification, and power is to provide energy to the amplifier.
National standard wire and cable requirements: the minimum value of the minimum value of the maximum diameter ~ the largest number of core countries have a national model models can also be customized according to customer requirements of different core number of different specifications of the cable other provisions: such as tensile pressure test Coal mine cable national standard is: MT818-2009 power cable is: GB / T-2008 Overall, each cable has its fixed standard, after the specific problem specific analysis of it pure hand, hope to adopt
