The early power supply capacity of the high-voltage module power supply was usually the dc module power supply container, but now it has been developed from the dc power supply to the communication power supply, from the low-temperature power supply to the high-temperature power supply, from the general power supply to the external power supply, from the common structure to the chip, from the plate to the book and so on. Its upper limit capacity has been expanded to about 4f, the application frequency is up to 30khz, the working temperature grade has reached -55℃-125℃ website quotation, some even as high as 150℃, the additional module power supply voltage has reached 700V. Of course, the more items you choose, the more options you have. How to choose high voltage module power supply to solve the problem of module power supply capacity.

How to choose the high voltage module power capacity

1. To solve the problem of power supply capacity as far as possible, the original model of high-voltage module power supply must be selected.

2. In general, the power capacity of the high-voltage module power solution module has a large error, which will not affect the normal operation of the power supply circuit of the module. Therefore, the module power container with a larger or smaller power capacity can be replaced. However, in the power supply circuit of frequency division module, power supply circuit of calibration module, vibration circuit and loop circuit, the power supply capacity of the module shall conform to the accounting requirements as far as possible. In some filtering networks, the power capacity of the black metal steel module power release module and the power capacity of the module power solution module are also required, and the error should be less than ±0.3-0.5.

3. Pressure requirements must be bare handed and the selected pressure bearing value shall be equal to or greater than the original value.

4. In general, the power supply capacity of non-polar modules is replaced by the power supply capacity of non-polar modules. In case of no solution, the inverse series of two polar modules with twice the capacity can be used to replace it. The method is to connect the positive poles of the power supply capacity of two polar modules (or to connect their two negative poles).

5. When selecting the power supply capacity of the high-voltage module, the high-voltage power supply capacity of the high-temperature module shall be selected for the staff assessment in chengdu. The power supply capacity of the high temperature resistant module is 105℃. When the power supply capacity of the high-temperature module runs at a high working temperature, the normal working time can be guaranteed to be around 2000 hours. When the module power supply capacity is 80℃, at 50℃, the service life can reach 22,000 hours. If the high temperature and high pressure module is used for power supply, the service life of the module can reach 90,000 hours.
