Description

Technical Field

[0002] With the continuous development of technology, high-power electronic products are used more and more widely, and most of these electronic products require high-power power supply equipment as their energy source.

In addition, due to the instantaneous large current, the voltage of the -48V power supply will drop, which may affect the normal operation of other single boards. Due to the instantaneous large current, obvious sparking will occur on the connector when the single board is inserted, which will cause electromagnetic interference and corrosion of the connector and other problems.
