The high frequency of LED switching power supply is its development direction. The high frequency makes the switching power supply miniaturized and enables the switching power supply to enter a wider range of applications. led switching power supply ,So what should be paid attention to when choosing and using LED switching power supply?
1. The led switching power supply has a resistive load before leaving the factory. For capacitive or inductive loads, please specify in advance when ordering.
2. Sink and leakage current: When multiple power supplies are used, they share a ground point. The total leakage current is formed by the sum of the leakage currents of each cell. At this time, the reliability of the protective grounding wire should be checked and whether the grounding resistance meets the requirements to avoid electric shock.
3. In order to achieve the effect of sufficient heat dissipation, it is generally installed in a position with better air convection conditions or on the casing of the chassis, and the heat is dissipated through the casing.
