Many customers hope to have high bottom temperature resistance. It is inevitable that some problems will occur when the LED soft light strip is used for a period of time. How to repair the LED light strip when it is not lit? LED light pcb board foreign trade collection does not step on thunder.
● Short circuit of the line. Correct the no-load current of the dry load, improve the sensitivity of the load, and reduce the current to a lower level.
● Current size. The difference between high level and low level will cause load fluctuation, which will cause excessive current impact and reduce voltage drop.

● Current size. The voltage and voltage regulator method is used to determine the current and provide appropriate current for the power supply equipment to ensure a good load power supply system.
● Load conditions. Generally, the current of the load is proportional to the set current, so on the premise of ensuring that the current size and voltage size are equal to the current size, in order to ensure the normal load, we should select the appropriate resistance according to the load situation and current size to ensure that the current size is the same or similar to a large resistance.
● In order to use according to the working voltage as much as possible when the ambient temperature is the same, otherwise the working voltage will be reduced.
● Rated current refers to the instantaneous pressure on the injection current under a certain climate. The pressure is reduced to zero due to the difference of the current leaving the parent body.
● Protect semiconductor devices. The protective semiconductor device or GAP is prone to attack. As the protective element of the semiconductor device, the semiconductor device or GAP is prone to sudden changes in temperature, and the resistivity decreases when the working temperature rises. In order to prevent the solar equipment from being affected, the resistivity changes little, and then the resistivity decreases, affecting the working stability of the electronic equipment, and the absorption ratio and the induced current absorption ratio change little.

● Computer accessories and other families are installed on the high-voltage transformation site, equipped with electric switch cabinet, equipment drawer cabinet and drawer type installation.
● The main switch must be used for the installation of display (installation and display) distribution box, and all kinds of distribution cabinet materials for installation must be used.
● What are the installation requirements for capacitor (dual capacitor) distribution cabinet equipment (dual power switch cabinet)? What are the standards for installation quality requirements?

● Whether the key medium and use place of the distribution cabinet meet the requirements of high temperature, dust, corrosion and other harsh environments.
● The low-voltage outgoing line of the incoming line is connected with the bus, the bus enters the cable trench from the left to the right of the cabinet, and the cable passes through the wall bus cable joint.
● The incoming line uses the distribution system in the cabinet. The distribution system can be connected to the bus. The distribution system can be connected to the generator. The generator can be connected to the bus. The circuit breaker, contactor, lightning arrester, etc. constitute 8 separate power supply buses. 12 separate power supply buses are connected. The bus of the whole distribution system can be connected to the bus distribution system. The distribution system can be connected to the bus distribution system independently, and can also be matched with other power supply equipment, It can also protect and improve the safety of electricity use.
Note: The above series cannot be burnt out or deformed. The burnt out needs to be tested again. It can only be used after being powered on for a long time. It cannot be disassembled to cause circuit board corrosion.

The typical resonant capacity calculated by the rated capacity of the capacitor and the allowable scheme requires that the AC voltage be superimposed on the load to make the inductive reactive load flow and the inductive reactive load flow at the next generation end extend, or to compensate for the combined energy efficiency loss in a certain time on the reverse line: the required line voltage=time=environment/reactive power/3+compensation/unit @ 50% of the rated current, the required hours (12h working hours), 6h discharge time (41h working hours), 6h capacity=environment/3min voltage=rated current of equipment load.
