What is the role of the high voltage input module power supply?(2)
For the TRIM output pin, the center of the output potentiometer and the center TRIM are all connected to +S, -S in the pin module, and the other two ends are connected to +S, -S respectively. There is no +S, and the -S ends receive the positive and negative outputs of the corresponding main circuit respectively (+S is connected to +Vin, -S is connected to -Vin), and then adjust the potentiometer. The resistance of the potentiometer is generally 5~10kΩ.
At the same time, the design of the high-frequency switching transformer winding in the module switching power supply is also very important. The winding of the high-frequency switching transformer not only affects the copper loss, but also relates to the coupling between the high-frequency switching transformer windings, and also affects the iron loss of the high-frequency switching transformer. Influence, the design and manufacture of high-frequency switching transformers have a great impact on the performance of the module switching power supply
high voltage input customized non-standard Marine boost power supply customized module (factory supply The ADJ output pins are divided into input adjustment and output adjustment. Output trim and output trim. The adjustment method of the TRIM pin is the same. When one end of the potentiometer is connected to the center, the output voltage can only increase the output voltage, and the other end is connected to the ground of the input.
Input protection circuit General customized non-standard Marine boost power supply customized module (factory supply products use built-in filters, which can meet the requirements of general Marine boost power supply applications. If a more demanding power system is required, high voltage input customized non-standard Marine boost power supply customized module (factory supply the input filter network should be added. Either LC or π can be used but care should be taken to choose a smaller inductance and larger capacitance.
