What is the role of the the 110 v input power supply?(2)

The loss of high-power module switching power supply mainly includes four parts: high-frequency switching loss, high-frequency transformer loss, rectification loss and line conduction loss. In the application of low voltage and high current output, the rectification loss and line conduction loss account for a larger proportion. .

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.

the 110 v input Marine boost power 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 DCDC conversion module Marine boost power supply 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, the 110 v input Marine boost power 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.
