What is the role of the high voltage input module power supply?(2)


power module

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.

(1) After opening the package, it is necessary to carefully check whether the identification of each terminal is in line with the instructions that are brought along with it, and whether it is in line with the requirements of the order contract. If it does not match, you should immediately contact the production or sales unit to discuss how to deal with it.
(2) As the first step of installation, the metal casing of the module power supply must be grounded reliably to ensure safety, but the casing should not be connected to the zero line by mistake.

high voltage input dc Marine boost/buck voltage power supply module 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 dc Marine boost/buck voltage power supply module supply products use built-in filters, which can meet the requirements of general Marine boost/buck voltage power supply applications. If a more demanding power system is required, high voltage input dc Marine boost/buck voltage power supply module 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.
