What is the role of the vehicle module power supply?(1)

For custom-make products with TRIM or ADJ (adjustable) output pins, the output voltage can be adjusted within a certain range through resistors or potentiometers, vehicle custom-make supply and the general adjustment range is ±10%.

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.

Uninterruptible Power Supply (UPS)
An uninterruptible power supply (UPS) is a highly reliable and high-performance power supply necessary for computers, communication systems and occasions that require uninterrupted supply. The AC mains input is converted into DC through the rectifier, part of the energy is charged to the battery pack, and the other part of the energy is transformed into AC through the inverter, and sent to the load through the transfer switch. In order to still provide energy to the load when the inverter fails, another backup

vehicle custom-make 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.
