What is the role of the the 110 v input power supply?(1)
For high voltage input module power supply products with TRIM or ADJ (adjustable) output pins, the output voltage can be adjusted within a certain range through resistors or potentiometers, the 110 v input power supply and the general adjustment range is ±10%.
The distributed power supply mode has the advantages of energy saving, reliability, high efficiency, economy and easy maintenance. It has been gradually adopted by large-scale computers, communication equipment, aerospace, industrial control and other systems, and is also the most ideal power supply method for low-voltage power supply (3.3V) of ultra-high-speed integrated circuits. In high-power occasions, such as electroplating, electrolytic power supply, electric locomotive traction power supply, intermediate frequency induction heating power supply, motor drive power supply and other fields also have broad application prospects.
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 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.
