What is the role of the non-standard customization?(1)

For wide range input power supply module products with TRIM or ADJ (adjustable) output pins, the output voltage can be adjusted within a certain range through resistors or potentiometers, non-standard customization and the general adjustment range is ±10%.

Power active filter is a new type of power electronic device that can dynamically suppress harmonics. It can overcome the shortcomings of traditional LC filters and is a promising harmonic suppression method. The filter consists of a bridge switching power converter and a specific control circuit. The difference from the traditional switching power supply is: (1) not only feedback the output voltage, but also feedback the average input current; (2) the current loop reference signal is the product of the voltage loop error signal and the full-wave rectified voltage sampling signal.

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.

non-standard customization 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.
