[COD] folp LM317 LM337 Servo Rectification Filter Power Supply Board AC to DC Module

Feature: The plate is made of high quality 1.6MM double-sided fiberglass board, two specifications 22x30,50V4700UF filter large capacitor, The layout uses a classic grounding, the two sides of the symmetrical layout, beautiful and generous. Input AC voltage requirements: 24V or less-0-24V or less. Output DC voltage range: 1.5V-input AC × 1.4 times maximum DC. Peak maximum output current: 1.5A. Note 1: This PCB power board is a buck regulator board, which has no boosting effect. If the 18V AC rectification is 25V DC, then its highest adjustable voltage is 25V. Note 2: The factory output voltage is adjusted to plus or minus 5V by default. The buyer can adjust the voltage as needed after receiving the goods. The adjustment method is to find the 3296 fine-tuning component, turn it to the left for buck, and turn it to the right for boost. Note 3: AC IN is the AC input terminal, DC OUT is the DC output terminal. When installing, pay attention to distinguish the input and output terminals. Do
