LM317 LM337 Servo Rectification Filter Power Supply Board AC to DC Power Supply

Description The plate is made of high quality 1 6MM double sided fiberglass board two specifications 22 30 50V 4700UF 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 lessOutput DC voltage range 1 5V input AC 1 4 times maximum DC Peak maximum output current 1 5ANote 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 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 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 not reverse the connection Do not burn the LF353 op amp block Package included 1 x Power Supply Board
