AJMRTC ACDC adjustable positivenegative dual power supply PCB module adopts mature LM317 and LM337 voltageregulator chip solution. It converts AC input into stable adjustable positive and negative DC power, which can output dualrail voltages such as ±5V, ±12V, ±24V by adjusting potentiometer. The integrated PCB completes all peripheral matching circuits, users only need to access AC input and adjust potentiometer to obtain required dualpolarity DC voltage. Builtin thermal protection function prevents chip damage caused by overheating. This module is suitable for audio amplifiers, analog circuit experiments, laboratory debugging and various DIY electronic equipment transformation. Please confirm input AC voltage range and load current before poweron operation to avoid module burnout.
