AJMRTC LM317 LM337 positivenegative dual adjustable powersupply PCB board is a mature ACDC dualpolarity regulated power module. It uses LM317 for positive voltage regulation and LM337 for negative voltage regulation to generate stable symmetrical positive and negative DC power from AC input. Users can turn the onboard potentiometer to adjust output voltage continuously within 5V24V. This integrated PCB board omits complicated discretecomponent assembly work, directly meeting powersupply demands of operational amplifiers, analog signal circuits and teaching experimental equipment. Basic overcurrent protection reduces risks of chip damage caused by shortcircuit. Suitable for electronic lab testing, analogcircuit debugging and amateur DIY development. Please pay attention to heatdissipation installation for regulator chips under heavyload conditions; confirm inputoutput voltage difference to avoid overheating.
