AJMRTC HLK-PM03 isolated AC-DC power module converts mains AC voltage into clean 3.3V DC power for low-voltage electronics. The integrated isolation design separates high-voltage AC side and low-voltage DC side to improve circuit safety and anti-interference ability. It comes sealed in a mini plastic housing, ready for direct soldering onto PCBs. It is widely adopted in intelligent household switches, wireless sensors, relay drive circuits and other embedded low-power projects.
