AJMRTC HLK-20M09 AC-DC switching power module converts alternating household mains into steady 9V direct current. It adopts high-efficiency isolation step-down architecture with low no-load power consumption and high conversion efficiency. The reinforced isolation barrier effectively prevents electric leakage and interference between high-voltage AC side and low-voltage DC side. It works reliably for long-time continuous operation, widely used in smart home sensors, control boards, small monitoring equipment, industrial controllers and DIY electronic modification projects. Sold as a set of two modules, it is a convenient spare and bulk solution for electronic engineers and hobbyists.
