HLK-PM01L Open Type Module

The HLK-PM01L Open Type Module is a compact, isolated AC-to-DC power supply module designed to convert mains AC voltage directly into a regulated low-voltage DC output. Built for embedded and space-constrained designs, it integrates transformer isolation, rectification, regulation, and protection on a small PCB. The open-frame form factor makes it suitable for integration inside enclosures, control boards, and IoT devices requiring reliable mains power conversion.
