[xlmodel]-[phot The HLK-PM series mini AC-DC power supply modules include HLK-PM01, HLK-PM03 and HLK-PM12 models, providing three mainstream output voltages: 5V, 3.3V and 12V. This high-efficiency isolated power module can directly convert 85-265V AC mains voltage into stable DC low voltage, which perfectly meets the power supply demands of low-voltage intelligent electronic equipment. It is widely applied for intelligent household switches, IoT control boards and small electronic DIY projects. This compact power module adopts professional isolation design with 3KV isolation voltage, effectively isolating strong current and weak current to improve equipment safety. The rated output power reaches 3W, with extremely low no-load power consumption below 0.1W, which is energy-saving and environmentally friendly. Featuring low ripple, low noise and precise voltage output with ±0.2% voltage accuracy, the module delivers steady current without voltage fluctuation. Built-in multiple protection circuits including overcurrent protection, short circuit protection and surge protection, this power supply board can effectively avoid chip burnout caused by abnormal circuit conditions. The module is sealed with high-quality thermal conductive glue, possessing excellent moisture-proof, shockproof and dustproof performance, adapting to complex indoor working environments. The ultra-small lightweight structure saves installation space and supports simple pin welding and embedded installation. HLK-PM01 outputs stable 5V voltage with maximum 700mA current; HLK-PM03 provides 3.3V 1A low-voltage power; HLK-PM12 offers 12V 250mA power supply. Multiple specifications fully cover common low-voltage power requirements. It has wide compatibility and can match single-chip microcontrollers, relay modules, sensor equipment, intelligent switches and IoT circuit boards. With mature circuit design, stable performance and long service life, this series of AC-DC power modules is the best replacement for traditional bulky transformers. It is an essential miniature power accessory for smart home renovation, industrial control detection, electronic experiment debugging and daily electronic DIY production.
