The 3.3V PM03 HLK Power Supply (3.3V 3W Hi Link) is a plastic enclosed PCB mounted isolated switching Step Down Power Supply. It can supply 3.3V DC from 100V-240V AC and has a power Rating of 3Watt.
This makes it perfect for small projects that need a 3.3V supply from mains. There are many advantages to these modules, such as low-temperature rise, low power, high efficiency, high reliability, high-security isolation, etc.
This HLK Power Supply voltage source is a switching source, so you do not have to worry about fluctuations in voltage grid. It is considered designing to mount on the PCB and is the ideal solution to power pads that you take.
It is widely used in a smart home, automation and control, communication equipment, instrumentation, and other industries.
