HLK-PM01 5V/3W Power Supply Module is plastic enclosed PCB mounted isolated power supply module. It can supply 5V DC from 120V AC – 230V AC and features a power rating of three Watt. This makes it perfect for little projects that needs a 5 volt supply from mains. There are many advantages for these modules, like low-temperature rise, low power, high efficiency, high reliability, high-security isolation etc.
You are doing not need to worry about fluctuations in voltage grid. it's designed to be mounted on the PCB and is that the ideal solution to power pads that you simply take. it's widely utilized in a sensible home, automation and control, communication system , instrumentation and other industries.
The HLKPM01 is usually utilized in places where a microcontroller circuit has got to be powered directly from AC mains. Most digital circuits operate at a voltage of 5V, this module can convert the AC mains to 5V with an efficiency of 70%. The module also meets the UL,CE requirements hence are often utilized in commercial products and will be free from ripple and noise.
However the module can source only a maximum of 600mA as continuous current, so if you circuit requires anything quite that then consider the HLK-5M05 module which may source upto 1A.The HLKPM-01 module may be a circuit by itself. Inside the thick recorder there are circuits to convert your AC mains on to 5V DC. So using it's pretty simple. you only need to connect the AC mains terminals to the AC pin and that we will get a 5V regulated voltage at its output terminals.
The module also has built-in short protection and over current protection. But, still you would possibly consider adding some external protection circuits supported your Power regulation and application. Commonly a fuse and a MOV is employed on the input side to guard the module from voltage and current spikes.
