HLK-PM03 3.3V/3W Power Supply Module is a plastic enclosed PCB mounted isolated power supply module. It can supply 3.3V DC from 120V AC – 230V AC and has a power rating of 3 Watt.
This makes it perfect for little projects that require a 3.3 volt supply from mains. There are many advantages to those 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 is considered designing to mount on the PCB and is that the ideal solution to power pads that you simply take.
It is widely used in a smart home, automation and control, communication equipment, instrumentation, and other industries.A power supply is an electrical device that supplies electric power to an electrical load. The primary function of an influence supply is to convert current from a source to the right voltage, current, and frequency to power the load. As a result, power supplies are sometimes mentioned as electrical power converters. Some power supplies are separate standalone pieces of kit , while others are built into the load appliances that they power. Examples of the latter include power supplies found in desktop computers and consumer electronics devices. Other functions that power supplies may perform include limiting the present drawn by the load to safe levels, shutting off the present within the event of an electrical fault, power conditioning to stop electronic noise or voltage surges on the input from reaching the load, power-factor correction, and storing energy so it can still power the load in the event of a short lived interruption within the source power (uninterruptible power supply).
All power supplies have an influence input connection, which receives energy within the sort of current from a source, and one or more power output connections that deliver current to the load. The source power may come from the electrical power system , like an wall socket , energy storage devices like batteries or fuel cells, generators or alternators, solar energy converters, or another power supply. The input and output are usually hardwired circuit connections, though some power supplies employ wireless energy transfer to power their loads without wired connections. Some power supplies produce other sorts of inputs and outputs also , for functions like external monitoring and control.
