HLK-2M05 Hi-link 5V 2W AC to DC Power Supply Module is plastic enclosed PCB mounted isolated switching step-down power supply module. It can supply 5V DC from  120V AC – 230V AC and has a power rating of 2 watts. This makes it perfect for small projects that need a 5-volt supply from mains. This power supply module replaces lots of parts from the traditional power supply like diodes, voltage regulators, and transformers. Therefore there are many advantages for these modules, such as low-temperature rise, low power, high efficiency, high reliability, high-security isolation, etc.

This Power Supply Module voltage source is a switching source, so you do not have to worry about fluctuations in the voltage grid. It is designed to be mounted 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.
