Hi Link HLK PM03 3.3V 3W Switch Power Supply Module

HLK-PM03 Hi-Link 3.3V 3W AC to DC Power Supply Module is plastic enclosed PCB mounted isolated switching step-down 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 small projects that needs a 3.3 volt supply from mains. 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 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.
