  1. The product is designed to meet the requirements of the EMC and Safety Test
  2. Low power consumption, environmental protection, no-load loss <0.1W

HLK-PM03 3.3V/3W Switch Power Supply Module is a 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 need a 3.3 volt 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 Power Supply Module 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.
