A converter is classified into AC/DC Converter and DC/DC Converter. In a communication system, it's used as a device which supplies the current which was first converted in a rectifier to each equipment. Due to this kind of power control, a lot of heat is generated. Therefore, a heat sink is attached to parts-mounted PCB BOARD. For a smooth heat sink, dual METAL PCB is applied, which in turn enhances the heat-sink performance.
