5V / 3W SMPS Module from Hi-Link is a PCB mounted plastic enclosed isolated switching step down power supply module. It can supply 5V Dc from 120V -230V AC and has a power rating of 3W. Its ultra compact size makes it perfect to use in places where size is a constraint. This power supply module replaces lots of parts from the traditional power supply like diodes, voltage regulator and transformers.There are many advantages for these modules such as low temperature rise, low power, high efficiency, high reliability, high security isolation etc. It is widely used in smart home, automation and control, communication equipment, instrumentation and other industries.
