Product Overview

The 47122 from Myraa is a single output regulated switching power supply. This encapsulated electronic transformer is a switched mode power supply based on flyback topology and provides an alternative solution to traditional power supplies used in most common low powered applications. This power supply has high level of increased power, almost three times more than the standard EI30 transformer and offers a better energetic efficiency of 70% typical compared to 40% for a conventional supply and low standby power consumption. The electronic transformer has the same footprint as an EI30 transformer which replaces regulated types of transformers. This electronic transformer is ideal for use with a wide range of applications including alternative to the linear transformers in all AC to DC applications, alternative to DC to DC converters for application in DC current, standby devices and others DC or AC auxiliary supplies.
