Save energy and production costs with Myrra 47000 switch-mode power supplies

Series 47000, designed as a direct replacement of classic transformers brings more than you might expect.

This is an archive article published 07/13/2012. Some information may no longer be up to date and in line with the current state. Please contact us in case of interest.

Myrra 47xxx SMPS overcome supersedes classic transformers by an overall efficiency, power as well as by a standby power consumption. With the same pinout as 1W EI30 transformers, it provides a 5W power, or up to 5,4W at some models. All this for the price comparable with a classic solution, but with smaller dimensions, without any additional components and without problems with cooling. Next to basic features represented to you in a separate article Switching power supply from Myrra already available on the stock. Try it!, we bring you a more detailed description of particular versions.

There are 4 main groups available:

● 2,5 and 5W with 1 regulated output, with 3,3 to 24V output voltage

● 3,2 and 5W (5,4W) with 1 non-regulated output, with 9 to 24V output voltage

● 3 to 5W with 2 regulated outputs with common “0” terminal

● 3 to 5 w with 2 isolated outputs. Only output no.1 is regulated and from this output it´s possible to take more power than from the output no. 2

47000 series power supplies feature a very low standby power consumption –only 200 mW or 300 mW respectively - at regulated types. With the 4000VAC isolation (input/output), they´re ready for a classs II – reinforced isolation . Operating ambient temperature is from -25°C to Ta, which can be found in a table at each type. To a simple usage also contributes a shortcut protection and a thermal shutdown with automatic recovery. More information will provide you the following tables and the Myrra 47000 datasheet.
