E224736
Description
The ultra-compact wired RAC03-SE/277/W modules are available with output voltages of
3.3, 5, 12 and 24V, and the input-to-output isolation is 3kVAC/1min. With a standby
consumption of 30mW typical, the mini power supplies are particularly suitable for energy-saving
sleep mode and standby applications. Because of its compact design (height <18mm), it is a
versatile solution for home automation and other similar applications. Complete with an integrated
input filter, the series has enhanced EMI performance and complies with EN55032, class B. The mini
power supplies are also protected against short circuit with fully automatic restart after the error has
been solved. The converters are EN/UL60950-1 certified and come complete with a 3 year warranty.
