Description
The ultra-compact wired RAC02-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 35mW
maximum, the mini power supplies are particularly suitable for energy-saving sleep mode and stand-
by 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.
