Converter
• Universal input 85-305VAC RAC02-SE/277
ee—
Description 2 Watt
The ultra-compact RAC02-SE/277 modules are available with output voltages of 3.3, 5, 12 and 3
24V, and the input-to-output isolation is 3kVAC/1min. With a standby consumption of 35mW Single Carrasty
maximum, 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 Output
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.
