Features Regulated Converters • 30mW max. No Load Power Consumption • High Efficiency up to 80% • Isolated Output 3kVAC / 1 min • SCP, OVP Protection • Wide Operating Temperature Range: -40°C to +85°C • Universal Input 85-305VAC AC/DC Converter RAC03-SE/277/W 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 EN55022, 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. 3 Watt Single Output 3Y EAR 3 wa rranty Selection Guide Part Input Output Output Efficiency Max.
