30mW max. no load power consumption Features High efficiency up to 80% AC/DC Converter Isolated output 3kVAC / 1 minute SCP, OVP protection Regulated Wide operating temperature range: -40C to +85C Converter Universal input 85-305VAC RAC03-SE/277RAC Description 3 Watt The ultra-compact RAC03-SE/277 modules are available with output voltages of 3.3, 5, 12 and Single 24V, and the input-to-output isolation is 3kVAC/1min. With a standby consumption of 30mW maximum, the mini power supplies are particularly suitable for energy-saving sleep mode and Output 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. Selection Guide Part nom. Input Output Output Efficiency Max.
