With a standby consumption of 35mW maximum, the mini power supplies are particularly suitable for energy-saving sleep mode and stand- Output 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. Selection Guide Part nom. Input Output Output Efficiency Max.
