Features Regulated Converter Description 35mW max. no load power consumption Efficiency up to 76% Isolated output 3kVAC / 1 minute SCP, OVP protection Wide operating temperature range: -4 C to +85 C Universal input 85-35VAC The ultra-compact wired 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 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 EN5532, 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/UL695-1 certified and come complete with a 3 year warranty. AC/DC Converter 2 Watt Single Output Selection Guide Part nom. Input Output Output Efficiency Max.
