Datasheet
**![NOT RECOMMENDED FOR NEW DESIGNS] ! (LAST TIME BUY: 31[ST] MAR 2026)** Features • 35mW max. no load power consumption • Efficiency up to 76% **AC/DC Converter** • Isolated output 3kVAC / 1 minute Regulated • SCP, OVP protection • Wide operating temperature range: -40°C to +85°C Converter • Universal input 85-305VAC **RACC02-SE/277/W** ~~ee __~~ Description **2 Watt** The ultra-compact wired RAC02-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 35mW **Single 3** maximum, the mini power supplies are particularly suitable for energy-saving sleep mode and stand-by 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. ## Selection Guide |Part|nom. Input|Output|Output|Efficiency|Max.
