Recom Switching Power Supply, RAC02-05SE/277, 5V dc, 400mA, 2W, 1 Output, 120 → 430 V dc, 85 → 305 V ac

The ultra compact Recom 2W PCB mount RAC02-SE/277/W power 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.

One of the most important features is the extended operating temperature range, as a consequence this series of power modules can now be used in areas where temperatures drop as low as -40°C.

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.
