Refer to Application Notes
Descritption The ultra-compact wired RAC03-C/277/W modules are available with output voltages of
3.3, 5, 9, 12, 15, and 24V, and the input-to-output isolation is approximately 3kVAC/1min.
With a standby consumption of 30mW typical, the mini power supplies are particularly
suitable for energy-saving sleep mode and standby applications. Because of its compact
design (height <17 mm), 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.

Notes:
Note1: Ripple and Noise is maximum peak-to-peak voltage value measured at output within 20Mhz bandwith, at rated line voltage and output load ranges.
Note2: Constant Current operation region is within 45% - 90% of Vo, nom. The Range includes all the tolerance of current precise, line regulation and load
load regulation. Typically, the current tolerance could be within ±7% at rated input voltage and output operation region for every single unit.used
Note3: „Total Regulation“ is the output voltage tolerance which includes initial voltage precise, thermal drift, line regulation and load regulation at rated input
voltage and load condition.
