Description
The RAC05-K/480 series of 5 watt AC/DC units are specially designed for harsh industrial and outdoor
mains conditions. These PCB-mount power supplies are rated to OVC
III
conditions from 100-480VAC
nominal input lines with phase-to-phase or single phase operation without any external components
needed. The modules support an operating temperature range from -40°C to +80°C and come with
fully protected outputs as well as EMC Class B compliance. All these features make them an ideal fit for
integration into smart grid, renewable energy, smart metering and IoT applications.

Notes:
Note6: Refer to local safety regulations if input over-current protection is also required. Recommended fuse type: slow blow
This product can also be used with a DC supply if an appropriately rated external fuse is used. Recom recommends a 600mA, 1kVDC fuse
with a 10kA interrupting rating.
Note7: For repeat Hi-Pot testing, reduce the time and/or the test voltage
