Description
The modules of the RAC03-SER/277 series are regulated AC/DC converters with 3kVAC isolation and a
round, flat shape. This series has been designed to offer low stand-by consumption and an ultra-wide
input voltage range. Uses include a variety of applications in building automation, security systems and
communication systems.
