SPECIFICATIONS
RFB300/350 series is a high efficiency, enclosed, isolated DC/DC converter series in
an industry standard half brick package that provides up to 350W of output power.
The series delivers very high usable output power for today’s high performance RF
power amplifier and similar applications. The four models in the series feature an
input voltage range of 18 to 36VDC and 36 to 75VDC and an output voltage of 12V
and 28V. The output voltage is adjustable from 7.2V to 13.2V or 16.8V to 29.4V (not
to exceed 308W for the RFB300 and 350W for the RFB350). The series also has a
remote ON/OFF capability. Over current, over voltage and over temperature
protection features are included as standard. Negative logic remote ON/OFF and
other options are also available. Full international safety approval including
EN/IEC60950 VDE and UL/cUL60950 reduces compliance costs and time to market.
