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 350 W 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 Vdc to 36 Vdc and 36 Vdc to 75 Vdc and an output
voltage of 12 V and 28 V. The output voltage is adjustable from 7.2 Vdc to 13.2 Vdc
or 16.8 Vdc to 29.4 Vdc (not to exceed 308 W for the RFB300 [300 W for the
RFB300-24S12] and 350 W for the RFB350). The series also has a remote ON/OFF
capability. Overcurrent, overvoltage and overtemperature 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.
