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.
