All specifications are typical at nominal input, full load at 25 °C unless otherwise stated.
External output capacitance required (See Note 4) SPECIFICATIONS
RFF500/600/700 series is a high efficiency, enclosed, isolated dc-dc converter
series in an industry standard full-brick package that provides up to 700 W of
output power. The series delivers very high usable output power for today’s high
performance RF power amplifier and similar applications. The five 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 28 V. The output voltage is adjustable from 16.8 Vdc to
29.4 Vdc (not to exceed 500 W for the RFF500, 600 W for the RFF600 and 700
Wfor the RFF700). The series also has a remote isolated ON/OFF capability.
Overcurrent, overvoltage and overtemperature protection features are included
as standard. Other options are also available. Full international safety approval
including EN/IEC60950-1 VDE and UL/cUL60950 reduces compliance costs and
time to market.
