Operational insulation system
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.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated.

Measurement Bandwidth: 20MHz; Measured with 1µF ceramic and a
330µF (470µF for 12V output model) aluminum or solid tantalum
capacitor across the output terminals.
Di/dt = 1A/µs; ∆I
out
= ±25% Iout (max); Vin = Vnom; Iout = Inom. Tested
with a 1µF ceramic and a 330µF (470µF for 12V output model) aluminum
electrolytic capacitor across the output.
External input fusing required. Use a fast acting fuse: 40A (24V model),
15A (48V, 350W model).
Iout = Iout (max) Measured with the input capacitor, Cbypass = 330µF,
and 6µH inductor in series with the power source. Frequencies >100kHz.
Signal line assumed <3m in length.
This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand-alone product.
Negative remote ON/OFF option also available. Add suffix ‘-R’ to part
number, for example see part numbering system.
With the enable signal asserted, this is the time from when the input
current reaches 10% of the final steady state value until the output
voltage reaches 10% of the nominal output value. Start-up into resistive
load.
With Vin > Vin (min) applied for a minimum of 1 second, this is the time
from when the primary ON/OFF signal is activated until the output
voltage reaches 10% of the nominal output voltage.
Notes Contd.
