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.

Measurement Bandwidth: 20 MHz; Measured with 1 µF ceramic and a

330 µF (470 µF for 12 V output model) aluminum or solid tantalum

capacitor across the output terminals.

11 Measured per ETSI 300 132-2 Section 4.7.2.

12 From 10% to 90% of Vout (nom). Full resistive load. 1 µF ceramic and

330 µF (470 µF for 12 V model) electrolytic capacitors across the output.

13 Converter guaranteed ON for positive option.

14 Maximum driver leakage to insure converter is ON.

15 Converter guaranteed OFF for positive option.

16 Driver sink current @ Vrc ≤ 1.2 V.

out

with a 1 µF ceramic and a 330 µF (470 µF for 12 V output model)

aluminum electrolytic capacitor across the output.

External input fusing required. Use a fast acting fuse: 40 A (24 V model),

15 A (48 V, 350 W model).

Iout = Iout (max) Measured with the input capacitor, Cbypass = 330 µF,

and 6 µH inductor in series with the power source. Frequencies

>100 kHz.

17 0.40 in height option is not available on the 12 V output model.

18 The’Y’ suffix indicates that these parts are TSE ToHS 5/6 (non-Pb-free)

compliant

19 NOTICE: Some models do not support all options. Please contact your

local Artesyn representative or use the on-line model number search tool

at http://www.artesyn.com/powergroup/products.htm to find a suitable

alternative

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.
