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. Embedded Power for Business-Critical Continuity Rev.11.26.07 rfb300/350 2 of 6 Specifications All specifications are typical at nominal input, full load at 25 °C unless otherwise stated.
