8640B Series, 25 kW, Forced-Air Cooled Terminations are available in models to work with 115 or 230 volts at 50 or 60 Hz. This compact high-power 50-ohm termination efficiently dissipates up to 25 kW of RF over a wide frequency range up to 1 GHz. The RF input connector is located in the center of the side of the nearly cube-shaped unit.
Forced-air heat exchanger cooled load for high-power applications up to 1 GHz
Compact, low-profile design saves space in crowded transmitter sites
Interlock control circuit provides fail-safe protection of the transmitter and load resistor in the event of an ac power failure to the blower or coolant pump
8640b系列，25千瓦風冷式終端可在115或230V在50或60赫茲的電壓工作。這種緊湊型高功率50歐姆終端有效地消散到射頻功率25在很寬的頻率范圍高達1 GHz。射頻輸入連接器位于正方形側面中心。
強制空氣熱交換器冷卻負荷大功率應用到1 GHz
結構緊湊，低剖面設計節(jié)省空間
聯(lián)鎖控制電路提供**保護的變送器和負載電阻在發(fā)生交流斷電的風機或水泵·
