3-1/8" EIA, Unflanged
10 kW, Forced-Air Cooled Terminations
Termaline Series RF Coaxial Terminations
The 8578B100 Series TERMALINE Loads are forced-air cooled, high-power RF Loads designed to be quiet, rugged and trouble free. This series is capable of dissipating RF line power of 10 kW at low VSWR up to 108 MHz. The RF sections are composed of a parallel combination of resistors. Virtually maintenance free and simple to operate, the unit will provide years of trouble free operation. The RF input connector is located on the top center of the unit. Perforated side panel grilles at the top and bottom of the units allow for direct forced air cooling of the resistors. The ac power receptacle, ON/OFF switch and transmitter interlock are located on the front panel of the unit. The rear and side panels are removable for servicing.
Forced-air cooled load especially suited for AM and FM Broadcast transmitter applications up to 10 kW
A.C. power input for blower operation is switch selectable 115 V or 230 V
Interlock control circuit provides fail-safe protection of the transmitter and load resistor in the event of an ac power failure to the blower
