Ameritron ADL-2500 Dummyload

Ameritron's ADL-2500 2500 Watt fan cooled dummy load handles any legal limit amplifier! It lets you tune up your expensive amplifier fast and safely. You'll find it handy for tuning, testing and repairing your amplifier, transceiver or transmitter and for setting power level, adjusting your mic gain and more!

Works with all amplifiers, transceiver and transmitter from DC through 6 Meters. It can dissipate 2500 watts average power for one minute on, ten minutes off. Handles 300 Watts continuous. See power curve. SWR is less than 1.25 to 1 below 30 MHz and less than 1.4 from 30 to 60 MHz.

Four 50 Ohm non-inductive super high energy density resistors are used. They're made with dispersed carbon particles fired in a ceramic matrix. Each has an incredibly high energy density of 7000 joules per cubic inch per second with a voltage gradient of 10 kV per inch! Detailed specifications and power curve is permanently silk-screened on the cabinet for each reference. A whisper quiet DC brushless fan with ball bearings generates a huge volume of air flow for efficient cooling. Use 12 VDC or 110 VAC. This heavy duty aluminum chemically treated cabinet is 9 1/2 x 8 1/4 x 4 inches. It uses PEM nuts and has a SO-239 Connector.
