Ameritron mobile no tune Solid State Amplifier

AL-500MRXCE is a combination of the CE certifed AL-500MXCE and an AL-500MRXCE Remote, for 240V export.

-Mobile no tune Solid State Amplifier - uses four rugged 2SC2879 high power linear RF power transistors.

-Instant bandswitching, no tuning, no warm up - just turn on and operate - makes mobile QSOs safer.

-Very Compact - Just 3 ½" x 9" x 15" - fits in nearly any mobile installation; weighs only 7 pounds.

-Extremely quiet - quiet low speed, low volume fan stays off and silent until temperature rises.

-Output Power - 500 watts PEP, 400 Watts CW

Continuous Coverage - 1.5 to 22 MHz 10/12 Meters with easy to install optional kit.

-Load Fault Protection - disables and bypasses amplifier if antenna has excessively h high reflected power or if bandswitching is set lower than exciter frequency - virtually eliminates damage because of operating error; has Load Fault LED indicator.

-Thermal Overload Protection - disables and bypasses amplifier if temperature is excessively high; automatically resets when temp drop to safe level Thermal Overload LED indicator.

-Excellent harmonic suppression - multiple section output network, push-pull output circuit has excellent harmonic suppression.

-DC current meter lets you monitor collector current.

-ON/OFF Switch - bypasses amplifier for "barefoot" operation without having to disconnect high current power supply cables.

-Remote ON/OFF Control - lets you remote control ON/OFF function for out-of-the-way mounting of amplifier.

-Exciter Drive - less than 100 watts input gives full output.

-Power Supply Requirements - requires 14 VDC at 80 amperes peak current for PA transistors and separate line for 14 - 16 VDC at 4 amperes for control and bias circuits. Made in USA.
