Ameritron ALS-500MX HF Amplifier
-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 29 MHz .
-Load Fault Protection - disables and bypasses amplifier if antenna has excessively 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.
