Ameritron ALS-500MX 500 Watt No Tune Solid State Mobile Amplifier

Ameritron mobile no tune Solid State Amplifier Features:

• 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.
