The AL-500MX  is the AL-500M  wired 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 " 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.
