ALS-500M
 


 
--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 1/2 x 9 x 15 Inches -- 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.

ALS-500RC
 

 
The Ameritron ALS-500RC is a remote control head for the Ameritron ALS-500M amplifier with serial number 13049 and above. (For ALS-500M units with a serial number below 13049, you can purchase the ARF-500K remote kit to modify your ALS-500M to use the ALS-500RC) The ALS-500RC allows the amplifier to be located away from the operating station and still have access of the amplifiers front panel controls. The ALS-500RC operates the amplifiers power switch and frequency select switch. The ALS-500RC has LEDs to indicate power, transmit and overload. It also has a current meter.
