• HF amplifier AL-500MRX for amateur radio

The AL-500MRX is a combination of an AL-500MX and an ALS-500RC Remote wired for 240V for export. This amateur radio HF amplifier uses four robust RF linear power transistors 2SC2879. Instantaneous band switching, no tuning, no preheating, just turning it on and using it, makes the mobile QSOs safer. Very compact, only 3 ½ "x 9" x 15 "This HF amplifier is suitable for almost all amateur radio mobile installations, weighs only 7lbs.Extra quiet, low speed, low volume fan remains off and quiet up the temperature increases Output power - 500 watts PEP, 400 watts CW Continuous coverage - 1.5 to 22 MHz 10/12 meters with optional kit easy to install Protection against charge faults, disables and bypasses amplifier if the antenna has too much reflected power or if the band switching is less than the frequency of the exciter, virtually eliminates any damage due to a malfunction, it has a LED indicator Load Fault. thermal, disables and bypasses the amplifier if the temperature is too high and resets automatically when the temperature drops to the safe level. thermal load, excellent harmonic suppression, multi-section output network, push-pull output circuit provides excellent harmonic suppression. The DC current meter allows you to monitor the current of the collector. A switch allows you to bypass the amplifier for operation without having to disconnect the high voltage power cables. The remote ON / OFF control allows you to remotely control the ON / OFF function for off-channel editing of the amplifier. The Ameritron ALS-500MRX versions are identical to the ALS-500MX amplifiers, with the addition of the ALS-500RC remote control unit.

* Load fault protection disables and bypasses amplifier if antenna has excessively high reflected power or if band switching is set lower than exciter frequency, virtually eliminates damage because of operating error
* Load fault LED indicator
* Thermal overload LED indicator
* Thermal overload protection disables and bypasses amplifier if temperature is excessively high, automatically resets when temperatures drop to safe level
* 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
* Power supply requirements, 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.
