Boosted version with (2SC-2879) Transistors<\/p>\n
HLA-300V PLUS-HP: This NEW HLA-300V Plus-HP is a high power linear amplifier designed to operate in all modes on all HF Ham Radio bands (1.8-30Mhz). In order to significantly reduce the harmonic emissions, it has been equipped with Cauer filters (elliptical) with cutting frequencies of 3\/4.5\/8\/15\/22\/31 Mhz. A microprocessor supervises on all amplifier functions. Fitted with 4 x 2SC-2879 transistors.<\/p>\n
*Founded in 1974 by Remo Marchioni in Porretta Terme, Italy, RM Italy is a name that has become synonymous with finely crafted, high-performance linear amplifiers trusted in ham shacks around the globe.
\n*Celebrating 50-Years Anniversary from 1974-2024<\/p>\n
THIS KIT INCLUDES:
\nHLA-300V Plus-HP 500W
\nE-SCN-75A Professional Power Supply 13.8 Vdc \/ 75A \/ 1000W
\nHigh-Power high quality DC cord
\nBONUS FREE: Rubberized Spacer Studs <\/p>\n
Features:
\nOutput power indicator
\nProtected against polarity inversion, over temperature, over input power and high SWR
\n6-Output low pass filters can be set manually or selected in automatic way by processor
\nForced multispeed ventilation
\nDetects the input frequency and sets the related filter when the amp is in AUT. mode.
\nDetects the input power and, if too high, puts on the -3dB attenuator to halve it.
\nChecks the heat-sink temperature and, if too high, activates the second fans speed.
\nChecks the antenna stationary waves and shutdowns the amplifier if the SWR is too high.<\/p>\n

IMPORTANT NOTE:
\nBe sure to use a high quality power supply, able to guarantee a stable output supply of 13,8V at the max power absorption. We suggest the E-SCN-1000, a professional switching power supply.
\nEnsure that the selected frequency band is correspondent to the operative frequency.
\nDon\u2019t use an input power higher than the max value indicated.
\nAvoid operating the amplifier excessively, driving it at the max input power allowed for long work sessions.
\nCheck that all links are made correctly.
\nA mismatched antenna with high stationary waves and unsuited to carry the max output power can cause permanent damages to the amplifier.
\nRespect strictly the values \u200b\u200bindicated.
\nWarranty does not cover damage caused by improper usage.<\/p>\n","protected":false},"excerpt":{"rendered":"
