The HLA-300V HP is an high-power linear amplifier designed to operate in all modes on all HF ham radio bands (1.8-30 Mhz). 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 amplificator functions:
➢ Detects the input frequency and sets the related filter when the amp is in AUT. mode;
➢ Detects the input power and, if too high, puts on the -3dB attenuator to halve it.
➢ Check the heat-sink temperature and, if too high, activates the second fans speed.
➢ Checks the antenna stationary waves and shutdowns the amplifier if the SWR is too high.
Transistor: 2SC2879 HP
Frequency: 1.8-30 Mhz
Current absorption: Max 60A
Input power SSB-FM: Max 35W
Input power AM: Max 25W
Average output power: 500W SSB-FM
Fuses: 4 x 16A
Bypass power: Max 100W
Harmonic values (average): -45 dB
➢ Be sure to use an high-quality power supply, able to guarantee a stable
output tension of 13,8V at the max power absorption. We suggest the
E-SCN-1000, a professional switching power supply available on our webshop.
➢ Ensure that the selected frequency band is correspondent to the operative frequency.
➢ Don't use an input power higher than the max value indicated.
➢ Avoid to stress the amplifier excessively, driving it at the max input power allowed for long work sessions.
➢ Check that all links are made correctly.
➢ A mismatched antenna with high stationary waves and unsuited to carry the max output power can cause permanent damages to the amplifier.
➢ Respect strictly the values indicated. Warranty does not cover damages caused by improper use.
Please, note that the real max output power of the HLA-300V PLUS standard version is 300W PEP (it's assembled with 4 SD1446, about 80W each) and not 550W PEP, as declared by many unauthorized resellers.
