HF/6m linear amplifier 1200W with 5" touch screen control heat pipes cooling system

his a ready power amplifier. You will need a power supply only!
Water-cooled hermetically. You can turn the power amplifier. The water will not flow.

The power supply may be for example: FlatPack2

Transistor MRF1K50H 1 pcs.

100W input power

Output power 1200W (SSB/CW)

800W for digital mode with 42V

Water cooling

Two levels of blowing. Running the second level at a copper radiator temperature is more than 50 degrees Celsius. Stop transmission for copper radiator temperature is more than 80 degrees Celsius.

Supply voltage 53V 35A
Voltage 13.8V 2A
SWR protection
Current Protection
Protection in power output
Protection against spontaneous or incorrect switching LPF.
LCD – touchscreen controller

Band switch – manual

– automatic (when using the band decoder – not included)

Installed on the cable output SO-239
TRX cable SO-239
Control 25 pin connector

Power amplifier protection device:

Protection from exceeding the output power of 1200 watts.
Protection against exceeding the maximum drain current of the LDMOS transistor.
Protection against overheating – two thresholds of operation:
when the copper radiator is heated more than + 50С – the accelerated mode of the fan operation is activated to increase the heat removal.
when the copper radiator is heated above + 80 ° C, the protection system trips, breaking the PTT circuit. Transmission is not possible.
Protection against exceeding the SWR more than 2.0: 1. The activation of the SWR protection is independent of the output power level
Protection against false / spontaneous band switching in LPF.

The activated protection channel is indicated by a lit LED on the front panel of the power amplifier. To reset the error, it is necessary to switch off and on again the power supply of 48-53.7 V.
