Modern 1kW HF linear amplifier EB104 project

  

GOOD DEAL FOR THIS FEATURES AND POWER imd ok. SEE "EB104" project - many URL in internet plus youtube >> " EB104"! 1w-30w 5w-200w 10W-400W 15w-900w 25w-1100w. Auto switch HF bands - built-in band decoder frequency counter (work from 10-12W) - ALC - SWR protection (now 2.2 - but can be adjust)- temperature-over-voltage - shows the voltage and current - integrated high power flatrack2 - three speed fan is showing the temperature-SWR - Power out not heated no noise - the fans are not audible.

PS built IN may be 110 or 220 VAC. 1000W HF MOSFET power amplifier. Operation frequencies 1.8 30 MHz. MAX Input power 29 37 W.

Power supply 13.8VDC, 50VDC -built in 110/220VAC. Drain current max 26 29 A.

SWR on output higher than 2.0:1. It has two levels of air cooling fan speed: normal and forced.

Forced mode is engaged when copper heat spreader plate temperature rise above 50C. If temperature rise above 80C the PTT line is being disabled.

Both thermo sensors has 10C hysteresis. Two lines LCD shows the output power in Watts and SWR on output. Second line is output power bar graf. Protection status LEDs are placed on boards, but could be transferred to the front panel.
