OM2500 HF:
Frequency coverage: amateur bands 1.8 – 29.7 MHz including WARC
Power output: 2500 W in SSB and CW 2000 W in RTTY, AM and FM
Driver Power: 40 to 60 W for full Output Power Input impedance: 50 Ohm
VSWR < 1.5 : 1 Output amplification: 17 dB Output impedance:
50 Ohm unbalanced Maximum output SWR: 2:1
SWR protection: automatic switching to STBY , when reflected power is 350W or higher Intermodulation distortion: 32 dB below nominal output Suppression of harmonics: < -50 dBc
Tube: FU-728F Ceramic tetrode Cooler: Centrifugal blower + axial blower
Power supply: 2 x 230 V - 50 Hz one or two phases Transformers: 2 pcs of toroidal transformer 2.0 kVA
Protection circuits: - SWR too high - Anode current too high - Screen current too high - Grid current too high - Mistuning of power amplifier -
Soft start for protecting your fuses - “switch –on blocking “ at opened amplifier Bar graph indications: - Power output – bargraph 50 LED - Reflected power – bargraph 20 LED - Current at screen ( Ig2 – bar graph 10 LED )
