General description of the OM2000A+ automatic amplifier The automatic linear amplifier OM2000A+ is designed for all short wave amateur bands from 1.8 to 29 MHz (including WARC – bands) + 50 MHz and all modes. It is equipped with a ceramic tetrode FU-728F. Specification of OM2000A+: Frequency coverage: Amateur bands 1.8 – 29.7 MHz including WARC + 50 MHz Power output: 2000+ W in SSB/CW on HF bands, 1500 W in RTTY 1500 W CW/SSB on 50 MHz Drive 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: 3:1 SWR protection: Automatic switching to STBY when reflected power is 350W or higher Intermodulation distortion: better then -32 dBc Suppression of harmonics: min -50 dBc (30–54 MHz better than -70dBc) Response speed of AUTO tune: less than 0,5s within same BAND ,less than 3s if out of BAND Supported TRXs-CAT: ICOM, ELECRAFT, KENWOOD, TEN-TEC ORION, YEASU, Icom transceive protocol using by microHAM devices – CI-V OUPUT, Flex Radios and Anan ( Apache Labs ) Tube: FU-728F ceramic tetrode Cooling: Centrifugal blower + axial blower Power supply: Switchable 220,230,240V – 50/60 Hz or other primary voltages (for example 200V 50/60Hz for Japan) Transformers: 1 toroidal transformer 3.0 kVA Protection circuits: - SWR too high - Anode current too high - Screen current too high - Grid current too high - Mistuning of power amplifier - Temperature to high - Soft start for fuse protection - “switch –on blocking “ at opened amplifier Indications: 4.3" colour touch screen display Features: - Support automatic external Antenna switching - Memory for faults and warning, easy maintenance - Automatic set-up anode current (BIAS) – no need to manual adjust after changing the tube - Automatic set-up of blower speed according to temperature - T/R System: QSK operation with built-in vacuum RF antenna relay - Remote control - connector for LAN connection - The smallest and lightest 2000 W automatic PA on the market Mechanical parameters: 390mm x 195mm x 370mm (width x height x depth) Weight: 24 kg LAN Connection Power amplifier is interfaced to LAN via XPORT made by Lantronix (type XP1001000-05R). More info can be found at www.lantronix.com . Default factory settings of XPORT are: IP address: 192.168.1.211 Mask: 255.255.255.0 Gateway: 192.168.1.1 These are strictly default settings. You can modify any of these by going to XPORT web GUI via your web browser. We do not recommend changing any other parameters of the XPORT interface as loss of communication can be caused by doing so. There is no default user name or password. It is highly recommended to secure web interface with username and password. For remote control and monitoring over LAN special software is needed. It is available free of charge; it can be downloaded from the following address: http://www.om-power.com/download/HF_PA_Manager_v3.14-setup.exe.
