OM Power OM-2000A+ HF Plus 6 Meter 1,500W+ Auto Tune Linear Amplifiers

OM Power OM-2000A+ HF Plus 6 Meter 1,500W Auto Tune Linear Amplifiers (OMR-OM-2000A) features an FU-728F Ceramic Tetrode tube capable of providing stable, full legal limit all-mode output power and frequency coverage of the Amateur bands ranging from 1.8 to 29.7MHz plus 50MHz. CW ops will enjoy QSK (full break-in) with a silent T/R vacuum relay. The Intuitive 4.3-Inch color Touch Screen and front panel indicators allow you to stay informed about the operational status of the amplifier and effortlessly gain access to advanced features and settings. Full band change or frequency reading compatibility is built in for modern transceivers and RF Sense band change supports legacy transceivers. The OM-2000A+ supports automatic antenna switching for up to 10 antennas. Remote Control operation is supported via LAN and available PC program download. The OM-2000A+ is considered one of the most compact and lightest 1500W+ HF automatic tuning amplifiers on the market.

The OM Power OM-2000A+ Amplifier features an arsenal of protection circuits that will guard against high SWR, excessive current, voltage errors, excessive temperatures and more. A mechanical safety switch provides “switch-on” blocking and protects the user from potential hazards by not allowing the amplifier to power on when the case is opened. These amplifiers are also equipped with safety devices to ensure that the output relay is not mistakenly switched under power (hot switching). Built-in Memory for faults and warnings makes troubleshooting a breeze and helps to quickly identify issues and resolve them, ensuring uninterrupted performance. With built-in Automatic Anode Current (BIAS) Adjustment, there is no need to make complicated manual adjustments after changing the tube.

The 2-speed centrifugal fan and external axial fan provides the necessary cooling of the amplifier, even during long contests. The blower is activated by switching the PA on and it is turned off when cooling is finished (approx. 1-5 min after switching off the PA depending on the temperature of the tube) and the blower working mode is programmable with up to 3 modes. As one of the most compact 1,500W+ linear amplifiers available, transporting the OM-2000A+ is made easier with an HV transformer that is removable to reduce the weight of the amplifier.

Remote operation is supported via LAN port (Ethernet) and PC program download, enhancing control of the amplifier. The user can remotely switch the amplifier ON and OFF, switch between STBY and OPERATE, switch between pre-programmed antennas, read and reset the last 20 warnings and fault messages, manually fine tuning of the PA Tune and Load, check operating parameters, selection for PC display of the amplifier screen and antenna retuning if parameters change.
