The ACOM 2000A represents a major advance in state-of-the-art in HF amplifier design. It changes forever the way hams use HF power amplifiers in theirs stations.
Instant, automatic tuning makes slow, cumbersome band changes a memory of the past.

A new standard of amplifier features and performance : An integrated wide-range tuner antenna corresponds loads with high VSWR (up to 3:1), often eliminating cost and complexity of a high-power, external antenna tuner.
control permissions digital RS-232 complete integration into any station configuration computer-driven. Advanced protection circuits ensure amplifier safety under any potential combination of operating conditions. Remote functions diagnostics and modular design facilitates fault isolation and repair.

Cutting-edge technology Enhance a classic design
At the heart of the ACOM 2000A is a Classic HF amplifier design, employing two high-performance Svetlana 4CX800A (GU74B) performance metal ceramic tetrodes operating in a grid-driven configuration. This design was chosen for its inherent stability and extremely low production of spurious emissions. ACOM coupled this tried-and-true setup with technology today's most advanced digital control to create an amplifier with performance exceptional features and reliability.

Signal : Excellent transceiver load (typically below 1.2:1 input VSWR), and regulated SG voltage result of extremely low distorted output. Typical measured IMD are - 40dB (order 3-rd) and - 45dB (5-th order). Classic Pi-L mains, all coils with air (without ferrite), and the carefully designed layout of the outlet tank deliver emissions typical low harmonics as low as - 55dBc (second) and below - 70dBc (third and above). Thus, probability of QRM, BCI or TVI is dramatically minimized.

Adjustment completely automatic
The automatic tuning functions in ACOM 2000A represent a real revolution in the design of HF amplifiers. Never think to an ATU for VSWR up to 3:1 (2:1 at 160 m). Match the antenna impedances real to the optimal tube loading is fully automated. Typically 1 second and no skill is required.By completely eliminating setup procedures point in terms of time, the ACOM 2000A has given contestants a real advantage. Now it is possible to change the bands, without a moment's thought. It is possible to work each multiplier identified using point-and-shoot software - independently from the band. And always knows the amplifier is properly tuned and that operate safely. The amplifier follows the band and frequency of the transceiver automatically in less than a second. No special cables are needed. Only a dot on CW or "Ah" on SSB are enough The ACOM 2000A breaks every band amateur in frequency segments. User can store up to ten (10) series of optimization adjustments for all frequency segments - which allows Individual settings for multiple antennas on each band. VSWR may increase considerably when an antenna is driven by its resonant frequency. Unlike other amplifiers on the market today, the output matching network ACOM 2000 allows the amplifier to operate at full power, even with VSWR as high as 3:1 (2:1 at 160m).

Advanced Digital Control: Control microprocessor improves performance and makes possible a wide range of new advanced functions.

QSK
Full break-in (QSK) based on a built-in vacuum relay. Transmit / receive Switching sequence is guaranteed by a dedicated microprocessor.

Remote Control Unit: RCU Dimensions: 167 x 130 x 25mm (6-2/3" x 5-1/8" x 1").
Only the remote control must be positioned close to the operator. The main unit can be installed up to 3 meters (10 feet) away. RCU features include: amplifier status displayed on the LCD display, control of all functions, measurement and/or monitoring of the 20 most important parameters, on-board technical assistance, Troubleshooting tips, record power-on hours, password provided.

Easy maintenance
The protection system makes damaging the amplifier a difficult job. Information about the 12 most recent protection trips is stored in an INFO BOX for remote diagnostics via telephone line, PC and Internet.

RS232 and network: All functions they are accessible from a PC via the RS232 serial port. Local network may include unit/antenna more than one working set amplifier in a system.

Protection
All tube voltages and currents, supply voltages, overheating, overdrive, insufficient cooling air flow, internal and external RF arcs (in amplifier, antenna selector, tuner or antennas), T/R sequencing, hot switching antenna relay contact, corresponding antenna quality, power reflected, stored data, inrush current and interlock for safety of the operator. Antenna matching can be done in less than 10 seconds and at a quarter of the rated power, which produces a lower risk of interference with other stations and greater safety to the amplifier components.
