ACOM 2000A Automatic HF Linear Amplifier 1500W 160-10m

  

The ACOM 2000A Automatic HF Linear Amplifier is the world's most advanced HF amplifier designed for amateur use. The ACOM 2000A is the first amateur HF amplifier to include both fully automatic tuning and sophisticated digital control capabilities. This revolutionary new amplifier delivers maximum legal power in all modes and operates on all HF amateur bands. The ACOM 2000A represents a major advance in the state-of-the-art in HF amplifier design. It changes forever the way radio amateurs employ HF power amplifiers in their stations. Instantaneous, automatic tuning makes slow, cumbersome band changes a thing of the past. A built-in, wide-range antenna tuner matches loads with high VSWR (up to 3:1), often eliminating the cost and complexity of an external, high-power antenna tuner. RS-232 digital control permits full integration into any computer-driven station configuration. Advanced protection circuits ensure amplifier safety under every potential combination of operating conditions. Remote diagnostic features and modular design ease fault isolation and repair. At the core of the ACOM 2000A is a classic HF amplifier design, employing two Svetlana 4CX800A (GU74B) high performance ceramic metal 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 configuration with todays most advanced digital control technology to create an amplifier with outstanding performance, features and reliability. Measured typical IMD are - 40dB (3-rd order) and - 45dB (5-th order). The automatic tuning features in the ACOM 2000A represent a real breakthrough in HF amplifier design. Never think about an ATU for VSWR up to 3:1 (2:1 on 160 m). Matching the actual antenna impedances to the optimum tubes load is completely automated. Typically 1 second and no skill is required. By completely eliminating time-consuming tune-up procedures, the ACOM 2000A has gives contesters a real edge. It is now possible to change bands without a moments thought. You can work every multiplier spotted using software point-and-shoot, regardless of band. And always know the amp is properly tuned and operating safely. The amplifier follows your transceiver's band and frequency automatically in less than a second. No special cables are required. Just a dot on CW or "Ah" on SSB are enough. Microprocessor control improves performance and makes possible a wide range of new, advanced features. Full break-in (QSK) based on a built-in vacuum relay. Transmit / receive switching sequence is secured by a dedicated microprocessor. Only the Remote Control Unit needs to be placed near the operator. The main unit can be installed up to 3 meters (10 feet) away. RCU features include: amplifier status shown on LC display, control of all functions, measuring and/or monitoring of the 20 most important parameters, on-board technical assistance, troubleshooting suggestions, record of power-on hours, password provided. The protection system makes damaging the amplifier a difficult job. All functions are accessible from a PC via RS232 serial port. Local network may include more than one amplifier / antenna unit set working in a system. The ACOM 2000A offer protection against all tubes voltages and currents, supply voltages, overheating, overdrive, insufficient flow of cooling air, internal and external RF arcs (in the amplifier, antenna selector, tuner or antennas), T/R sequencing, antenna relay contact hot switching, antenna matching quality, reflected power, stored data, inrush power-on current, and cover interlock for operator safety. Constant carrier modes 1500W RF output - no time limit with auxiliary cooling fan. Frequency coverage: All amateur bands 1.8-24.5 MHz. 28 Mhz only with modification by licensed amateurs. Bandchange / Tuneup: Initial output matching process in less than 3 secs (typically 0.5 secs). Output tolerance: Up to 3:1 VSWR (2:1 on 160m) at full rated output before SWR protection circuit actuates. Higher SWR's tolerated at lower output. Harmonics: At least 50 dB below peak output at 1500W. Intermodulation: At least 35 dB below peak output at 1500W. T/R and keying: Vacuum Relay: QSK capable. ALC: Negative going, grid derived, -11v max, rear panel adjustable. Remote Control Unit provides flexible monitoring of all amplifier operating parameters. Protection: Grid and screen current limiting, power inrush (soft-start provided), trip to excessive reflected power, RF arcs, password access protection if needed, correct T/R sequencing, tube exhaust overheat, cover interlock and HV crowbar. Fault diagnosis: Remote Control Unit display and LED's plus "INFO Box" for 12 most recent events. Transformer: 3.5 kVA with strip-wound Unisil-Hâ core. AC power requirements: 100/120/200/220/240 VAC nominal. 3500VA single phase at full power. RF Unit: 440W x 180H x 450D mm. 135 X 25H X 170D mm. Plug in transformer for ease of installation and transport. No controls on RF unit except ON/OFF. RF unit may be located up to 3 metres (10m with optional kit) from RCU.
