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.
Instantaneous, automatic tuning makes slow, cumbersome band changes a thing of the past.
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.
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.
The user can store up to ten (10) sets of tuning adjustments for every frequency segment - allowing individual settings for multiple antennas on each band. VSWR can increase considerably when an antenna is operated away from its resonant frequency.Its output matching network allows the amplifier to operate at full power, even with VSWR as high as 3:1 (2:1 on 160m).
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.
RCU Size: 167 x 130 x 25mm
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 LCD 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. Information on the 12 most recent protection trips is stored in an INFO BOX for remote diagnostics via phone line, PC, and Internet.
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.
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.
Antenna matching can be achieved in less than 10 seconds and at a quarter of nominal output power, which produces lower risk of interference to other stations and greater safety to the amplifier components.
