ACOM 1500 HF + 6 Meter Linear Amplifiers

ACOM 1500 HF + 6 Meter Linear Amplifiers are user-friendly and look after themselves. They are designed to safely withstand up to 300 watts of reflected power and up to 100 milliseconds duration of drive spikes. These amplifiers also continue to function with "soft" AC mains and will deliver more than half power at only 85 percent of nominal mains voltage. They can withstand voltage drops for up to 10 milliseconds and can tolerate 15 percent mains voltage spikes. This level of tolerance is especially important on Field Day, during DXpeditions, and at portable operating events where emergency power is relied upon. Please see the SPECIAL Note, below. The True Resistance Indicator (TRI) is a powerful tuning aid that helps the operator to quickly and precisely match the antenna impedance to the optimum tube load impedance. The auto-operate function (when enabled) maintains the amplifier in the OPERATE mode, thus avoiding unnecessary manual operations. Your ACOM amplifier will enable you to change antennas virtually instantaneously and allow you to use your antennas over wider frequency ranges. Broadband input matching presents a very good load to the transceiver over the entire spectrum of 1.8-54 MHz. These amplifiers produce virtually-silent QSK. The input bypassing and vacuum antenna relays are virtually silent even in the CW QSK mode; thanks to specially designed mounting hardware. ACOM 1500 amplifiers utilize a single 4CX1000A ceramic and metal radial-beam tetrode vacuum tube with plate dissipation of 1,000 watts. Tube protection includes permanent monitoring and automatic protection of plate and grid voltages and currents, as well as the exhaust air temperature. These pieces of data are essential to indicate 4CX1000A operating conditions. All ACOM 1500 amplifier status indications are explained via detailed text displayed on the dot matrix, high brightness, vacuum fluorescent display (VFD). LED indicators are provided for Power, Operate mode, Attenuation-on, Transmit, Selected antenna output, and ON/OFF conditions. * Frequency Coverage: 1.8-54 MHz * Power Output: 1,500W PEP, 1,200W continuous carrier; for continuous carrier transmissions longer than 15 minutes the external auxiliary fan must be installed * Intermodulation Distortion: Better than 35dB below PEP rated output * Hum and noise: Better than 40dB below rated output * Harmonic Output Suppression: 1.8-21.5 MHz; 50dB below rated output, 24-54 MHz; 66dB below rated output * Input and Output Impedance: Nominal values: 50 Ohm unbalanced output; Input circuit: broadband, VSWR less than 1.3:1, 1.8-54 MHz (no tuning, no switching); Bypass path: VSWR less than 1.1:1, 1.8-54 MHz continuously * RF Gain: 13dB typically, frequency response less than 1dB (60-85 W drive power for rated output) * Primary Power: 100-264V (100, 110,120, 200, 210, 220, 230 and 240V nominal taps), 50-60Hz, single phase, 3500VA consumption at rated output * SPECIAL Note: Order part number AOM-1500 to wire the AC plug yourself; order part number AOM-1000-240 for pre-wired 240 volt operation * Complies with CE safety and electromagnetic compatibility requirements as well as FCC-regulations * Size: 16.6 x 14 x 7.7 in. * Weight 58.4 lbs. * Operating environments: Temperature range 0 to 50 degrees C, Humidity up to 95 percent at 35 C * Altitude: up to 3,000m (10,000ft) above sea level without output deterioration Note: For additional information, please look at the files under the "Documentation" tab.

ACOM 2000A Automatic HF Linear Amplifiers

ACOM 2000A Automatic HF Linear Amplifiers are the world's most advanced amplifiers designed specifically for hams. These amplifiers were the first to include fully-automatic tuning and sophisticated digital-control capabilities. ACOM's revolutionary 2000A amplifiers deliver maximum legal power in all modes and operate on all amateur HF bands 160 to 10 meters. Be sure to read the SPECIAL Note, below. These amplifiers follow your transceiver's band and frequency automatically in far less than a second. No special cables are required: Just a "dit" on CW or "AHH" on SSB is enough for instant band and band segment changes. ACOM 2000A amps break every amateur band into multiple frequency segments. 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. By completely eliminating time-consuming tune-up procedures, ACOM 2000A linear amplifiers give contesters a real edge. At the core of the ACOM 2000A is a classic HF amplifier design that employs two matched 4CX800A high-performance ceramic-metal tetrodes for maximum efficiency. ACOM uses these rigorously tested tubes with today's most advanced digital control technology to create an amplifier with outstanding performance, features and reliability. Measured third and fifth order IMD are typically 40dB and 45dB down, respectively. Typical harmonic emissions are as low as -55dBc (second) and below -70dBc (for third and above). Thus, probability of QRM, BCI or TVI is dramatically minimized. ACOM's 2000A remote diagnostic features and modular design ease fault isolation and repair. The protection system makes damaging one of these amplifiers difficult. Information on the 12 most recent protection trips is stored in an INFO BOX for remote diagnostics via phone line, PC, and Internet. Full break-in (QSK) is based on a built-in vacuum relay. Transmit/receive switching sequence is secured by a dedicated microprocessor. * Frequency Coverage: All Amateur Bands 1.8-29.7 MHz * Power Output: 1,500W PEP, 1,500W continuous carrier (the external auxiliary fan must be installed for operations of continuous carrier transmissions longer than 15 minutes * Hum and noise: Better than 35dB below rated output * Harmonics Output Suppression: Better than 50dB below rated output * Input and Output Impedance: Nominal values: 50 Ohm unbalanced output; Input circuit: broadband, VSWR less than 1.3:1, 1.8-29.7 MHz Amateur Bands (no tuning, no switching); Relay Bypass Throughput: VSWR less than 1.1:1, 1.8-29.7 MHz Amateur Bands * Automatic Tuning: Load Impedance Matching - less than 3 seconds; Band Change - less than one second; Segment Change - less than 0.2 seconds * RF Gain: 14.5dB, frequency response less than 0.5dB (50 to 60W drive power for rated output) * ALC: grid-current derived, -11V max, rear panel adjustable * Primary Power: 180-264V (200, 220 and 240V nominal taps, 10 percent tolerance), 50-60Hz, single phase, 3,500VA consumption at rated output * SPECIAL Note: Order part number AOM-2000A to wire the AC plug yourself; order part number AOM-2000A-240 for pre-wired 240 volt operation * Complies CE safety and electromagnetic compatibility requirements, as well as FCC regulations * Size: W 17.3 x 19.7 x H 7.1 in.
