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 2020S Solid-State 1.8-54 MHz Linear Amplifiers
ACOM 2020S Solid-State 1.8-54 MHz Linear Amplifiers are state-of-the-art 1500W Solid State linear amplifiers that deliver maximum legal power in all modes and operate in all Amateur Radio HF bands from 160 through 6 meters. This amplifier is extremely operator-friendly with a remote console unit (RCU) that features a high-resolution color touch screen. The 2020S amplifier is transceiver-independent, meaning that it is compatible with all transceiver models. With no need for special signals, only ground on transmit and RF drive power, any transceiver may be used. The 2020S monitors the input signal frequency with its built-in frequency counter and automatically switches bands when there is no transceiver frequency interface cable. However, when interfaced with a transceiver with CAT, COM or CI-V capability, the 2020S tracks the transceiver operating frequency and automatically changes bands accordingly. The Acom 2020S supports direct Remote Control via the Internet with an integrated web interface and built-in Ethernet RJ45 LAN port or Wi-Fi adapter. The Acom 2020S amplifier employs two powerful modules in a power splitting/combining technique that has been time-proven in high-power commercial applications to provide sufficient output headroom. The input and output ports are isolated from each other, reducing intermodulation and improving resistance to self-excited oscillation and reliability. A broadband input circuit provides a perfect transceiver load with SWR below 1.2 without re-tuning throughout the entire frequency range from 1.8 to 54 MHz. The two final PA stages use a rugged MRFX1K80HR5 or equivalent LDMOS transistor. The 2020S features built-in intelligence that continuously monitors system health and protection circuits in all modes. Also, the operator can monitor eleven different parameters of amplifier operation. Detailed fault data is stored in the amplifier's memory and shows up to 55 parameters for each of the last 28 hard-fault protection trips. Compact and lightweight construction with a built-in switching-mode power supply that operates within a power mains voltage range of 200-240 VAC, ±10% (180-264 VAC limiting values), with no internal switch over. The consumed current is purely sinusoidal, power factor corrected and in-rush current limited, which makes the operation of this amplifier from unstable AC mains and generators easy and trouble-free.
