Description
The ACOM 2100 (A2100) is a complete and self-contained linear amplifier that covers all amateur bands from 1.8 through 54 MHz and provides over 1500W PEP or continuous carrier output power with less than 85W exciter drive.
Easy to operate
The TRI (True Resistance Indicator) is a powerful tuning aid that, together with the automatically controlled input attenuator, helps the operator to quickly and precisely match the antenna impedance to the optimum tube load impedance (5-10 seconds typically). The AUTO-OPERATE function (when enabled) maintains the amplifier in the OPERATE mode for you, thus saving manual operations and time.
No antenna tuner needed
No external antenna tuner is required as long as the antenna SWR is 3:1 or lower. The amplifier will perform the functions of an antenna tuner, enabling you to change antennas faster and use them over wide frequency ranges.
User-friendly and durable
An amplifier that is both user-friendly and that looks after itself. It is designed to safely withstand up to 300 W reflected power, up to 100 milliseconds duration of drive spikes, drive RF “tails” after a PTT or KEY release, operator’s inadvertent tuning errors, etc. The amplifier also will not cease to function with a “soft” AC mains and will deliver more than half power at only 85% of nominal mains voltage. It can withstand voltage drops (down to zero Volts) for up to 10 milliseconds and can tolerate 15% mains voltage spikes, which is especially important on Field Day, during DXpeditions, and at portable operating events where emergency power is relied upon.
OLED comment display
All amplifier status indications are explained via detailed text displayed on the OLED (Organic Light Emitting Diode) Display. The upper line on the OLED display always reads peak forward power. LED indicators are provided for: OPERATE mode, attenuation-on (ATT), transmit (TX), selected antenna output (1, 2, or 3), and ON/OFF conditions.
Easy antenna selection
Three antenna outputs are selectable using a push-button on the front panel.
Efficient tuning
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.
Transceiver-independent
The amplifier operates without special signalling from the transceiver. It needs only “ground on TX” and 60 W RF drive power to operate at full output power.
Broadband input matching
Broadband input matching circuitry offers excellent loading characteristics for the driving transceiver, from 1.8 MHz to 30 MHz.
Single tube operation
Uses a single 4CX1000A/8168 ceramic and metal radial beam tetrode with plate dissipation of 1000 W (forced air cooled, grid-driven), which is specifically designed for class AB1 RF linear amplifier operation.
Tube protection
Permanent monitoring includes protection of plate and grid voltages and currents, as well as exhaust air temperature. The Bias Optimizer decreases the heat dissipated from the tube, and there is automatic protection against overheating in accordance with specifications of the tube manufacturer.
Output RF arc protection
Output RF arc protection is employed. This important feature safeguards the amplifier, antenna, antenna selector, and tuner against severe damage in case of possible breakdown.
High voltage protection
Design of the high-voltage power supply eliminates the danger of turn-on transients affecting sensitive devices connected to the same line (mains) circuit. Moreover, the amplifier can be configured for 8 different nominal line voltages: 100, 110, 120, 200, 210, 220, 230, or 240 VAC, 50 or 60 Hz.
Warranty
Our 2 Year Warranty INCLUDES THE TUBE (unlike most other dealers) and is backed up with full factory-backed service and repair in our own workshops here at The DX Shop. No shipping to 3rd parties and long waits. After the warranty period ends units can be sent to us for inspection/quote/repair using OEM factory parts where needed that we source direct from Acom.
