Complete automatic control of a transceiver with CAT capability* allows the amplifier to track the operating frequency and will change bands accordingly. When a CAT connection to the transceiver is not present, the amplifier will monitor the input signal frequency through the built-in frequency counter and will automatically switch bands. The ACOM 500S is transceiver independent and fully compatible with all transceiver models available and requires less than 25W of RF power and a "ground on transmit" signal for operation. The 500S utilizes a rugged LDMOS transistor and a broadband input circuit presents an SWR below 1.5 to the transceiver without re-tuning throughout the entire frequency range from 1.8 to 70.5 MHz. Built-in intelligent protection circuits continually work in the background to keep your equipment safe. Detailed data about each of the last hard-fault protection trip is stored in the amplifiers non-volatile memory for easy maintenance. Built-in radio frequency filters exceed EMC requirements by providing electromagnetic compatibility (EMC) with highly sensitive devices typically found in the shack such as receivers, computers and other amplifiers. NOTE: Compatible ACOM 04AT or 06AT Antenna Tuners are powered and controlled only by an ACOM Solid State Amplifier. Automatic operation of these tuners requires exact frequency information (not band data) from a CAT or COM (RS-232) or CI-V capable transceiver via a custom built Transceiver to Amplifier Interface Cable. The required frequency data interface cable may be user built (CAT/AUX connection instructions from ACOM) or purchased as an optional accessory from DX Engineering for applicable transceivers.

ACOM A3x2000A HF Power Splitter/Combiner
The ACOM A3x2000A HF Power Splitter/Combiner is a passive device designed to sum the outputs of three HF linear amplifiers into a common load while the amplifiers are driven by a single exciter. This allows for better signal processing, modular amplification setup, and more consistent power levels. For best results we recommend three automatic amplifiers of the type ACOM2000A. Manual tune amplifiers with a precise tuning indicator like ACOM1200, ACOM1000, ACOM1010 or ACOM1011 can be used. Models that use a broadband input network are recommended. An automatic protection circuit is implemented in the ACOM A3x2000A, which monitors the three amplifier outputs during operation. In case of an imbalance, the protection circuit cuts the drive to the amplifiers and switches transceiver output to an internal 50 Ohm dummy load. The imbalance power is swamped by powerful resistors until the protection trips. Circuit reset is accomplished by a simple push-button. Specifications: * Frequency coverage: 1.8 – 30 MHz, continuous * Power output: 5 kW PEP, VSWR < 1.3:1 * Input impedance: 50 ohm unbalanced, UHF, SO-239 connectors, broadband * 8.268 in. wide, 12.795 in. deep, 7.677 in. tall * 14.1 lbs.
