Description

  • ACOM 700S Solid State 1.8-54 MHz Linear Amplifiers

    ACOM 700S Solid State 1.8-54 MHz Linear Amplifiers are state-of-the art amplifiers that cover all amateur bands from 160 through 6 Meters.

    These amps provide 700 W output power (PEP SSB or CW modes). Working parameters of the amplifier are indicated on a multi-function, high-resolution 5 inch color display. Amplifier control is accomplished with only six buttons on the front panel or directly by CAT interface from the transceiver or remotely by RS232 interface.

    ACOM 700S amplifiers are compatible with all transceiver models available on the market. The broadband input matches to the transceiver with low SWR over the entire range of 1.8-54 MHz.

    Full output operation only requires a maximum of 40 watts drive and the typical “ground on transmit” (PTT) keying with no special signals required. The overall operation of ACOM 700S amplifiers is extremely simplified. Screen menus are intuitive and easy to follow and no special skill is required from the operator when changing frequency bands. The amplifier monitors the frequency of the input signal through the built-in frequency counter and automatically switches bands. A band data or CAT interface connection from the transceiver is NOT required for automatic band changing.

    These amplifiers take care of themselves during operation, due to the continuously-working protection circuits in all modes. The operator can digitally monitor more than 10 parameters concerning the working conditions of the amplifier. Detailed data (55 parameters) about each of the last 28 hard-fault protection trips is stored in the amplifier’s nonvolatile memory.

    ACOM 700S amplifiers are perfect for DXpeditions and field operation. They are extremely compact and employ light-weight construction thanks to the built-in switching-mode power supply. They operate on an extended mains voltage range** (100-120VAC and 200-240VAC) by changing only the main fuses – no internal switching is required. Please read the SPECIAL NOTE at the end of the specifications.

    ACOM 700S Solid State HF/6-Meter Amplifiers are among the finest and most modern linear amplifiers available anywhere in the world.
