1. GENERAL INFORMATION
1-1. Inroduction and description
This manual describes the installation, operation, and maintenance of the HF+6m solid-state linear power
amplifier ACOM 600S.
ACOM 600S is a state-of-the art linear amplifier which covers all amateur bands from 1.8 through 54MHz and
provides more than 600 W output power (PEP or continuous carrier) with less than 30W of drive. The working
parameters of the amplifier are indicated on a multi-functional, high resolution color display. The amplifier control
is performed with only six buttons from the front panel, directly by CAT interface from the transceiver or remotely
– by RS232 interface.
1-2. Owner assistance
If technical or operating assistance is needed, please contact your local dealer first. In the unlikely event you
need further information, you may get in touch with ACOM as follows: fax: + 359 2 920 96 56, tel359
2 920 96 55, e-mail: acom@acom-bg.com, acom@mail.orbitel.bg or by mail to: blvd. Nikola Mushanov 151, 1330
Sofia, Bulgaria. The ACOM Internet page is: www.acom-bg.com.
1-3. Equipment supplied and options
The amplifier is supplied in single box, which includes:
- the amplifier ACOM 600S;
-
this manual with a CE declaration of compliance;
- four pieces of spare fuses;
Directly from ACOM or from your dealer you can also buy some of the following options:
- CAT interface cables for connecting the supported transceiver models (please specify the wanted one);
- Technical compact disk (CD), containing complete schematic diagrams, graphic information and parts
layouts of the printed circuit boards, as well as a list of commands set and the rules for remote control of
the ACOM 600S amplifier.
1-4. Features

5" (108x65mm) high resolution color display, 800x480 pixels, and 24-bits colors.

The final stage uses field effect (MOSFET) transistors type MRFE6VP6300H, which, according to their
manufacturer - Freescale Semiconductor - are designed to withstand high mismatch (SWR) at the output
and are intended for operation in aerospace, industrial, mobile, and radio broadcast applications.

Compatible with all transceiver models available on the market - does not need any special signals:
"ground on transmit" (PTT) and 30W of RF drive power is sufficient.

Broadband input circuit providing a perfect transceiver load with SWR below 1.2:1 (typically 1.1:1),
without retuning throughout the whole frequency range from 1.8 to 54MHz.

The overall operation of ACOM 600S is extremely simplified: the screen menus are intuitive and easy to
follow and no special skill is required from the operator when changing frequency bands.

Possibility of automatic control – when connected to a transceiver with a CAT interface, the amplifier
monitors constantly, duly follows the operating frequency, and changes the bands accordingly.

Even if not connected with CAT interface, the amplifier monitors the frequency of the input signal through
the built-in frequency counter and automatically switches over the bands.
