1. GENERAL INFORMATION
1-1.
Inroduction and description
This manual describes the installation, operation, and maintenance of the HF+6m solid-state linear
power amplier ACOM 1200S.
ACOM 1200S is a state-of-the art linear amplier, covering the amateur bands from 1.8 to 54MHz with
1000W output power (PEP or continuous carrier) with less than 50W of drive. The amplier operating
information is shown on a multi-functional, high resolution color display. ACOM 1200S may by controlled
either by the six front panel buttons or remotely – by an RS232 port.
NOTE
ACOM 1200S is designed to work with ACOM 04AT
Remote Automatic Antenna Tuner. The connection of ACOM
04AT will make accessible the features that are inactive on
the amplier display when ACOM 1200S operates without
ACOM 04AT. The operation of ACOM 1200S with ACOM
04AT is described in the ACOM 04AT Operation Manual.

Features
• 5“ high resolution color display (108x65mm), 800x480 pixels, and 24-bit color.
• The nal PA stage uses a rugged LDMOS transistor - BLF188XR.
• Compatible with all transceiver models available on the market - does not need any special
signals: „ground on transmit“ and less than 50W of RF drive power is sufcient.
• 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 1200S is extremely simplied: the screen menus are intuitive
and easy to follow, no special skill is required from the operator when changing frequency
bands.
