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 700S.
ACOM
700S is
a state-of-the art linear amplier, covering the amateur bands from 1.8 to 54MHz with
700W output power
(PEP or continuous carrier)
with less than 40W of drive. The amplifier operating
information is shown on a multi-functional, high resolution color display. ACOM 700S may by controlled
either by the six front panel buttons or remotely – via an RS232 port.
NOTE
ACOM 700S
is designed to work with the ACOM 04AT Remote
Automatic Antenna Tuner. The connection of ACOM04AT will make
accessible the features that are inactive onthe amplier display when
ACOM
700S operates without
ACOM 04AT. The operation of ACOM 700S with ACOM 04AT
is described in the ACOM 04AT Operation Manual.

Owner assistance
If technical or operating assistance is needed, please contact your local dealer rst. In the unlikely
case of you needing further information, you may get in touch with ACOM via: fax (+ 359 2 920 96 56),
telephone [phone]), e-mail ([email protected], [email protected]) or by post (blvd.
Nikola Mushanov 151, 1330 Soa, Bulgaria). Website: www.acom-bg.com.

Equipment supplied and options
The amplier is supplied in a single box including:
-
amplier ACOM 700S;
- power cord;
- this manual with a CE declaration of compliance;
-
four pieces of spare fuses
1-4.
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 40W 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 700S 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.

• Automatic control – when connected to a transceiver with CAT capability, the amplier will track
the operating frequency, and will change bands accordingly.
• Even if not CAT connected, the amplier monitors the input signal frequency through the built-in
frequency counter and automatically switches bands.
• Remotely controlled by RS232 port.
• Takes care of itself during operation via continuously working protection circuits in all modes.
• The operator can monitor more than 10 parameters of the amplier in operation.
• Easy maintenance – detailed data (55 parameters) about each of the last 28 hard-fault protection
trips is stored in the amplier’s memory.
• Convenient for expeditions and eld operation due to the extremely compact and lightweight
construction and the built-in switching-mode power supply (SMPS) that operates with extended
mains voltage range of 93-265VAC, with no internal switch over. The consumed current is
purely sinusoidal, Power Factor Corrected (PFC) andinrush limited. This makes the operation
from unstable mains and generators easy and troublefree.
• Perfect electromagnetic compatibility (EMC) with both highly sensitive devices and the powerful
devices in the radio station (receivers, computers, other ampliers) exceeding the standard
EMC requirements due to the used PFC and built-in radio-frequency lters.

Safety considerations, explicit denitions
The ACOM 700S linear amplier is a Class I apparatus regarding protection against electric shock, i.e.
the third grounding lead of its mains cord (colored yellow with two green stripes) and the grounding stud
on the rear panel, marked GND (Fig. 2-1), must be connected to the grounding system of the shack for
safe operation.
The ACOM 700S amplier is designed to meet international safety standards and complies with the CE
electromagnetic compatibility requirements, as well as the FCC regulations.
This operating manual contains precautions, cautions, and warnings that MUST BE CОMPLIED TO
by the user to ensure safe operation and maintaining of the ACOM 700S amplier in a safe working
condition.
PRECAUTIONS:
The EXPLICIT DEFINITIONS described below apply to this operating manual:
W A R N I N G notes call attention to a procedure which, if not correctly performed,
could result in personal injury or re hazard by electric shock or lightning.
C A U T I O N notes call attention to a procedure which, if not correctly performed, could result
in equipment damage, not only in the ACOM 700S amplier.
N O T E notes call attention to a procedure which, if not correctly performed, could result in
inconvenience.
