• 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.
