Remotely controlled by RS232 interface.
Takes care of itself during operation due to the continuously working protection circuits in all modes.
The operator can monitor digitally more than 10 parameters concerning the working regime of the
amplifier.
Easy maintenance – detailed data (55 parameters) about each of the last 28 hard-fault protection trips
is stored in the amplifier’s nonvolatile memory.
Convenient for expeditions and field operation: extremely compact and light construction, extended
mains voltage range (85-132VAC and 170-265VAC through changing only the main fuses - no
internal switching), limited inrush current and purely sinusoidal consumed mains current, automatic
Power Factor Correction (PFC) – all significant parameters in operation from unstable mains,
generators etc. features achieved thanks to the built-in switching-mode power supply (SMPS).
Perfect electromagnetic compatibility (EMC) both with the highly sensitive as well as with the powerful
appliances in the radio station (receivers, computers, more amplifiers) exceeding the standard EMC
requirements due to the use of PFC and the built-in additional radio-frequency filters.
1-5. Safety considerations, explicit definitions
The linear amplifier ACOM 600S is apparatus Class I of 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 600S amplifier is designed to meet international safety standards and complies with CE safety
and electromagnetic compatibility requirements, as well as FCC regulations.
This operating manual contains an assortment of precautions, indications for cautions, and warnings that
MUST BE FOLLOWED by the user to ensure safe operation and always maintain the ACOM 600S amplifier 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, fire hazard or 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 600S amplifier.
N O T E notes call attention to a procedure which, if not correctly performed, could result in
inconvenience.
W A R N I N G HIGH VOLTAGE!
The mains power voltage plus a high DC voltage up to 500V inside
the ACOM 600S amplifier are LETHAL! For your safety, pull the
amplifier power plug out of the mains wall outlet and WAIT AT
LEAST three minutes EACH TIME BEFORE you remove the cover
of the amplifier.
W A R N I N G HIGH VOLTAGE!
NEVER ALLOW, ESPECIALLY CHILDREN, to push anything into
holes in the case - this will cause ELECTRIC SHOCK! Never touch
an antenna or antenna isolators during transmission or tuning -
this may result in an electric shock or burn. Never expose the
amplifier to rain, snow or any liquids. Avoid placing the amplifier in
excessively dusty environments or in direct sunlight. DO NOT
OBSTRUCT COOLING AIR movement areas.
