l
Less noise in the shack: the input bypassing and the vacuum antenna relays are virtually silent even in
QSK CW mode due to their special mounting.
l
Less QRM and improved Electro Magnetic Compatibility during tuning. Antenna matching can be
achieved in less than 10 seconds at a quarter of nominal output power.
l
Operates without special signals from the transceiver - ground on TX and 60W RF drive power
are sufficient.
l
Broadband input matching circuit resulting in very good load to the transceiver over the entire
spectrum from 1.8MHz up to 54MHz.
l
Uses a single 4CX800A (GU74B) Svetlana high-performance ceramic-metal tetrode with plate
dissipation of 800W (forced air cooling, grid-driven).
l
Permanent monitoring and protection of plate and grid voltages and currents, as well as of the
exhaust air temperature. The Bias Optimizer decreases the heat dissipated from the tube, and there is
automatic protection against overheating in accordance with the specifications of the tube producer.
l
An output RF Arc protection is employed. It safeguards the amplifier, antenna, antenna selector, and
tuner against severe damage in case of possible break down.
l
High voltage power supply inrush current protection, which eliminates the danger of affecting sensitive
devices, connected to the same mains circuit (important when used portable). The amplifier can be
configured for 5 nominal line voltages: 200, 210, 220, 230, and 240VAC, 50 or 60Hz (100, 110, and
120VAC on request).
l
Continuous measuring and/or selectable monitoring of 12 most important parameters of the amplifier,
exciter and antennas via LCD.
l
The amplifier can be shipped with 10 and 12 meters capability disabled as required by the FCC for
US users. Contact your dealer about enabling those bands.
1-5. Safety Considerations, Explicit Definitions
The ACOM1000 HF+6 meters Linear Amplifier is a Safety Class I unit. The third grounding lead of its
mains cord (which is colored yellow with two green stripes) and the ground stud on the rear panel of
the amplifier, (marked GND) must be connected to the stations grounding system for safe operation.
The 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 information, precautions, indications for cautions and warnings which
must be followed by the user to ensure safe operation and to keep the ACOM1000 in safe operating
condition.
