3x2000 photodivider combiner

FEATURES:

The ACOM3x2000A is a HF power splitter / combiner which is a passive device designed to sum the outputs of three HF linear amplifiers into a common load while the amplifiers are driven by a single exciter. There is no difference from the operation of a three times more powerful single amplifier. 

For proper operation, the combiner requires three amplifier outputs having equal amplitudes and phases, i.e. three coherent signals. This is achieved by the use of three identical amplifiers in the three channels. For best results we recommend three automatic amplifiers of the type ACOM2000A. Manual tune amplifiers with a precise tuning indicator like ACOM1200, ACOM1000, ACOM1010 or ACOM1011 can be used too. All these models use a broadband input network which sets minimum phase differences between the units.

An automatic protection circuit is implemented in the ACOM3x2000A, which  monitors the three amplifier outputs during operation.  In case of an imbalance, the protection trips thus cutting the drive to the amplifiers and switching the transceiver output to an internal 50 Ohm dummy load. The imbalance power, both input and output, is swamped by powerful resistors until the protection trips.  Therefore the transceiver and the three amplifiers are well protected.  After fixing the trouble  you can resume operation by pressing the button RESET.

FEATURES:

Easy operation.
The plate-load True Resistance Indicator (TRI) is an ACOM innovation that provides quick and precise tuning, typically in less than 10 seconds. The auto-operate function will return the amplifier to the OPERATE mode automatically after each protection trip, saving time and avoiding manual switching.

No tuner needed.
No external antenna tuner is required as long as the antenna VSWR is 3:1 or lower. The amplifier will perform the functions of an antenna tuner, enabling you to change antennas faster and use them over wide frequency ranges.

A durable amplifier.
This amplifier is both user-friendly and self-monitoring. It is designed to safely withstand up to 240 W of reflected power, up to 100 milliseconds of drive spikes (RF “tails” after a PTT or KEY release), and even operator tuning errors. It is also capable of operating at more than half its designed output power at only 75% of nominal line (mains) voltage. Because it can tolerate deep voltage drops (down to zero for 10 milliseconds) and 15% line voltage spikes, it is particularly suited for use in portable environments, such as field days and DXpeditions.

LED bar-graph display.
The upper LED bar-graph always reads peak forward power while the lower LED bar-graph is for the reflected power. LED warning indicators are provided for abnormal conditions of grid 1, grid 2, and plate parameters.

Antenna selection.
Two antenna outputs are selectable on the front panel of the amplifier.

Efficient tuning.
Antenna matching can be achieved in less than 10 seconds and at a quarter of nominal output power, which produces lower risk of interference to other stations and greater safety to the amplifier components.

Transceiver-independent.
The amplifier operates without special signaling from the transceiver; it needs only “ground on TX” and 60 W RF drive power to operate at full output power.

Input matching.
Broadband input matching circuitry offers excellent loading characteristics for the driving transceiver, from 1.8MHz to 30MHz.

Single tube operation.
A single Svetlana 4CX800A (GU74B) high-performance ceramic-metal tetrode with plate dissipation of 800W (forced air cooling, grid-driven) is used for maximum efficiency.

Permanent monitoring and protection 
of the plate and grids currents.

The Bias Optimizer minimizes heat dissipated by the tube, assuring tube longevity.

High voltage protection.
Design of the high-voltage power supply eliminates the danger of turn-on transients affecting sensitive devices connected to the same line (mains) circuit. Moreover, the amplifier can be configured to accommodate any of 8 nominal line voltages between 100 and 240 V, 50 or 60 Hz.

Band inclusion.
The amplifier can be shipped with 10 and 12-meter capability disabled as required by the Federal Communications Commission (FCC), for United States users. Contact your dealer about enabling those bands.

FEATURES

The ACOM 1000 HF Linear Amplifier is the world's best value in an amateur HF amplifier. The ACOM 1000 gives you a comfortable 1000 watts output on all amateur bands from 160 through 6 meters.
 
Easy to operate

The plate-load True Resistance Indicator (TRI) is a powerful tuning aid which, together with the automatically controlled input attenuator, helps the operator to quickly and precisely match antennas (5-10 seconds typically). The auto-operate function (when enabled) maintains the amplifier in OPERATE mode for you, thus saving manual operations and time.


No antenna tuners

The amplifier will perform the functions of an antenna tuner for VSWR up to 3:1, thus enabling you change antennas faster and use them over a wider frequency range (saving tuning time).

User-friendly

An amplifier that is both user-friendly, and that looks after itself. It is designed to safely withstand up to 300W reflected power, up to 100 milliseconds duration of drive spikes, drive RF "tails" after a PTT or KEY release, operator's inadvertent tuning errors etc. It would also not cease to function with a "soft" AC line and would deliver more than half power at only 75% of nominal mains voltage. Withstands up to 10 milliseconds (down to zero) voltage drops, and up to +15% line voltage spikes - important particularly when used at field days, Dxpeditions, etc.

LCD comment display

Text messages,12 parameters, and strip peak-reading PEP meter displayed on a dot-matrix, back-lighted LCD. LED indicators are provided for OPERATE, attenuator-on, and ON/OFF conditions.

Easy maintenance

Signatures of the amplifier internal status are stored in a nonvolatile memory for 7 most recent auto protection trips. This information is used for diagnostics.

Virtually silent QSK

The input bypassing and the vacuum antenna relays are very quiet even in CW mode due to their special mounting.

Broadband input matching

Resulting in very good load to the transceiver over the entire spectrum 1.8-54MHz.

Single 4CX800A (GU74B)

A Svetlana high performance ceramic-metal tetrode with plate dissipation of 800W is employed (forced air cooling, grid-driven).

Tube protection

Permanent monitoring and protection of plate and grid voltages and currents, as well as of the exhaust temperature.
