Acom 1000 HF Amplifier 160-6m

The load plate is a real indicator of resistance and is a powerful tuning aid that, together with the attenuator Automatically controlled input, helps the operator to match quickly and precise the antennas (5-10 seconds typically). The self-operation function (if enabled), keeps the amplifier in running mode, thus saving money time and manual operations.

No tuner of antenna

The amplifier can perform the functions of a tuner of antenna for VSWR up to 3:1, thus allowing you to quickly change antenna and to use over a wider frequency range (saves setup time point).

Easy to use : One amplifier which is both easy to use, and which takes care of itself. It was designed to last safely up to 300W reflected power, up to 100 milliseconds duration hard tips, RF drive "tails" after a PTT release or, inadvertent setup errors of the operator etc. And it would also not cease to work with a "soft" AC line and it would provide more than half power at only 75% of the rated mains voltage. Withstands up to 10 milliseconds (down to zero) voltage drops, and up to +15% line voltage spikes - especially important if used on field days, DXpedition, etc.

LCD display

Text messages, 12 parameters, and small-reading tapes of the PEP meter displayed on a dot matrix, backlit LCD. indicators LEDs are provided for RUN, dimmer-on, and ON/OFF conditions.

Ease of maintenance : Signatures of the amplifier's internal status are stored in a non-volatile memory for 7 most recent automatic protection trips. This information is used for diagnostics.

Virtually silent ASK

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

Band input matching wide : With resulting in very good load to the transceiver over the entire 1.8-54MHz spectrum.

4CX800A single (GU74B)

High performance ceramic-metal tetrode Svetlana with 800W dissipation plate is used (forced air cooling, driven on the grid).

Pipe protection : Monitoring permanent and protection of plate and grid voltages and currents, as well as temperature of exhaust.
