ACOM 1000 HF Amplifier
 |
|
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
The ACOM 1000 is user-friendly and it looks after itself. It
is designed to safely withstand up to 500W 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, expeditions,
etc.
LCD Comment Display
Text messages, 12 parameters, and strip peak-reading PEP meter displayed
on a dot-matrix, back-lit 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 the seven most recent auto protection trips. This information is used
for diagnostics.
Virtually Silent QSK
Due to their special mounting, the input bypassing and the vacuum antenna
relays are very quiet even in CW mode.
Broadband Input Matching
This results 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.
