Features

1.4.
5" high resolution color display (108x65 mm), 800x480 pixels, and 24-bit color.
•
The ACOM 700S amplifier uses a rugged LDMOS transistor.
•
Compatible with all transceiver models available on the market - does not need any special signals:
•
"ground on transmit" and less than 40 W of RF drive power is sufficient.
Broadband input circuit, providing a perfect transceiver load with SWR below 1.2:1 (typically 1.1:1),
•
without retuning throughout the whole frequency range from 1.8 to 54 MHz.
The overall operation of ACOM 700S is extremely simplified: the screen menus are intuitive and easy
•
to follow, no special skill is required from the operator when changing frequency bands.
Automatic control - when connected to a transceiver with CAT capability, the amplifier will track the
•
operating frequency, and will change bands accordingly.
Even if not CAT connected, the amplifier monitors the input signal frequency through the built-in
•
frequency counter and automatically switches bands.
Remotely controlled by RS-232 port and via Internet by the ACOM eBox Ethernet Remote Control
•
device.
Takes care of itself via continuously working protection circuits in all modes.
•
The operator can monitor numerically more than 10 parameters of the amplifier in operation.
•
Easy maintenance - detailed data (55 parameters) about each of the last 28 hard-fault protection trips
•
is stored in the amplifier's non-volatile memory.
Convenient for expeditions and field operation due to the extremely compact and lightweight
•
construction and the built-in switching-mode power supply (SMPS).
SMPS operates with extended mains voltage range of 100-240 VAC, with no internal switch over. The
•
consumed current is purely sinusoidal, Power Factor Corrected (PFC) and inrush limited. This makes
the operation from unstable mains and generators easy and trouble-free.
Perfect electromagnetic compatibility (EMC) with both highly sensitive devices and the powerful
•
devices in the radio station (receivers, computers, other amplifiers) exceeding the standard EMC
requirements due to the used PFC and built-in radio-frequency filters.
