1.3. Product Features

Easy to operate
•
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.
User-friendly 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.
High resolution color display
•
All amplifier status indications are explained via detailed text displayed on the 5" high resolution color
display (108x65 mm, 800x480 pixels, and 24-bit color).
Transceiver-independent
•
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.
LDMOS transistor technology
•
The ACOM 700S amplifier uses a rugged LDMOS transistor.
Broadband input circuit
•
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.
Intelligence
•
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.
Remote control capabilities
•
Controlled remotely via the Internet by the ACOM eBox Ethernet Remote Control device (optional
equipment) and through an RS-232 port.
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.
Compact and lightweight construction
•
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.
Electromagnetic compatibility
•
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.
