Features - Acom 1200S Installation, Operation And Maintenance Manual

Features

1.4.
Easy to operate
•
The overall operation of ACOM 1200S 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 - does not need any special signals: "ground on transmit" and
less than 50 W of RF drive power is sufficient.
LDMOS transistor technology
•
Тhe final PA stage uses a rugged LDMOS transistor - BLF188XR or equivalent.
Broadband input circuit
•
Broadband input circuit, providing a perfect transceiver load with SWR below 1.2 (typically 1.1),
without retuning throughout the whole frequency range from 1.8 to 54 MHz.
Intelligence
•
Takes care of itself during operation via continuously working protection circuits in all modes.
The operator can monitor 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 memory.
Remote control capabilities
•
Remotely controlled by RS-232 port and via Internet by the ACOM eBox Ethernet Remote Control
device.
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) that operates with extended mains
voltage range of 100-240 VAC (output power reduced to about 500 W PEP below 200 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.
