ACOM - 700S / (Ca 2 mnd leveringstid)

PRIS PÅ FORESPØRSEL

Usage
The ACOM 700S is a state-of-the art linear power amplifier that covers all amateur bands from
1.8 through 54 MHz and provides 700 W rated output power
(PEP or continuous carrier). The amplifier operating information is shown on a
multi-functional, high resolution color display. ACOM 700S can be controlled either by the six front-panel buttons or remotely.

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
Remotely controlled by RS-232 port and via Internet by the ACOM eBox Ethernet Remote Control device.

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.
