\"\"<\/a><\/p>\n

Easy to operate
\nThe overall operation of ACOM 2020S is extremely simplified: the touch screen menus are intuitive and easy to follow, no special skill is required from the operator when changing frequency bands.<\/p>\n

User-friendly automatic control
\nWhen 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.<\/p>\n

High resolution color display with Touch screen
\nAmplifier status indications are explained via detailed text displayed on the RCU 7″ high resolution color touch display (155×90 mm, 1024×600 pixels, and 24-bit color). All indicators and controls (except the primary mains switch and power indicator) are accessible via the RCU’s touch screen, as well as, all command input to the RCU is menu-driven.<\/p>\n

Transceiver-independent
\nCompatible with all transceiver models – does not need any special signals: “ground on transmit” and RF drive power is sufficient.<\/p>\n

Two power modules
\nEmploys two powerful modules in power splitting\/combining technique.<\/p>\n

LDMOS transistor technology
\nThe two final PA stages use a rugged LDMOS transistor – MRFX1K80HR5<\/strong><\/a> or equivalent.<\/p>\n

Broadband input circuit
\nBroadband 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.<\/p>\n

Intelligence
\nTakes care of itself during operation via continuously working protection circuits in all modes. The operator can monitor 11 (eleven) parameters of the amplifier in operation.<\/p>\n

Easy maintenance
\nDetailed data (55 parameters) about each of the last 28 hard-fault protection trips is stored in the amplifier’s memory.<\/p>\n

Remote control capabilities
\nRemotely controlled via Internet through integrated Web interface and built-in Ethernet RJ45 port and Wi-Fi adapter.<\/p>\n

\u200bCompact and lightweight construction
\nExtremely compact and lightweight construction with built-in switching-mode power supply (SMPS) that operates with extended mains voltage range of 200-240 VAC, \u00b110% (180-264 VAC limiting values), with no internal switch over. The consumed current is purely sinusoidal, Power Factor Corrected (PFC) and inrush current limited. This makes the operation from unstable mains and generators easy and trouble free.<\/p>\n

Electromagnetic compatibility
\nComplies with the CE electromagnetic compatibility (EMC) requirements and FCC regulations. Perfect compatibility with both highly sensitive devices and the powerful devices in the radio station (receivers, computers, other amplifiers) due to the used PFC and built-in radio-frequency filters.<\/p>\n
