The ACOM 2020S (A2020S) is a state-of-the art 1500W heavy-duty, solid-state linear amplifier, covering all amateur bands from 1.8 to 54 MHz. It features a Remote Control Unit with the operating information shown on a multi-functional, high resolution colour touch screen. All indicators and controls (except the primary mains switch and power indicator) are accessible via the touch screen RCU. All command inputs to the RCU are menu-driven. As standard, the ACOM 2020S is equipped with Ethernet interface facilitating its usage in remotely operated stations.
Easy to operate
The overall operation of ACOM 2020S is extremely simplified: the touch screen menus are intuitive and easy to follow, and 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 colour display with Touch screen
Amplifier status indications are explained via detailed text displayed on the RCU 7″ high-resolution colour touch display (155×90 mm, 1024×600 pixels, and 24-bit colour).
Compatible with all transceiver models – does not need any special signals: “ground on transmit” and RF drive power is sufficient.
Two power modules
Employs two powerful pa modules with power splitting/combiner
LDMOS transistor technology
The two final PA stages each use the rugged LDMOS transistor – MRFX1K80HR5 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.
Takes 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.
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 via the Internet through integrated Web interface and built-in Ethernet RJ45 port and Wi-Fi adapter.
Compact and lightweight construction
Extremely compact and lightweight construction with built-in switching-mode power supply (SMPS) that operates with an extended mains voltage range of 200-240 VAC, ±10% (180-264 VAC limiting values). The consumed current is purely sinusoidal, Power Factor Corrected (PFC) and inrush current limited. This makes the operation of unstable mains and generators easy and trouble free.
Complies 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.
