The ACOM 2020S is a state-of-the art 1500 W heavy-duty, solid-state linear amplifier, covering all amateur bands from 1.8 to 54 MHz. It features a Remote Control Unit model R05 with the operating information shown on a multi-functional, high resolution color touch screen.

All indicators and controls (except the primary mains switch and power indicator) are accessible via the touch screen RCU, as well as, all command input to the RCU is menu-driven. As standard, the ACOM 2020S is equipped with Ethernet interface facilitating its usage in Remotely Operated Stations.

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.

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.

Amplifier status indications are explained via detailed text displayed on the RCU 7" high-resolution color touch display (155x90 mm, 1024x600 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.

Compatible with all transceiver models - does not need any special signals: "ground on transmit" and RF drive power is sufficient.

Employs two powerful modules in the power splitting/combining technique.

The two final PA stages use a rugged LDMOS transistor.

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.

Remotely controlled via the Internet through integrated Web interface and built-in Ethernet RJ45 port and Wi-Fi adapter.

Extremely compact 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), with no internal switch over. 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.
