ACOM 1400S: The Linear Amplifier Redefining Standards!

Technology and power at the highest level. The ACOM 1400S is the linear power amplifier every radio amateur dreams of having in their station. Covering 1.8 to 54 MHz, this technological marvel provides an incredible output power of 1200 W (in both PEP and continuous carrier modes). Whether you're operating on low bands or higher ones, the ACOM 1400S will always guarantee champion-level performance.

An Intuitive and Super Powerful Interface

The heart of the ACOM 1400S's control is a remote unit (RCU) with a 7-inch color, high-resolution touchscreen display, allowing you to monitor and manage all operational aspects with extreme simplicity. The interface is intuitive and immediate; no advanced skills are needed to operate the amplifier. Band changing? Easy as a touch! Thanks to guided commands, switching from one frequency to another is child's play, even for less experienced users.

Advanced Automatic Control

Imagine an amplifier that adapts to your needs. The ACOM 1400S can automatically monitor the transceiver's frequency, changing the band based on the operating frequency, whether you connect it via CAT or not. If there is no CAT connection, the integrated frequency counter takes over, detecting the signal frequency and automatically adjusting the band. A seamless experience, where your focus remains on communication, not device management.

Universal Compatibility and Exceptional Performance

Compatible with any transceiver, the ACOM 1400S requires no special signals. Just less than 50 W of drive power is needed to get the most out of this amplifier. Its advanced technology is compatible with any radio station, without the need for complex adaptations. And with the broadband circuit, you can operate on all bands from 1.8 to 54 MHz with an SWR below 1.2 (typically 1.1), without the need for retuning. A simple setup and impeccable output.

LDMOS Technology: Power and Reliability

At the heart of the ACOM 1400S, you'll find a 65 V LDMOS transistor, which ensures stable output power even during the most demanding operations. This transistor is designed to withstand the strongest stresses, always maintaining high performance. An alliance of power and reliability that allows you to tackle the most difficult conditions without compromise.

Remote Control via Internet

The ACOM 1400S is designed for the modern operator. With the integrated Web interface and RJ45 Ethernet port, it is possible to control the amplifier remotely, simply via your computer's browser. Remote control via Internet: a convenience that allows you to manage your station even from afar, with the same precision as if you were on site.

Advanced Safety and Protection

The ACOM 1400S is equipped with advanced protection circuits that constantly monitor the amplifier's operation in all operating modes. Its "intelligence" allows you to monitor no less than 55 vital parameters in real time, saving up to 28 protection events in memory for future analysis. Complete security for your investment.

Compact Design and Superior Performance

Don't be fooled by the compact size of the ACOM 1400S! Its robust design integrates a switching mode power supply (SMPS) that supports a mains voltage of 90-264 V AC, with no internal switching required. This ensures stable operation even in environments with unstable networks or generators. The absorbed current is pure sinusoidal, with power factor correction (PFC), for exceptional efficiency in every situation.

Unparalleled Electromagnetic Compatibility

The ACOM 1400S exceeds standard EMC requirements, ensuring perfect electromagnetic compatibility with other devices in your station. You no longer have to worry about interference: integrated RF filters and excellent PFC ensure that the amplifier operates without creating disturbances, even in highly sensitive environments.

Easy and Smart Maintenance

All data related to fault protection events is automatically saved in the amplifier's memory. With its 28 saved events, the operator can easily diagnose and resolve any problems quickly and effectively. Maintenance is simple and stress-free.

ACOM 1400S: A reliable companion in your amateur radio adventure. Whether you are looking for the ultimate in power, reliability, and ease of use, the ACOM 1400S is the amplifier that will take you further. Get ready to push your signals beyond known boundaries, with a tool designed for true radio enthusiasts.
