ACOM 1400S: The Linear Amplifier That Redefines the Standard!

Technology and power at the highest level. The ACOM 1400S is the linear power amplifier that every radio amateur dreams of having in his station. With a coverage that goes from 1.8 to 54 MHz, this jewel of technology provides an incredible output power of 1200 W (both in PEP mode and continuous carrier). Whether you are operating on the low or high bands, the ACOM 1400S will always guarantee you a truly champion performance.

An Intuitive and Super Powerful Interface

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

Advanced Automatic Control

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

Universal Compatibility and Exceptional Performance

Compatible with any transceiver, the ACOM 1400S does not need special signals. A driving power of less than 50 W is enough 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 wideband circuit, you can operate on all bands from 1.8 to 54 MHz with an SWR of less than 1.2 (typically 1.1), without the need for retuning. A simple set-up and impeccable performance.

LDMOS Technology: Power and Reliability

At the heart of the ACOM 1400S is a 65V 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 face the most demanding conditions without compromise.

Remote Control via Internet

The ACOM 1400S is designed for the modern operator. With the integrated Web interface and the RJ45 Ethernet port, you can control the amplifier even remotely , simply via your computer browser. Remote control via the Internet : a convenience that allows you to manage your station even from a distance, with the same precision that you would have directly on site.

Advanced Security 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 in real time as many as 55 vital parameters , saving in memory up to 28 protection events for future analysis. Total security for your investment.

Compact Design and Superior Performance

Don't let the compact size of the ACOM 1400S fool you! Its robust design integrates a switch mode power supply (SMPS) that supports a mains voltage of 90-264 V AC , without the need for internal switching. This ensures stable operation even in environments with unstable mains or generators. The current consumption is pure sinusoidal , with power factor correction (PFC) , for exceptional efficiency in any situation.

Unmatched 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 the fault protection events are automatically saved in the amplifier memory. With its 28 saved events , the operator can easily diagnose and solve any problems quickly and effectively. Maintenance is simple and stress-free .

ACOM 1400S: A trusted companion on your ham radio adventure.
