ACOM 1400S

Usage
The ACOM 1400S is a state-of-the-art linear power amplifier that covers all amateur bands from 1.8 through 54 MHz and provides 1200 W output power (PEP or continuous carrier). The amplifier operating information is shown on a separate Remote Control Unit (RCU) equipped with a touch screen.

Easy to operate
The overall operation of ACOM 1400S is extremely simplified: the touch screen menus on the RCU 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 color touch display
Amplifier status indications are explained via detailed text displayed on the RCU 7" high resolution color touch display. 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.

Transceiver-independent
Compatible with all transceiver models - does not need any special signals: "ground on transmit" and less than 50 W of RF drive power is sufficient.

Remote control capabilities
Remotely controlled via the Internet through an integrated Web interface and an Ethernet LAN (RJ45) port, located on the RCU rear panel.

LDMOS transistor technology
The final PA stage uses a rugged 65 V LDMOS transistor for heavy operation modes.

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.

Intelligence
Takes care of itself during operation via continuously working protection circuits in all modes. The operator can monitor many parameters of the amplifier in operation.

Easy maintenance
Detailed data (55 parameters) about each of the last 28 hard-fault protection trips is stored in the amplifier's memory.

​Compact construction
Extremely compact construction with built-in switching-mode power supply (SMPS) that operates with an extended mains voltage range of 90-264 VAC, 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.

Electromagnetic compatibility
Perfect electromagnetic compatibility (EMC) with both highly sensitive devices and the powerful devices in the radio station (receivers, computers, other amplifiers) exceeding the standard EMC requirements due to the used PFC and built-in radio-frequency filters.
