Additional Information

ACOM 1200S Solid State HF + 6 Meter Amplifiers

ACOM 1200S Solid State HF + 6 Meter Amplifiers cover the amateur bands from 1.8 through 54MHz. They provide 1000W output power (PEP or continuous carrier) with less than 50W of drive on 240VAC (max. 500W out on 25W RF input on 120VAC). All operational conditions are visible on a multi-function high-resolution color display.

Features include:

• Five-inch (5 in.) (108x65mm) high resolution color display, 800x480 pixels and 24-bit color
• Final stage uses rugged LDMOS transistor - BLF188XR or equivalent.
• Compatible with all transceiver models available on the market - does not need any special signals: "ground on transmit" (PTT out) and typically less than 50W of RF drive power is sufficient for full power on 240VAC; a maximum of 25W input on 120VAC.
• Broadband input circuit provides a perfect transceiver load with SWR below 1.2:1 (typically 1.1:1), with no amplifier tuning, throughout the frequency range 1.8 to 54MHz
• The overall operation of ACOM 1200S is extremely simplified: the screen menus are intuitive and easy to follow
• Optional automatic control – when connected to a transceiver with a CAT interface, the amplifier monitors constantly, follows the operating frequency, and changes the bands accordingly
• If NOT CONNECTED with CAT interface, the amplifier monitors the RF input with a built-in frequency counter and automatically switches bands
• Remotely controlled by RS232 interface
• Protects itself during operation due to continuous protection circuits in all modes
• The user can monitor more than 10 parameters
• Easy maintenance – detailed data (55 parameters) about each of the last 28 protection trips is stored in the amplifier's nonvolatile memory
• Convenient field operation: extremely compact and lightweight construction, extended mains voltage range (93V to 265V), limited inrush current and Power Factor Correction (PFC) – all significant parameters in operation from unstable mains, generators etc. features achieved thanks to the built-in switching mode power supply (SMPS)
