High-resolution 5-inch (5") colour display (108x65 mm), 800x480 pixels and 24-bit colour.
The final stage uses NXP BLF188 field-effect transistors (MOSFETs), designed to withstand a high output mismatch (SWR) and intended for aerospace, industrial, mobile and broadcast applications.
Compatible with all transceiver models on the market - no special signals needed: just "ground on transmit" (PTT) and 50 W of RF drive power.
Broadband input circuit providing a perfect transceiver load with SWR below 1.2:1 (typically 1.1:1), without retuning over the entire 1.8 to 54 MHz frequency range
Overall operation of the ACOM 1200S is extremely simplified: on-screen menus are intuitive and easy to follow and no special skills are required of the operator when changing frequency bands
Automatic control capability - when connected to a transceiver with a CAT interface, the amplifier constantly monitors and follows the operating frequency and changes bands accordingly.
Even when not connected to the CAT interface, the amplifier monitors the input signal frequency through the built-in frequency counter and switches bands automatically.
Remote control via RS232 interface.
It looks after itself during operation thanks to protection circuits that work continuously in all modes.
The operator can digitally monitor more than 10 parameters concerning the amplifier's operating conditions.
Easy maintenance: detailed data (55 parameters) for each of the last 28 protection trips caused by serious faults are stored in the amplifier's non-volatile memory.
Convenient for DXpeditions and field operation: extremely compact and lightweight construction, wide mains voltage range (93 V ÷ 265 V), limited inrush current and purely sinusoidal supply current draw, automatic power factor correction (PFC) - all significant when operating from unstable mains, generators etc. These features are achieved thanks to the built-in switch-mode power supply (SMPS).
Perfect electromagnetic compatibility (EMC) with both highly sensitive and powerful radio station equipment (receivers, computers, other amplifiers), exceeding standard EMC requirements thanks to the use of PFC and additional built-in RF filters.
