Description
The ACOM 1200S (A1200S) is a solid state linear power amplifier that covers all amateur bands from 1.8 through 54 MHz and provides 1000 W output power (PEP or continuous carrier) with less than 50 W of drive. The amplifier operating information is shown on a multi-functional, high resolution colour display.
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 colour display
All amplifier status indications are explained via detailed text displayed on the 5″ high-resolution colour display (108×65 mm, 800×480 pixels, and 24-bit colour).
Transceiver-independent
Compatible with all transceiver models available on the market – does not need any special signals: “ground on transmit” and less than 25 W of RF drive power is sufficient.
LDMOS transistor technology
The ACOM 1200S amplifier uses a rugged LDMOS transistor.
Broadband input circuit
Broadband input circuit, providing transceiver load with SWR below 1.2 without retuning throughout the whole frequency range from 1.8 to 54 MHz.
Protected
Takes care of itself via continuously working protection circuits in all modes. Detailed data about each of the last hard-fault protection trips is stored in the amplifier’s non-volatile memory.
Remote control capabilities
Remotely controlled by RS-232 port and via the Internet by the ACOM eBox Ethernet Remote Control device (function in development).
Compact and lightweight construction
Convenient for expeditions and field operation due to the extremely compact and lightweight construction and the built-in switching-mode power supply (SMPS). SMPS operates with extended mains voltage range of 100-240 VAC, with no internal switch over. The consumed current is purely sinusoidal, Power Factor Corrected (PFC) and inrush 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) exceeds the standard EMC requirements due to the use of built-in radio-frequency filters.
Size & Weight (operating, excluding connected cables and opened tilt foot bar)
- WxDxH: 372x418x162 mm, 16 kg (14.7×16.5×6.4 inches, 35.3 lbs.);
Warranty
2 Year Warranty backed up with full factory-backed service and repair in our own workshops here at The DX Shop. No shipping to 3rd parties and long waits. After the warranty period ends units can be sent to us for inspection/quote/repair using OEM factory parts where needed that we source direct from Acom. Peace of mind…
Wideband operation Option
This amplifier as standard will operate on Amateur Bands only. We can optionally open the amp up to Continuous operation for MARS etc use. This requires a hardware modification that can be done before despatch. Please contact us to discuss this further.
