U20533 Used ACOM 1200S Solid-State 1.8-54 MHz Linear Amplifier 1000W

U20533 Used ACOM 1200S Solid-State 1.8-54 MHz Linear Amplifier 1000W

This pre-owned ACOM 1200S solid-state linear amplifier is in great overall condition, showing only light handling nicks along the metal cabinet and minor scuffs along the bottom edge of the front faceplate from normal shack positioning. The front mesh intake grille, push-buttons, rocker power switch, and high-resolution color display screen are clean and well preserved. On the rear panel, the RF input and output SO-239 jacks, RCA keying connectors, D-sub communication ports (CAT/AUX, RS-232), ground terminal, and IEC power inlet are pristine with clean contacts and bright plating. It comes complete with a heavy-duty grounded AC power cord, packed in it's original factory box. 

The ACOM 1200S is a state-of-the-art, fully automatic solid-state linear power amplifier covering all amateur bands from 1.8 through 54 MHz (160 meters through 6 meters). Engineered around a rugged, high-durability LDMOS power transistor, it delivers 1000 Watts PEP or continuous carrier output across all modes (SSB, CW, RTTY, and digital modes like FT8) with low drive requirements (typically 50W or less). It features an intuitive, high-resolution color TFT display that provides real-time forward and reflected power, SWR, operating frequency, and comprehensive system telemetry. Designed for seamless station integration, the 1200S includes automatic frequency tracking via an internal RF frequency counter or transceiver CAT interface, robust protection circuitry against high SWR, overdrive, and thermal overload, whisper-quiet proportional cooling, and wide-range auto-switching AC mains operation (93–265V AC).

Condition

• Cosmetic Condition: Great pre-owned condition overall. Exhibits light handling nicks along the painted cabinet edges and surface scuffing along the lower front faceplate bezel.

• Front Panel & Display: The color TFT display lens is clear and readable, and the front-panel control buttons and main power switch actuate crisply.

• Rear Connectors & Chassis: The SO-239 RF input/output ports, Key In/Out jacks, grounding stud, RS-232/CAT ports, and fused AC receptacle are in excellent condition.

• Power Cable: Includes a heavy-duty 3-prong grounded AC power cable.

Key Features

• 1000W Continuous RF Output: Delivers a full 1000 Watts PEP or carrier power on all amateur bands from 160M to 6M (1.8–54 MHz) across all operating modes.

• Advanced LDMOS Technology: Utilizes a rugged LDMOS final amplifier transistor engineered for high linearity, efficiency, and high SWR tolerance.

• Full-Color TFT Display: High-resolution screen displays forward power, reflected power, SWR, operational status messages, and comprehensive menu options.

• Fast Band Switching: Features automatic frequency tracking via internal RF frequency counter or direct CAT interfacing with popular modern transceivers.

• Comprehensive Protection Suite: Monitors forward/reflected power, load impedance, voltages, currents, and temperatures, with automatic fault protection and event logging.

• Whisper-Quiet Cooling: Proportional multi-speed cooling fan system designed for quiet shack operation even during heavy contest duty cycles.

• Universal Power Supply: Built-in switching power supply with active Power Factor Correction (PFC) operating on 93–265V AC automatically.
