About ACOM 700S - 700W HF+6m Amplifier

Acom A-700S is a compact, fully featured top quality 700 w solid state linear amplifier ( for 27w input) , covers from 1,8-54 MHz, (Including 5 MHz Amateur Band).


  • High resolution colour display, 800x480 pixels, and 24-bits colours.
  • Final stage uses field effect (MOSFET) transistors type MRFE6VP6300H, designed to withstand high mismatch (SWR) at the output and are intended for operation in aerospace, industrial, mobile, and radio broadcast applications.
  • Compatible with all transceiver models available on the market - does not need any special signals:
  • "ground on transmit" (PTT) and 30W of RF drive power is sufficient.
  • Broadband input circuit providing a perfect transceiver load with SWR below 1.2:1 (typically 1.1:1)
  • Simple operation: the screen menus are intuitive and easy to follow.
  • Automatic control when connected to a transceiver with a CAT interface, follows the operating frequency, and changes the bands accordingly.
  • Even if not connected with CAT interface, the amplifier monitors the frequency of the input signal through the built-in frequency counter and automatically switches over the bands.
  • Remotely controlled by RS232 interface.
  • Takes care of itself during operation due to the continuously working protection circuits in all modes.
  • The operator can monitor digitally more than 10 parameters concerning the working regime of the amplifier.
  • Easy maintenance - detailed data (55 parameters) about each of the last 28 hard-fault protection trips is stored in the amplifier's nonvolatile memory.
  • Convenient for expeditions and field operation: extremely compact and light construction, extended mains voltage range (85-132VAC and 170-265VAC through changing only the main fuses - no internal switching), limited inrush current and purely sinusoidal consumed mains current, automatic.
  • 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).
  • Perfect electromagnetic compatibility (EMC) both with the highly sensitive as well as with the powerful appliances in the radio station (receivers, computers, more amplifiers) exceeding the standard EMC requirements due to the use of PFC and the built-in additional radio-frequency filters.

We aim to dispatch all parcels within 24hrs. We are normally able to dispatch parcels SAME DAY where orders are received before 2.00pm Monday to Friday.


Whilst we try our best to ship same day, we cannot guarantee delivery time. You will however receive tracking details as soon as your order has been processed.


Please note that we do not process orders over the weekend, so orders placed after 2pm on Friday will not ship until Monday.


Please allow an extra processing day for international orders to enable us to complete export/import custom clearance declarations.
