Description

Usage
The ACOM 500S is a state-of-the art linear power amplifier that covers all amateur bands from 1.8 through 70.5 MHz and provides 500 W rated output power (PEP or digital). The amplifier operating information is shown on a multi-functional, high-resolution color display. ACOM 500S can be controlled either by the six front-panel buttons or remotely.

Easy to operate
The overall operation of ACOM 500S is extremely simplified: the screen menus are intuitive and easy to follow, and no special skill is required from the operator when changing frequency bands.

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 color display
All amplifier status indications are explained via detailed text displayed on the 5″ high-resolution color display (108×65 mm, 800×480 pixels, and 24-bit color).

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 500S amplifier uses a rugged LDMOS transistor.

Broadband input circuit
Broadband input circuit, providing transceiver load with SWR below 1.5 without retuning throughout the whole frequency range from 1.8 to 70.5 MHz.

Intelligence
Takes care of itself via continuously working protection circuits in all modes.

Remote control capabilities
Remotely controlled by RS-232 port and via the Internet by the ACOM eBox Ethernet Remote Control device.

Easy maintenance
Detailed data about each of the last hard-fault protection trips is stored in the amplifier’s non-volatile memory.

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.

Frequency Coverage

  • All amateur bands from 1.8 through 70.5 MHz;
  • Extensions and/or changes on request;

Rated Output Power

  • 500 W ±0.5 dB, PEP or digital;

Intermodulation Distortion (IMD3)

  • Better than 30 dB below rated PEP;

Harmonic and Parasitic Emissions Output Suppression

  • Below 30 MHz – better than 50 dBc below rated output;
  • Above 30 MHz – better than 70 dBc below rated output;

Input Impedances

  • Nominal value: 50 Ohm unbalanced, UHF (SO-239A) type connectors;
  • SWR: Below 1.5 (1.2 typically), 1.8-70.5 MHz continuous range;
  • RF bypass: SWR – below 1.1, 1.8-70.5 MHz;

Antenna Impedance

  • Nominal value: 50 Ohm unbalanced;
  • Two antenna outputs available:
    • RF OUTPUT 1 output has to be used for direct connection to ACOM antenna tuners 04AT or 06AT only. ACOM antenna tuners 04AT and 06AT support antennas within 160 to 6 meter bands;
    • RF OUTPUT 2 output has to be used for direct connection to antenna or to non‑ACOM antenna tuner. A well-matched antenna with an SWR below 1.5 can be connected to this output for any band. While low SWR is good for any band, it is extremely important on 6 and 4 m;
  • Antenna connectors: PTFE UHF (SO-239A) type;

RF Power Gain
