Acom 500S Solid-State 160-4 m Linear Amplifier

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

11.7 dB ±1.5 dB (typically 35 W drive for rated output);
Mains Power Supply Voltage

100-240 VAC ±10%, 50-60 Hz, Single phase;
Mains Power Consumption at Rated Output Power

Up to 1000 VA;
Power factor at rated output: 0.95 or higher;
Mains Power Consumption in Low Energy (Waiting) Mode

Less than 1 VA;
