Acom 700s linear amplifier 700 watts hf plus 50mhz
5-inch (5") (108x65mm) high-resolution color display( 800x480 pixels, and 24-bit colors).
The final phase uses MRFE6VP61K25N field effect transistors (MOSFET), designed to withstand a high discrepancy (SWR) output and intended for operation in aerospace, industrial, mobile and broadcasting applications.
The final PA stage uses a robust LDMOS transistor - MRFE6VP61K25N or equivalent.
Compatible with all available transceiver models on the market - it does not require special signals: it is enough "ground on transmission" (PTT) and 40 W of RF drive power.
Broadband input circuit that provides a perfect transceiver load with SWR less than 1.2:1 (typically 1.1:1), without retuning over the entire frequency range from 1.8 to 54 MHz
The overall operation of ACOM 700S is extremely simplified: on-screen menus are intuitive and easy to follow, and no special operator expertise is required when changing frequency bands
Automatic control - when connected to a transceiver with a CAT interface, the amplifier constantly monitors, duly follows the operating frequency and changes the bands accordingly.
Although not connected to the CAT interface, the amplifier controls the frequency of the input signal through the built-in frequency counter and automatically switches bands.
Remotely controlled by the RS232 interface.
He takes care of himself during operation thanks to the protection circuits that work continuously in all modes.
The operator can digitally monitor more than 10 parameters regarding the amplifier's operating regime.
Ease of maintenance: Detailed data (55 parameters) on each of the last 28 serious fault protections is stored in the non-volatile memory of the amplifier.
Convenient for shipments and field operations: extremely compact and lightweight construction, extended range of network voltage (100 V th 240 V), limited peak current and purely sine consumption current, automatic factor correction (PFC) - all significant parameters in unstable network operation, generators etc. features achieved thanks to the integrated switching power supply (SMPS).
Perfect electromagnetic compatibility (EMC) with both high sensitivity and powerful radio station devices (receivers, computers, multiple amplifiers) that exceed standard EMC requirements thanks to the use of PFC and additional radio frequency integrated filters.
