    Description

    DESCRIPTION
    This board is intended to control any kind of solid state amplifier. The board based on modern STM8S CPU and 16x2 LCD.
    All PA parameters will be under strict and constant control of this board.
    Board can control and display:
    - Temperature, up to 4  DS18B20 MAXIM digital thermometers,  1 mechanical sensor as final level of protection
    - Power supply voltage, 100v max
    -
    Power supply c
    urrent, ACS756 IC as current sensor, 50A max
    - SWR and Output RF power from external sensor, 2000W max.
    - Input RF power from external sensor, 99w max.
    - PTT in, GND active
    The board has 8  digital
    output lines
    ("open drain", 50v/250ma max)  to control:
    - Amplifier bypass relay
    - Amplifier power on/off
    - PWM output for FAN control, 500 Hz, width depends on temperature from DS18B20 sensors
    - PTT output, delayed
    - Error LED
    - Binary band code (4 bits)
    Board has many
    levels  of
    protection in multiple area  of PA
    - Temperature protection, 2 levels, soft level can be set via software settings menu
    - Overvoltage
    protection,
    value can be set via software settings menu
    - Overcurrent protection
    ,
    value can be set via software settings menu
    - Excess of output RF power
    protection
    ,
    value can be set via software settings menu
    - Excess of input RF power
    protection
    ,
    value can be set via software settings menu
    - SWR
    protection,
    value can be set via software settings menu
    All
    settings are
    stored in EEPROM, and once set - they will always work.
    PA bypass relay and
    PTT
    output switching is under sequencer control.
    Sequencer delays can be adjusted (from 0ms to 100ms, 1ms step) and stored via software settings menu.
    Board size is 125mm x 100mm.
    Every buyer will get schematic, wiring diagrams and software description.
    Every buyer will also get FREE future software updates.
