    Description

    SWR and POWER and Temperature universal digital indicator with dual protection
    .
    Can be used for any amplifier - BI-polar, LDMOS or TUBE.
    SWR bridge not included. It`s only digital meter.
    IMPORTANT:
    BUY THIS, ONLY IF YOU KNOW WHAT TO DO WITH IT.

    Features :
    **NEW** -  Showing "OVERLOAD", if
    SWR ports are overvoltaged
    **NEW** - Additional option for "detector compensation", for use only when needed.
    * Practical mimimum measure - from 0W to 250mW (Divider =1), Maximum 8500W (Divider=185)
    * Can show  SWR value up to 9.99.
    * Option for Power divider - custom user selectable from 1 to 185 - max 8500W
    * Option for SWR divider - custom user selectable from 1 to 15.
    *
    UPDATE
    ! Now option for SWR protection level - custom user selectable from 1.5 to 10 (0.1 increments).
    * from 9 to 12V power supply.
    * Measure temperature from -55 to +125 degrees in 0.1 degree increments.
    * Temperature protection point from 10 to 120 degrees.
    * Temperature difference interval from 0 to 50 degrees.
    * Showing "SWR = NO SIGNAL" when no levels at swr ports.
    * Showing SWR = NO ANTENNA when SWR < 1 (No connected antenna/load or FWD and REF are switched).
    *
    Showing  SWR PROTECT ON! on second row when protection is ON.
    * Showing TEMP PROTECT ON! on second row when this protection is ON
    * Manual turn ON/OFF the backlight of the display (ON by default)
    * Four buttons to control the settings.
    * Jumper pins for resetting both protections - manual or automatic . If automatic way is choosed, user can leave а jumper in place -  NOT recommended (especially for relay based schematic).
    If user wants to manual reset the protection - reset pins can be maked as external "non-hold" button (on the front panel). In this case protection will not reset, until user press the button.
    You can use it with some SPDT reed relay to control  up to 100mW RF signal.
    This type of protection can fully stop the RF signal to the amplifier - manual resetting is the best way to fully protect RF amplifiers from high SWR.
    * Saving values in case of loosing power supply. Last saved values are loaded after power supply is back.
    * Board size - 85x50 mm
    Temperature sensor will be included with the meter with 3 pin female connector, but no cables, because every user will need different length of cables from meter to the sensor. Drawing for right connection of the sensor will be in the instructions.
    Temperature difference is an option where user can set the point of "releasing the temperature protection".
    Example: If Protection point is at 90 degrees and temperature difference is 15 degrees, then Protection will be released when unit is cooled(self cooled) down to 75 degrees.
    Instructions manual is included.
    May require calibration.
    Unit can measure RF power via "direct output method".
    This means that RF power can be measured directly  from the output of the final amplifier.
    Unit can work even with HF directional couplers.
    Can be used with any SWR bridge - external dividers for FWD and REV must match the user selected SWR divider. Max divider is 15 - this means you can induct up to 75V into forward and reverse sides of your SWR bridge.
