    in reply to: Output voltage on 200150 boost converter drops as soon as I connect a load #62098

    Hello Blake Ward，

    Could you please tell us wheter it is in constant current now?

    Constant voltage and constant current can’t work in the meantime. When current regulator is enable, voltage regulator compoent is disable.  Only one mode is enable each time.  In general, we charge battery in constant current mode firstly, when battery voltage reaches preset charing voltage, it will enter constant voltage mode.

    For any more questins, please let us know.

    Best regards.

    in reply to: Drox 300043 malfunction? #61348

    Hello ，

    Is the output voltage 10v when no device is connected?

    If voltage is over 5.6v, decimal point will flicker. Is your like this?

    in reply to: Current not working for meter 200139. How to wire for recreation vehicle? #61260

    Hello Tim J,

    The connection for 200139 is different from usual meter. Please check below diagram, each two ports are shorted. So power supply is connected to the middle, load is connected to the top and bottom ports. Please check if that is available for your application.

    in reply to: Calibrating #61252

    Hello,

    We  are sorry we can’t check problem from this picture. Actually, we hope to check how it works by video.

    Here are few questions:

    1. If the direction of  load current follows the arrow on current transformer, it should be positive current.  However it is negative current. Would you like to draw a simple diagram to show your connection?

    2.You mentioned AH goes to 0 when charger is connected. How it is before connecting charger, can it show AH?

    3.  Did you set the BPC parameter  successfully? If the right side is not the same as the left side, actually setting is not successfully.

     

    4. Did you try check current with other meter? Is it is 0 A?
