    Hello Mikito Nagata，

    Thanks for writing in.

    The relay function on this item is for overcurrent, overvoltage and undervoltage protection. It doesn’t have  relation with AH value, so it can’t control output  according to battery capacity.

    You may try to set overvoltage protection to achieve that goal.

    Best regards.

    in reply to: DROK 180050 voltage reegulator #35248

    Hello,
    Thanks for writing in.
    Do you mean it can work well with other load except charging battery? Could you please tell us how large the input voltage/current is to 180050 when output is set as 13.7V? And is it possible to check the actual battery charging current?
    Best regards.

    in reply to: 1500w booster question / problem #35243

    Hello Joe papa,

    Thanks for writing in.

    We think it should be 2001709014 

    Would you please tell us how large  input current and output current you set?  This may caused by input underpower. And the larger the voltage difference is between input and output, the lower conversion efficiency is.

    To check if it is that case, you can try to increase input voltage to reduce voltage difference.

    Best regards

    in reply to: YB4835VA voltage and amperage digital display: fractional amps #35240

    Hello philip A,

    Thanks for your message.

    As per your description, we think it should be 200069. This version is 200A, we are sorry the resolution is 1V,1A, which is included in product description.

    Only 200068 is with 0.1A solution.

    Best regards.

    in reply to: Adjustments not working #35236

    Hello Jon Wendinger

    Thanks for writing in.

    Do you mean you can’t adjust voltage or current? If it is voltage, please turn CV pot potentiometer anticlockwise for over 20 circles.

    If there is other problem, please kindly tell us more details so that we can check for you. For example, input voltage, output you want to set.

    Best regards.

    in reply to: DROK 0.39" Current Voltage Tester, DC 4.5-100V Digital Multimeter; 0-50A Volt am #35218

    Hello Michael Biagioni,

    Thanks for your message.

    The meter you mean should be 200075. This is 50A version, you need to connect external shunt. Only 20A one doesn’t need shunt.

    Please kindly notice  the current input signal to meter can be only from  tested device negative.

    Best regards

    Hello Matt,

    Thanks for writing in.

    If you select fixed output voltage by soldering the pot on the board，it doesn’t matter how the potentiometer is.

    Best regards.
