    in reply to: Board ok to charge batteries? #35959

    Hello John，

    Thanks for writing in.

    Is it this item? 180080

    This item doesn’t have current feedback protection. For charging battery, it is better to add diode at output side.

    Best regards.

    in reply to: DROK 600W 12A Dc Boost Voltage Converter Modification help #35923

    Hello  Mike Hunter,

    Did you  remove the CC potentiometer? You can  just set the output current as 3 amps.  The output current will not be over 3 amps in that case.  That should not have influence on your application.

    As we don’t get schematic from factory, we are sorry we are unable to show it. Hope you can understand.

    Any more questions, please kindly let us know.

    Best regards.

    Hello David,

    Thanks for your order.

    12mm diameter  is too large.We are sorry so far we don’t have timer can hold that cable.

    Could you please kindly check how large the load current will be? This item can control load within DC 30V 10A.

    About your last questions, do you mean connect the thick wire and thin wire in series?

    Best regards.

    in reply to: Power factor #35893

    Hello Tony Jones,

    Thanks for writing in.

    This meter only  measure active power.   If  load is not pure resistive,  powe factor is not closed to 1.  So  P< U*I .

    If possible, is it convenient for you to confirm  the power factor for your device?

    Any more questions, please kindly contact us.

    Best regards.
