    Hello Cesar,

    Would you like to offer product link or SKU number so that we can confirm which item it is?

    And what is the input voltage/current and load current when it blew the fuse?

    Best regards,

    in reply to: DC-DC boost Converter #46722

    Hello Ugochukwu anyoha，

    We are sorry it may be hard to make one with such large output current.

    And most of voltage converters can’t decide how much current the load should draw. They just give a limit on output current. Assume output current can be controlled by  tachometer, that just change current limit value instead of actual load current.

    Best regards.

    Hello ，

    Is it this item?  200206

    We don’t recommend that way. It  is hard to ensure both of output parameters stay same, that  is easy to burn the module.

    Best regards,

    Hello Bryan，

    Do you mean 24 v power supply is connected to current input port? If it is that case, what is connected to VCC and GND?

    We are sorry it is hard to confirm connection. Would you like to show that by images or diagram?

    You can share us link or send pictures to service@droking.

    Best regards,

    DROK
