    Hi,

    I got the drok LCD screen step-down voltage module (3A peak). The calibration instructions are not clear, can you please send me the calibration instructions ASAP?

    Thanks,

    I love the DROK X000ZZMU77 buck regulator and meter that I bought 3 more.
    They make a great battery charger when used with any old surplus laptop charger.
    My problemis that one of the units just went blank and does nothing.
    Is there a fuse or something that just locks the unit out?
    At the time it failed I was trying to charge a 12 volt ni-cad battery but I thought the current limit would keep it damaging itself.
    Any advice you can offer would be helpful.

    Have you ever considered making a nice case for this product?
    Brian

    hello I have the DROK® DC-DC Voltage Buck Converter Volt Regulator 5V-30V to 0.8-29V Step-down Transformer Power Module 5A Constant Adjustable LED Dual Display Amp/Volt Ampere Ammeter Voltmeter Current Volt Tester.

    How to put CC or CV on this model? The adjusting of current or voltage is easy (just rotating), but How I now it is set to CC or CV?
    Regards

    BOB

    Hello Bob,
    Thank you for writing in and we are sorry for delayed reply.
    The CC ov CV setting is in terms of your load.
    For example, we can set the output voltage and current as 5V 1A. If your load current is less than 1A, then the model will be in CV. When the load current is larger than 1A, it will be in CC.
    So you need to adjust model on base of the load you connect.
    Hope this can help you.
    Best regards
