    Hi, the max. output of this Waterproof Voltage Regulator is 3A, so if your LEDs is over 3A, it cannot meet your requirement. We are sorry we don’t have such product now.
    Thanks.

    in reply to: Drok lm2596 output v increase issue #1876

    Hi foojook, there are two LED indicators on this converter board, the red LED will light on when you measure input voltage and green LED will light on when you measure output voltage. Could you please connect the multimeter on terminal in parallel, then tell us what’s the reading. Maybe you can upload the photos to http://imgur.com then give us the links.
    You can add an ON/OFF switch for the output directly.
    Any other questions, pls feel free to contact us.
    Regards.

    Dear Robert,

    Are you talking this 600V 100A DC Meter, and when you connect 20v power supply then the capacitors exploded? we are sorry that could you please tell us what’s your wiring circuit, pls send us some photos. If you exchange the yellow and red wires, the capacitors will be exploded.

    You can upload the photo to http://imgur.com, then give us the links.

    Looking forward to your reply.

    Best regards,

    Hi Duane Hoole,
    Sorry that we don’t have such meter. does the AC 100-300V 100A meter can use for your OEM application?
    Thanks!

    in reply to: Drok lm2596 output v increase issue #1866

    Hi Cortland Doan, do you mean that the output current is 8.3 mA?? If the 12V is the input voltage, then what’s your output voltage?

    in reply to: Ammeter for boats #1848

    Hi, thanks for your message. but this meter cannot measure negative current. this Voltmeter Current Meter can meet your requirement.

    Here is the DROK DC Voltmeter Ammeter Dual Display, you can choose the meter according to your requirements.

    Any other questions, don’t hesitate to write back to us.

    Thanks.

    in reply to: wire diagram #1837

    Hi, the 3 wires on the meter is ok, they are just signal wires and without a large current flow. the power of the meter is taken directly from the test circuit, so the red wire should connect to the positive of the auxiliary battery. It’s better if you can send us your hand painted wiring?

    Looking forward to your reply.

    Best regards.

    Reply to Dave Traller:

    So what is the actual current. If the current is too small, the value will be inaccurate.

    And this package has included a 100A shunt. Did you get it now?

    Looking forward to your reply.

    Yes, it is ok. But the place as the below image is better. Because the current between thin red wire is small and more easier to control.

    in reply to: Drok lm2596 output v increase issue #1819

    Hi, Is it the LM2596 Voltage Regulator you purchased? Could you tell us what’s your input voltage and output voltage.

    Please note that this is a step down converter. If you need to increase the voltage, the input voltage must be 1V higher than the output voltage.

    Looking forward to your reply.

    Best regards,
