    Existing reviews of DC-DC Buck Converter, 12V/24V to 5V
    High quality DC-DC buck converter
    Hi, I've been looking for a 12V to 48V boost power supply and I think this one will do the trick.
    20A/960W version.
    OK, I was wondering if you had any detailed spec sheets with graphs-input V vs output voltage etc?
    Is the output voltage regulated or dependent on input voltage?

    Please drop down the page, you will find the spec sheet.
    The output voltage is 48V± 1%. When the input voltage is in the range of 10-25V, and if the input voltage is too low, the output voltage will be unstable.
