    Series and Parallel Connections
    Hi Team,
    Can the output of the multiple booster be connected in series (to increase voltage) or in parallel (to increase watts)...?

    Questions about DC to DC boost converters
    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?

    ATO Responded
    Please drop down the page, you would 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.
    Good price and good value DC-DC converter
    Lots of DC-DC converters for sale on So I just found the one the best met what I was needing and took the chance. Well this unit works as advertised. No issues at all. Good price and good value.
