    Product Features:


    1: Module : 15A synchronous-rectified buck
    2: Module Properties: non-isolated step-down module (BUCK)
    3: Input voltage: DC4-32V (Limit 36V)
    4: Output voltage: DC1.2-32V continuously adjustable
    5: Minimum differential pressure input and output: 1V
    6: Output current :0-15A 10A long natural cooling, the temperature does not exceed 60 degrees, the peak of up to 20A. Decrease the amount of higher ambient temperatures use.
    7: Operating temperature: -40 to +85 ℃
    8: Operating Frequency: 150KHz
    9: Conversion efficiency: Up to 98% (efficiency and input and output voltage, current, pressure related)
    10: Short circuit protection: Yes (limit current 25A) input fuse is 15A
    11: Over-temperature protection: Yes (over-temperature automatically reduce the output current)
    Input Reverse Polarity Protection: None (if required in the input string into the diode)
    Installation: four 3mm screws
    12: Connection: terminals, solderless, V-IN as an input, V-OUT is an output
    13: Module dimensions: length 60mm width 51mm height 22mm
    Please note: recommendation：working under 10A would be better. if want it work with 10-15A for long time,please add the fan for cooling.

    14: Application: it's useful accessories to DIY LED Panel light, please take a look how to use this Step Down Buck Converter to DIY your led panel light with our led strip light in "DIY Perks" Video
