Product Features

This is a Buck-Boost DC/DC Converter. Buck-boost means that the unit will allow the DC input voltage to be higher or lower than the output voltage, which lets you use 12 volt DC LEDs on a boat or vehicle, where the charging circuitry ordinarily exceeds 12 volts and would otherwise damage your LEDs. Limits DC voltage to no more than 12 Volts.
  • 8 amp (100 watt) maximum.
  • Converter will boost a voltage as low as 10.5 volts to 12 volts and buck (limit) up to 30 VDC at 12 VDC, a stable output that will protect your LEDs and controllers.
  • Output voltage adjustment from 11 - 13.9 volts by internal potentiometer VR2, near C2.
  • Peak output power of 120 watts (case gets to 60°C at 120 Watts continuous, external cooling can extend).
  • No-load overhead < 100 mA.
  • Line regulation: 1%.
  • Load regulation: 3%.
  • Efficiency >75%.
  • Temperature range: 0-55°C = 32-130°F.
  • Protection:
    1. Input polarity protection;
    2. Input low voltage drop out [power off reset;]
    3. Input high voltage protection [power off reset;]
    4. Output short circuit protection [auto reset;]
    5. Output current limit [auto resume;]
    6. Over temperature protection [power off reset.]
Do not use a dimmer on the primary side.

Running motors from this unit will void the 1-year manufacturer warranty.


Use to protect 12 volt DC LED systems on vehicles, solar systems or other off-grid systems, in which the charging system may drive the voltage over 12 volts DC.
