  • 5v/6v 3A Switch-Mode Ultimate BEC (UBEC):

    posted by djarent

    This small little DC/DC converter solves the power loss/heat problems associated with a resistor or series pass type voltage regulator. My use is to drop a 12V battery on my scooter down to about 4V to light a white LED for use as the headlight. My current plan is to use the DX R2 module (350 mA) for the light. In tests, the R2 gets HOT (even at the 5V Hobbywing output). With no heat sink, it gets hot enough to cut in the thermal cutout (LED flashes). Meanwhile, the Hobbywing unit just barely gets warm! I ended up putting a diode in series with the R2 module and it still gets hot but, not hot enough to cut out (although I'll probably need more heat sinking in the scooter light assembly). The Hobbywing is extremely simple to hook up and has a little red indicator LED for operation. It's small and seems to be well-built.
    Other Thoughts: Probably the easiest way to secure it is with a small clip or clamp. A single hole, drilled through the middle of it so it could be mounted with one screw might be a good design feature.
    Bottomline: To drop some voltage without the heat or power loss, this is a great solution.
  • Very nive 12V power unit

    Nice aluminium case makes it light weight and easy to mount on the wall. The AC input terminals are easy to connect, and the 12 V DC terminals are likewise easy to connect.There is a tuning screw to adjust to very accurate output voltage.
    A nice 12V power unit that I recommend for the funcionallity, the ease of use and the quality, but only for installations where the access to the terminals can be blocked.
