V-Infinity's newest line of RoHS-compliant power supplies can take a universal input voltage (85 to 264V ac) and have efficiencies up to 88 percent in the 48V model. The VOF-25 measures 3.54 × 2 × 0.75 inches, while the VOF-45/65 versions are 4 × 2 × 1.28 inches. All units are rated to function at 100 percent load from in 0-50C temperatures. Their outputs range from 3.3-48V along 23 different single output models. They also offer a greater power density than 6W/in3, short circuit, over-current and over-voltage protection. Conductive EMI meets CISPR/FCC class B standards, and it has UL/cUL/TUV/CE/CB safety approvals.
The Space Kid, 11, will be one of the first civilians to have his design manufactured in space by NASA, thanks to the City X Project, which inspires kids to think about new 3D-printed inventions that could be useful for humans living in space.
