Product Overview
PowerStick features an above board height of
only 0.35'' and a footprint as small as 2.28''L x
0.5''W. PowerStick converters deliver up to
75 Watts per module and up to 900 Watts in
fault-tolerant arrays.
Vicor’s innovative through-the-board mounting
results in an effective power conversion density
of 188W/in3. A wraparound aluminum body,
available in a variety of options, provides integral
cooling in a broad range of applications and
thermal environments, allowing customers to
achieve peak power density within the 0.35''
low profile.
All members of the PowerStick family maintain
the complete feature set of Vicor 2nd Generation
converters. And, because PowerSticks are
environmentally sealed and encased in aluminum,
they offer superior ruggedness, reliability,
electrical shielding and noise performance.
Low voltage models incorporate Vicor’s
innovative Smart RectificationTM for high
efficiency.
