Technical Specification
Kilo, Mega, Giga, Tera
Half-brick
w/ Baseplate
High Efficiency, Isolated DC/DC Converter, with Baseplate
This technical addendum contains additional specifica-
tions for the baseplated version of the PowerQor Kilo,
Mega, Giga, Tera half-brick series of converters. This
unit is manufactured by adding an industry standard size
baseplate to the non-baseplated half-brick converter
using standard mounting techniques. The baseplated
version allows for optional heatsinking in severe thermal
environments or for mounting to a cold plate. Please
refer to the HxAxx specification sheets for all specifica-
tions that are not included in this addendum.
