Approved American National Standard
ANSI/VITA 62.0
Modular Power Supply Standard
Abstract
This standard provides requirements building a power supply module that can be used to
power a VPX chassis. The module will fit within the standard envelope defined for VPX
modules in the VITA 48.0 specifications.
Approved June 2012
American National Standards Institute, Inc.
American
National
Standard
Approval of an American National Standard requires verification by
ANSI that the requirements for due process, consensus, and other criteria
for approval have been met by the standards developer.
Consensus is established when, in the judgment of the ANSI Board of
Standards Review, substantial agreement has been reached by directly
and materially affected interests. Substantial agreement means much
more than a simple majority, but not necessarily unanimity. Consensus
requires that all views and objections be considered, and that a concerted
effort be made toward their resolution.
The use of American National Standards is completely voluntary; their
existence does not in any respect preclude anyone, whether he has
approved the standards or not, from manufacturing, marketing,
purchasing, or using products, processes, or procedures not conforming
to the standards.
The American National Standards Institute does not develop standards
and will in no circumstances give an interpretation of any American
National Standard. Moreover, no person shall have the right or authority
to issue an interpretation of an American National Standard in the name
of the American National Standard Institute. Requests for interpretations
should be addressed to the secretariat or sponsor whose name appears on
the title page of this standard.
CAUTION NOTICE: This American National Standard may be revised
or withdrawn at any time. The procedures of the American National
Standards Institute require that action be taken periodically to reaffirm,
revise, or withdraw this standard. Purchases of American National
Standards may receive current information on all standard by calling or
writing the American National Standards Institute.
NOTE – The user’s attention is called to the possibility that compliance with this standard may require use
of an invention covered by patent rights.
By publication of this standard, no position is taken with respect to the validity of this claim or of any patent
rights in connection therewith. The patent holder has, however, filed a statement of willingness to grant a
license under these rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to
obtain such a license. Details may be obtained from the standards developer.
