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or withdrawn at any time.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.
