MIL-HDBK-845

Abstract

This handbook is written to be an informational aid for electronic system designers who use or plan to use Standard Power Supplies (SPS). Included are performance characteristics of SPS, electrical and mechanical interface requirements, and general applications guidance and instructions. <br>The term Standard Power Supply (SPS) refers to any one of a group of low voltage power supplies which are designed and manufactured to meet requirements established under the Navy's Standard Hardware Acquisition and Reliability Program (SHARP). The purpose of this effort is to provide system designers with a group of power supplies with varied standard input/output capabilities which meet established performance, reliability, and maintainability criteria. SPS represents one step toward realizing system acquisition through the use of standardized hardware usage. By selecting from this group, system designers can reduce many of the initial acquisition costs associated with power supply design, test, and implementation. SPS designs are often born out of the need for certain power supply capabilities in new electronic systems. As a result, the first user often influences which capabilities are built into each supply. The standardization philosophy builds on the needs of individual system requirements and outlines a power supply which can be used in multiple applications. <br>Standard Power Supplies are categorized into two groups: Shipboard Power Supply Products (SPSP) and Airborne Power Supply Products (APSP). SPSP are intended for use specifically in shipboard applications and are designed in accordance with MIL-P-24764. APSP are designed for airborne applications to the requirements of MIL-P-29590. <br>This document addresses several significant applications criteria for SPS. The information is separated between SPSP and APSP for each criteria. In those cases where the information is appropriate to both airborne and shipboard applications, it is not repeated.
