MAH-SERIES

(Nominal Voltage Input, Quad Output)

Design Methodology

Declared Parts Lists defining the EEE parts technical standard and Declared Materials Lists with material

data including outgassing and surface treatment is part of the design standard.

The MAH-Series is developed using a proven conservative design methodology, which includes selecting

radiation tolerant, and established reliability components and fully derating to the requirements of EEE-INST-

002 and ECSS-Q-ST-11. In addition to verification and qualification testing and full acceptance testing for

deliverable units, the performance characteristics are verified by theoretical analysis including worst case

analysis including radiation degradation, parts stress analysis, mechanical analysis and thermal analysis.

Reliability Assessment per MIL-HDBK-217F has also been carried out.

Generic Envelope Data Sheet & Existing Models Listings

The MAH-Series is made as a generic design allowing for adaptations to different satellite power buses and

TM/TC systems, different output voltages and currents within the overall envelope specification defined for

the ML-Series.

For each released variant of the MAH-Series detailed data sheet exists with exact data for all parameters.

Existing variants are listed in Table below.

A generic envelope data sheet is presented to indicate the envelope specification within which the MAH-

Series can be adapted to specific customer requirements that cannot be met with one of the existing model

variants listed in Table below.

Where the generic data sheet lists Min rated or Max rated value, it is necessary to look up the actual

parameter in the data sheet for the specific variant in question – for new variants please contact IR HiRel

Sales department.
