Astrodyne Acquires RO
RO Logo
Welcome to April's newsletter where this month we are focusing on high reliability power supplies. With the recent acquisition of RO Associates, Astrodyne has added a new family to its product line offerings to include High Reliability/COTS DC/DC converters.  We are very excited about expanding our offerings and look forward to introducing new products to meet the diverse power supply industry needs.

Q:  What does High Reliability Mean?
 
 A:  High Reliability products routinely exceed the lifetime of similar products of comparable mechanical and electrical design.  High Reliability in power supplies can be achieved through the use of higher-rated components.  These parts' parameters will drift less over time and extend the useful life of the product.  Regardless of the component ratings, safe design margins are an integral part of high reliability design. Considerations must be included for environmental, electrical and mechanical stress.
Thermal Considerations for High Density DC Modules
Thermal ConsiderationsThermal considerations are key factors in the life and reliability of any electrical system.  Harsh environments including temperature extremes and rapid changes require careful selection and integration of DC modules.  Thermal transfer to reduce thermal stress on any device is critical to the units operating properly over time.  Poor thermal management can have a cascading effect which can result in poor performance or premature failure.  Read More...
Current Sharing for High Density DC Modules
Current ConsiderationsCurrent sharing techniques are an effective method to increase system reliability.  When High Density Modules are paralleled, the system load is shared equally among the modules preventing any single module from being overstressed.  In addition, applications can protect against a single module failure with paralleling techniques.  Read More...
