High Reliability, Dual Output Avionics Power Supply

Design Note #56

High Reliability, Dual Output Avionics Power Supply

OTEC was selected to develop a High Reliability, Ruggedized Dual Output Power Supply for use in demanding avionics applications. Optimization of Power Supply size and weight were critical to the design’s success. Working closely with our component vendors, OTEC crafted a proven 150,000 Hour MTBF solution.

Hot Swappable, Low MTTR, Light Weight

Maintainability, rapid field replacement, and light weight requirements added to the design challenge. A unique power-edge finger mating approach made hot swap and MTTR easy. Component weight is rarely a consideration in electronics design, however in this design each part had its own weight budget–including the circuit board.

Microprocessor Supervision

High output voltage stability with low current noise is essential over the entire extended operating range. Brown-out detection, over and under voltage protection, and thermal protection are performed with an on-board power supply microcontroller. Advanced error detection and power supply status monitoring achieve extraordinary output performance.
