Aircraft electronics and other electrically powered equipment aboard an aircraft are subject to some of most extreme power conditions. To ensure that avionics will operate reliably once in the air, they are subjected to a wide variety of tests that prove their ability to withstand over-and under-voltage conditions, power dropouts, and voltage transients. MIL-STD-704 ‘Aircraft Electric Power Characteristics’ establishes the requirements and characteristics of aircraft electric power, while MIL-HDBK-704-7 and MIL-HDBK-704-8 describe the test methods and procedures for equipment designed to operate from 270 VDC and 28 VDC power, respectively.

Elektro-Automatik’s line of DC power supplies, electronic loads and bidirectional power supplies have features that will put today’s avionics to the test and still meet future needs. EA’s PSI, EL, ELR and PSB product series can provide up to 2000V, have auto-ranging and on-board arbitrary waveform and function generation. This flexibility allows EA to produce or sink power needed to simulate real world conditions and ensure that avionics and airborne equipment will continue operate even in the most adverse conditions.
