Material features in the Aircraft industry

Aircraft electrical system sees in itself a fundamental contradiction between power generation and power utilization where the onboard equipment requires perfectly regulated and transient-free power supply while the generation side and power source expects the load to remain constant and non-distorting. The essentialness of safety and performance of on-board system is thus critical for civil and commercial aircraft, where all airborne equipment depends on reliable electrical power.

As aircraft systems have been constantly evolving from the traditional parameters of 115/200V AC three-phase at a fixed frequency of 400Hz to the currently industrially acknowledged variable-frequency system with "wild frequency" between 360Hz and 800Hz, so do testing solutions and equipment advance ahead with the development.

To ensure compliance and airworthiness, avionics and electrical equipment are tested according to rigorous civil aviation power standards, including:

• RTCA/DO-160 and EUROCAE ED-14 for environmental and power immunity testing;
• Manufacturer-specific derivatives such as Airbus ABD0100.1.8 (A380), ABD0100.1.8.1 (A350), AMD24C (A400M), and Boeing B787 (Dreamliner) power quality standards;
• As well as equivalent regional standards that align with these core guidelines.

To meet these requirements, laboratory power sources must simulate both steady-state and transient behaviours with high fidelity—delivering fast response, wide frequency range, precise control, and strong overload capacity.

In essence, aircraft power testing is about reproducing the non-ideal realities of flight with precision and consistency. ActionPower’s programmable AC and DC power sources and test systems empower engineers to achieve this with confidence.
