Full title and description
ISO 2277:1973 — Static invertors for aircraft. Specifies general design and test requirements for 400 Hz static invertors used in aircraft electrical power systems, including preferred ratings, supply characteristics, output voltage and frequency, efficiency, regulation, waveform and modulation, protection, environmental and electromagnetic considerations, tests, marking and declarations.
Abstract
Sets out the general design and test requirements for 400 Hz inverters intended for aircraft service. The standard gives preferred ratings, supply and output characteristics, requirements for efficiency, regulation response and stability, voltage balance and waveform quality, controls and adjustments, phase sequence, protection, environmental and EMC considerations, component and terminal identification, starting and cooling arrangements, test methods, and required declarations and marking.

Scope
This standard applies to static (solid-state) invertors designed to supply 400 Hz alternating current for aircraft electrical systems. It covers design and performance parameters, control and protection requirements, environmental and electromagnetic compatibility considerations, required tests, and marking/declaration obligations for manufacturers and test laboratories. The scope is focused on inverters intended for installation and operation on aircraft rather than ground-based power equipment.
Key topics and requirements
- General design requirements for static invertors used in aircraft.
- Preferred electrical ratings and supply characteristics (input and output specifications).
- Output voltage, frequency (400 Hz), waveform quality and modulation requirements.
- Efficiency, regulation response, stability and voltage balance criteria.
- Control of voltage and frequency, adjustment provisions and phase sequence.
- Protection features (overload, short-circuit, thermal protection) and cooling/starting arrangements.
- Environmental requirements and tests (temperature, vibration, humidity, etc.).
- Radio interference and magnetic influence considerations (EMC-related performance).
- Terminal and component identification, declarations by manufacturer, and marking requirements.
- Specified tests and test documentation to demonstrate conformity with the standard.
Typical use and users
Used by aircraft electrical and avionics design engineers, OEMs of aircraft power systems, test laboratories, certification bodies, maintenance organisations and suppliers of static invertors intended for aviation applications. It supports design verification, type approval testing and procurement specifications for aircraft electrical equipment.
Related standards
Complementary standards include other ISO and IEC documents addressing aircraft electrical power systems, electromagnetic compatibility (EMC) and electrical safety, as well as civil aviation authority technical specifications and equipment airworthiness requirements. Users commonly consult applicable national aviation regulations and related IEC standards when applying ISO 2277 in design or certification contexts.

FAQ
Q: What is this standard?
A: ISO 2277:1973 is an International Standard that specifies design and test requirements for static (solid-state) invertors intended for use on aircraft, focused on 400 Hz output equipment.
Q: What does it cover?
A: It covers preferred ratings, supply and output characteristics, voltage and frequency control, efficiency and regulation, waveform and modulation, protection and cooling, environmental and EMC considerations, tests, declarations and marking for aircraft static invertors.
Q: Who typically uses it?
A: Aircraft OEMs, avionics and power-system engineers, component manufacturers, test laboratories, maintenance organisations and certification authorities use the standard for design guidance, testing and procurement.
Q: Is it current or superseded?
A: The published 1973 edition remains an ISO International Standard and has been subject to periodic review/confirmation under ISO procedures; it is recorded as a confirmed international standard rather than having been withdrawn or replaced (confirmation recorded in ISO lifecycle information).
Q: Is it part of a series?
A: It is a standalone ISO technical standard addressing static invertors for aircraft; it is related in subject matter to other ISO/IEC standards covering aircraft electrical systems and EMC but is not presented as part of a numbered series of ISO 2277 documents.
