Full title and description

ISO 27027:2014 — Aerospace — Solid-state remote power controllers — General performance requirements. This international standard specifies definitions, general performance requirements and test methods for solid-state (remote) power controllers (SSPC) intended for use in aerospace electrical power systems, covering the electrical, thermal and functional behaviour of the SSPC and associated control/status functions.

Abstract

ISO 27027:2014 defines the scope, terminology and the general performance and test requirements used to determine the suitability of solid-state remote power controllers (SSPC) for aerospace applications. It addresses the SSPC as a combination of solid-state switching devices and the associated circuitry that provides protection, control-signal handling and status information.

Scope

This standard specifies the definitions, titles of general performance requirements and the associated test methods to determine the performance of solid-state remote power controllers (SSPC) for use in aerospace electrical power systems. It applies to SSPC assemblies consisting of solid-state switching devices together with the solid-state circuitry required for protection, control-signal response and status reporting under the environmental and electrical conditions typical of aerospace platforms.

Key topics and requirements

• Definitions and terminology for SSPC components and functions.
• General performance requirement categories (electrical, thermal, functional and reliability aspects).
• Test methods to verify switching performance, overload/short‑circuit protection and thermal behaviour.
• Requirements for control-signal acting, status output and diagnostic information.
• Environmental and operational conditions typical to aerospace applications to be considered during testing.
• Reference to prior edition and normative references for related test procedures and definitions.

Typical use and users

Used by aerospace equipment designers and manufacturers, suppliers of solid-state remote power controllers, test laboratories, certification bodies and technical procurement teams. Typical applications include aircraft and spacecraft electrical power distribution systems where SSPCs replace or complement conventional electromechanical circuit breakers.
