IEC TR 63282:2024, which is a technical report, collects information and report experience for the standardization of voltage levels and related aspects (power quality, EMC, measurement, etc.) for LVDC systems (systems with nominal voltage up to and including 1 500 V DC). Rationale for the proposed voltage values is given. Variation of parameters for the voltage (power quality) for their…

This document specifies principles for the design of agricultural machinery and tractors utilizing systems (perception, supervisory or other) to prevent unintended excursions beyond the boundary of the autonomous operating zone which are used in agricultural applications and that have partially automated, semi-autonomous and autonomous functions. Additionally, it provides guidance on the type of…
