BTL is following IEEE 3458-2026 for domain-specific LLM management platforms. It recommends reproducible, use-specific evaluation of task quality, data permissions, security, service performance and version changes to support traceable enterprise AI adoption decisions....[+more]
Facing high-density racks of 100–130kW or more (such as NVL72), the chiller serves as the “heat exchange heart” on the facility side. Through dual-loop isolation design, 15–25°C high-temperature supply water to prevent condensation, free cooling, and second-level variable-frequency regulation, it ensures GPUs with 700–1200W TDP can sustain full load operation without throttling, achieving an annua...[+more]
Focusing on the IEC 62040-2 standard, this analysis comprehensively breaks down the core EMC testing requirements for uninterruptible power supplies (UPS), providing professional compliance guidance for the industry....[+more]
BTL highlights grid-edge integration and distributed energy resources, focusing on safety and coordination across storage, V2G, microgrids and virtual power plants. BTL recommends assessing electrical safety, grid protection, interoperability, cybersecurity and fault recovery against product functions, site conditions and local requirements to establish traceable validation, while continuing to fo...[+more]
On September 7, 2026, the EU added the updated EN 50566 to RED harmonized standards. Body SAR testing is changed to 0 mm contact with unchanged limits for 30MHz-6GHz close-range wireless devices. There is an 18-month transition period; new certifications must follow the new standard afterwards, and old models on sale need recertification....[+more]
IEC and IEEE published IEC/IEEE 62209-1528:2020/AMD1:2026 on 2 September 2026, updating SAR measurement requirements for hand-held and body-mounted wireless devices. The amendment addresses hand SAR, sensor validation, time-averaged SAR, separation distance and test reduction, requiring manufacturers and laboratories to review the impact on existing test procedures....[+more]
The main changes are as follows: the application standards have been changed to CNS 15598-1, CNS 15936, and CNS 62133-2; a new standard CNS 15663 (products listed in Tables 01-03) has been added; new product names to be inspected include: secondary lithium battery charging boxes and secondary lithium mobile vehicle starter power supplies; and secondary lithium mobile power supplies listed in Table...[+more]
When applying for CE certification for Wi-Fi 5GHz Band4, manufacturers often face challenges in selecting among EN 300 440, EN 301 893 and EN 302 502. This article compares key indicators of the three standards, including frequency range, operating bandwidth, EIRP output, DFS and country detection capability. It interprets regional power limits, software based country switching and mandatory DFS r...[+more]
