Servers and high-performance workstations represent the most technically demanding IS/IEC 62368-1:2023 certification challenge due to their classification as PS3 power sources.
Under IS/IEC 62368-1:2023, power sources above 240VA are classified as PS3. Servers commonly have PSUs of 500W to 2000W — firmly in PS3 territory. PS3 power sources require the highest level of safeguards:
Rack servers are typically accessed by trained IT professionals in data centres — they have different user interaction scenarios than consumer products. IS/IEC 62368-1:2023 provides some provisions for products intended for use only by trained individuals in restricted access locations.
Server hot-swap PSUs can be removed and inserted while the server is running. The safety evaluation must address the exposed contacts during PSU hot-swap operations.
Blade server chassis use high-voltage DC bus (typically 380V DC or 48V DC). This internal high-voltage bus requires careful safety evaluation under IS/IEC 62368-1:2023 for the PS3 class energy.
Server manufacturers should engage a BIS-recognized lab with specific IS/IEC 62368-1:2023 PS3 experience before formal testing. The documentation requirements for PS3 products are more extensive than for lower power products. Budget 4-6 weeks additional preparation time compared to consumer products. Migration deadline: November 2028. Start now.
