Pre-sales consultation process

Demand analysis and solution matching

Technical parameter confirmation

Collect core parameters such as voltage level (single phase/three phase), current specification (16A-125A), interface type (IEC/C19/C13), protection level (IP20-IP67) through the “Customer Demand Survey Form”.

Scenario adaptation suggestions

recommend additional functions such as lightning protection, temperature control, and metering monitoring based on customer application scenarios (data center/industrial computer room/medical equipment/5G base station).

Solution 3D modeling

Provide SolidWorks/CAD dynamic drawings and BOM lists, marking key indicators like dimensional tolerance (±0.5mm) and material flame retardant level (UL94 V0) for precise manufacturing.

Technical Laboratory Simulation Test

All YOSUN custom PDUs are issued with CNAS certification test reports and CE/UL/TUV compliance documents.

Including overload test (1.25 times rated current for 2 hours)

Plug life test (≥5000 times)

Salt spray test (72 hours)

Confirmation of PDUs business terms
