Engineering Review Focus
Use the installation-site environmental specification instead of regional climate assumptions.
Derive current derating from measured loss and thermal resistance; do not apply a fixed percentage.
Select insulation materials and protection methods from the applicable system standard and enclosure design.
Define damp heat, salt mist, temperature cycling and post-test electrical checks in the project DVP.
Project Inputs Required
Topology and operating mode
Input and output voltage range
RMS, peak and ripple current
Switching frequency and waveform
Cooling, ambient and mounting method
Insulation, mechanical envelope and validation plan
Evidence Boundary
This guide does not prescribe a regional ambient temperature, IP rating, insulation class, derating percentage or test duration. Those values must come from the installation and qualification specification.
