Scope and starting point
Particular safety requirements for electronic controlgear for LED light sources. Use it with the referenced general requirements.
Selection notes
Match the complete model suffix, rated current and constant-current voltage window. Allow for cold and hot LED-string voltage, temperature derating, dimming compatibility and enclosure conditions. This preliminary comparison is not an isolation, wiring or electrical-safety approval.
Keep a reproducible record
Save the complete part number, source revision, operating point and the reason for each decision. Keep calculated examples separate from observed results. A measurement report needs its sample identifier, instrument and calibration details, stabilization, ambient conditions, raw record and uncertainty statement. Do not replace a missing value with zero or a typical value with a guaranteed limit.
