MEAN WELL LED Driver Dimming Wire Colour Change

MEAN WELL LED Driver Dimming Wire Colour Change

In 2022 the colours of the dimming wires on all MEAN WELL LED drivers changed from Blue & White to Pink & Purple.

The change was made so that MEAN WELL LED drivers comply with the revised NFPA 70 (National Fire Protection Association) and NEC 2020 (National Electrical Code) regulations that have come into effect in North America.  

The change to production took place during Q1 2022.

We would lik to take this opportunity to advise customers to be sure that the polarity is correct when wiring up their dimmers, as there is the potential for dimmers to fail if the polarity is incorrect.
