Choosing the correct power supply
Check the LED module’s required DC voltage, total load, mounting space and terminal layout against this model. The specified output range is 4.5–4.7Vdc. Above +50°C, apply the manufacturer’s linear derating curve instead of assuming full output up to +70°C. Allow ventilation around the supply.
