Conrm the forward current and voltage required by the luminaires
Conrm the LED lumen required and the suitable LED (chip) brand. Then, choose the tting LED drivers based on the forward
current and forward Voltage ( Vf ) of the specication.
Conrm the application and function of the luminaires (driver)
After acquiring the forward current and forward voltage of the LED specications, choosing the driver models according to the
application and design of the luminaire, such as indoor/ outdoor application/ PFC / waterproof protection /dimming function/
input voltage range /safety regulations… etc.
Choose the suitable LED drivers from MEAN WELL website
Conrm all the required functions. Through “Quick Search” of MEAN WELL website, choose the appropriate LED drivers via the
options provided.
Conrm the specications of the LED drivers
When nding the suitable products through “ Quick search”, please refer to the product specication to conrm the voltage
range and current of the driver and the related electrical features: dimming functions / waterproof function / operating
temperature/warranty and other requirements. Furthermore, it is recommended that the lowest usage range of the chosen LED
driver voltage is at least 2V higher than the actual application Vf voltage to avoid the LED light ashing due to the situation that
Vf decreases when operating. In addition, when selecting the driver, add 20% wattage of the actual lamp to reduce the quality
problems caused by the long-term operation and the high ambient temperature.
Contact MEAN WELL sales or distributors
After conrming the specications of the product; however, unable to choose suitable products, please feel free to contact
MEAN WELL sales or distributors through website Sales Inquiry to make an inquiry, including if the selection is appropriate/
samples can be purchased…etc. Moreover, if you have purchased a sample, please test the electrical features and temperature
of the drivers with the luminaire to ensure that luminaires have the best heat dissipation convection / optical design and correct
electrical features.
