  FAQ  

1.  Is there a Tc point on the driver? And do you have a lifetime derating curve for case temperature? At 60 Watt load we are seeing a case temperature of 60°C.


Answer:  The TC point is right above on the led transformer when you test it. So far, we didn't show it on the lables. If it is necessary for you, we will show TC point on the next orders, ok?Enclosed please find the picture of  derating curve for your reference.
 
 
2. What is the wire gauge that fits into the ETL Triac Dimmable LED Driver? 
Answer: 14-26 AWG
 
3. What is the difference between the 20w/45w UL and 24w/48w ETL model?
Answer:
-- when you install a 20w/45w UL led driver in your led light you should consider abbot min. 55% load limtation. If it less than 55%, the led light will have flick problem.  But the 20w/45w ETL model is no load limitation. You can load it in the led light 1-48w.
-- the height of 24w(20mm)/48w(24mm) is lower than 20w(28mm)/45w(34mm).
