  Problem analysis  


1.Question: What is the wire gauge that fits into the UL Triac Dimmable LED Driver? 

 Answer: 14-26 AWG

2. Question:Just to confirm the drivers are Three In One Dimming Function Compatible With Leading-edge/Trailing-edge Dimmer, No Flicker? No Min load?

Answer: Our Triac dimmable led drivers are compatible with Leading-edge/Trailing-edge Dimmer,no flicker,no min load.


3.Question:  If all dimmable LED drivers we ordered will provide more than 12 or 24 volts? As our some of LED lighting 's voltage is more than 24VDC a bit .

Answer:  ±0.5% is the acceptable margin of error for both 12v dc and 24vdc led drivers.
