Notes
|
1. All parameters NOT specially mentioned are measured at 110V/277VAC input , rated load and
25℃of ambient temperature.
2. Ripple& noise are measured at 20MHz of bandwidth by using a 12”twisted
pair-wire terminated with a 0.1uf &47uf parallel capacitor.
3. Tolerance:includes set us tolerance,line regulation and load regulation .

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.
