Problem analysis
1.Question: In the diagram spec sheet it show the dimmer on the N (neutral)? Normally Triac the dimmer is on the L Line?
Answer: Dimmer can be connected on the N (neutral) or on the L (Line). Depending on you.
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.
