 pair-wire terminated with a 0.1uf &47uf parallel capacitor.

3.Tolerance:includes set us tolerance,line regulation and load regulation .

45W triac dimmable constant voltage LED driver Mechanical Specification  

  • Input Brown with AC (L),Blue with AC(N)
  • Output Red is(DIM+),Black is(DIM-)
  • Note: Any other requests we can customized.

Dimming Operation

  • Output constant current level can be adjusted through input terminal of the AC phase line(L) by connection a triac dimmer.
  • Compatible with Leading edge or tailing edge triac dimmers.
  • please try to use the small power dimmer, have access to a wider dimming range, high-power dimmer is difficult to achieve the output current to zero

 We can supply you ETL approved Junction boxes for all kinds of the LED drivers.
