※Input:18AWG Black and White to be connected to AC L and N ,Green wire go ground,

※Output wire: 16AWG ,  Red is(DIM+),Black is(DIM-)

※Class 2 standard output terminal. Three groups of cables for SMT-012-180VTHJ / SMT-012-180VTHJV2 / SMT-012-180VTHJWV2 ; two groups for SMT-024-192VTHJ / SMT-024-288VTHJV2 / SMT-024-288VTHJWV2


  ■Dimming Operation  

※The Pulse-Width Modulation (PWM) of output voltage can be adjusted through input terminal of the AC phase line(L) by connection a phase/triac dimmer.

※Usually matching with Forward phase , leading edge , Magnetic low voltage, triac dimmers, or Reverse phase, trailing edge ,Electric low voltage Dimmers.  

※Please try to use dimmers with power at least 1.5 times as the output power of the driver.

  ■Derating Curve
