※Input power cord: AC (L), (N), and earth wire (G)
※Output Red is（DIM+）,Black is（DIM-）
Dimming Operation
1) 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.
2) Usually matching with Forward phase , leading edge , Magnetic low voltage, triac dimmers, or Reverse phase,
trailing edge ,Electric low voltage Dimmers.
3) lease try to use dimmers with power at least 1.5 times as the output power of the driver
