Mechanical Specification for 300 watt led driver
※Input: 3 * 18AWG Black and White to be connected to AC L and N ,Green wire go ground,
※Output: Red is（DIM+）,Black is（DIM-）/ 2 * UL 14AWG power cord
Dimming Operation for led driver 12v
※Output PWM of output voltage can be adjusted through input terminal of the AC phase line(L) by connection a
triac dimmer.
※Compatible with Leading edge or Reverse phase, trailing edge triac dimmers, Magnetic low voltage dimmers,
Electric low voltage Dimmers..
※Please try to use dimmers with power at least 1.5 times as the output power of the driver.
