※Input:18AWG Black and White to be connected to AC L and N ,Green wire go ground,
※Output: Red is（DIM+）,Black is（DIM-）
※Note: Any other requests we can customized.
※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 trailing edge triac dimmers, but trailing edge dimmers work better..
※Please try to use dimmers with power at least 1.5 times as the output power of the driver.
- Load carried in accordance with the load derating curve, according to the ambient temperature derating, in order to extend the service life
