Mechanical Specification for led strip power supply
※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.
Dimming Operation for 24v power supply
※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.
Derating Curve for 277VAC LED DRIVER
※To extend their life, please refer to the Derating Curve and derate according to the temperature.
