 Mechanical Specification

UL 277 volt dimmable led power supply 24v 

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

Output: Red isDIM+,Black isDIM-

※Note: Any other requests we can customized.

 

■Dimming Operation

※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.
