Connecting Diagram
Simple Connection Diagram
What is the dimming Operation for SMT-024-100VTSW?
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.
