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.
Derating Curve
- Load carried in accordance with the load derating curve, according to the ambient temperature derating, in order to extend the service life.
What do you mean by constant voltage source?
A constant voltage source is a power source which provides a constant voltage to a load, even despite changes and variance in load resistance. In other words, the voltage which a constant voltage source provides is steady, even if the resistance of the load varies. Hence how to connect the triac dimmable constant voltage with led driver? Please see as below:
