Dimming Operation
TRIAC/Phase cut dimming
1.The Pulse-Width Modulation (PWM) of output voltage can be adjusted through input terminal of the AC phase line(L) by connection
2.phase /Triac dimmer or lighting system.
3.Working with forward phase, MLV and Reverse phase , ELV, TRIAC dimmers.
4.Min. loading is about 10%.
5.Please try to use dimmers with power at least 1.5 times as the output power of the driver.
Derating Curve
1.To extend their life, please refer to the Derating Curve and derate according to the temperature.
2.Please note that the rise in temperature of LED fixtures over a long period of time will cause their power to rise. Therefore, we recommend the power supply to reserve a certain amount of load to avoid overloading.
