What is the factors that will affect inrush current in a led driver ?
instantaneous inrush current is related to input voltage, load capacity and current surge time to a led driver. we have show this rate to the datasheet of each our dimmable led driver 12v 30w to 300w, constant current and constant voltage led drivers, kindly refer to our online datasheet or contact us to get more details.

dimming operation


1. output constant current level can be adjusted through input terminal of the ac phase line(L) by connection a triac dimmer.

2. compatible with leading edge or tailing edge triac dimmers.

3. please try to use the small power dimmer, have access to a wider dimming range, high-power dimmer is difficult to achieve the output current to zero.
