12 volt 24 volt 300w phase cut dimming led drivers
Smarts phase dimming constant voltage led driver are compatible are compatible with both forward phase (leading edge, triac, incandescent) and reverse phase (electronic lowvoltage, ELV, and trailing edge) dimmers. And all of they had the protection like overload, over temprature and over current protection, that would be safety when anything happened. Higher security level than meanwell's ordinary LED power supply 300W
