LED driver is a self contained ac dc power supply which regulates the power required for leds.

Current LED solutions offer excellent dimming mode options using DALI, Push-Dim or 0/1-10V, Phase Cut, while several LED drivers need to be controlled in parallel, providing an additional power supply for external sensors. From safe power supply units to creative light control via wireless interfaces. Modular LED power supply systems allow components to be combined in a solution that precisely meets of the various application needs, such as indoor and outdoor lighting, LED signage designs, LED string, also residential and commercial lighting etc..

LED power supply units and LED drivers are required to offer a maximum working efficiency, power factor (we call it as“PFC”), total harmonic distortion (THD) are subject to particular requirements with the safety standard (EN 61347-1/-2-13), EMC (EN 55015), harmonic current emissions and further specific requirements of standards like UL and CE (IEC+ LVD).
