What is a Constant Current Power Supply?

HLG-120H/185H-C series (120V/350mA/500mA/700mA/1050mA/1400mA) single output constant current LED power supply possess up to 94% of high efficiency,so they can be cooled by free air convection from -25oC to +70oC ambient temperature.These two series have three options (A/B/D type) in different mechanisms and functions for your selection.For A type model, users can adjust the current range from 50% to 100% by internal potentiometer; B type equips with three-in-one dimming function (1~10VDC, PWM, resistance), while D type (optional model) equips with “multiple stage timer dimming” function that can be customized by request. Besides standard functions of protections for short circuit, over voltage, and over temperature, these power units comply with global certificates per UL/ CUL/ ENEC/ CB/ CE, including UL8750, ENEC EN61347-2-13, EN62384 of lighting regulations. Suitable applications include LED street lighting designed with single series connected LED strips and high driving voltage, LED tunnel lighting, LED spot lighting, LED high bay lighting.
