LED power supply is a kind of light source that utilizes PWM control mode. It is protected by short circuit, overload and over voltage. In order to ensure high reliability and high efficiency, it provides constant voltage. This supply meets to standard LVD and EMC. And it is built in emi filter, low ripple noise. The other advantages of the power supply are compact size, light weight, low working temperature, soft-start circuit, limiting AC surge current, save energy, entironment-friendly. LED power supply from the HLG, CLG, PLC, CEN, ELN, LP, ULP & PLP Series forms a complete range of LED power solutions for both indoor and outdoor LED lighting applications. It is are widely applied in moving signs, back lighting, led-based decorative/architectural lighting, LED stage and theatre lighting, electronic LED displays. In addition, IP rating can make this supply used in other applications where ingress of dust or moisture is a concern with protection levels making them splashproof&waterproof.
