Introduction
KFLY’s 15W×2 and 30W×2 series of fixed-output-current LED drivers are suitable for both explosion-proof and general lighting applications. These drivers meet global certification standards and feature comprehensive built-in protection against abnormal operating conditions, ensuring safety even in the event of wiring faults or LED board damage. Designed to Class I luminaire standards for easy installation, the units utilize internal circuitry and components engineered to meet standards for sand-filled (Ex q) explosion-proof equipment, with internal cavities fully encapsulated in silicone. Additionally, their high efficiency meets energy-saving requirements, and optimal EMC performance was a key priority during development. Meticulously designed and rigorously tested, these drivers perform reliably across diverse lighting conditions; their exceptional durability offers customers peace of mind and reduces maintenance costs.
