S.I. Series Programmable LED Drivers

LTF SI Series Smart Interface Programmable LED drivers are high-performance power supplies, providing ultra-smooth, continuous <1% dimming for virtually any LED application.

Providing both constant current or constant voltage, it is the most versatile LED driver in the lighting industry due to its compatibility with a wide variety of LED arrays, multiple form factors, and numerous control options.

Over Temperature Protection (OTP) supports thermal feedback, providing extra protection for LED loads; controlled and adjusted by SI setting software to decrease output current.

SI Programmable Series drivers are an ideal solution for both enhanced flexibility and control of architectural lighting, as well as SKU reduction on the manufacturing side of OEM lighting.
