OTi25W/120-277/1A2/DIM-1 AUX Optotronic
Description
Description
The eldoLED OPTOTRONIC OTi 25W Compact is a high-performance, programmable constant current LED driver designed for architectural and commercial lighting projects. Delivering up to 25W of output power with a programmable current range of 150–1250mA, it provides precise, flicker-free illumination for small and medium-sized LED fixtures. With isolated 0–10V dimming down to 1% and dim-to-off capability, this driver allows smooth and energy-efficient light control. Optional AUX output models provide 12V/20V/24V power for auxiliary circuits, offering added flexibility for complex lighting installations.
Ideal for indoor dry and damp locations, the OTi 25W Compact supports universal input voltage from 120–277V AC, ensuring broad compatibility. Its compact F-style or J-style housing simplifies installation in tight spaces, while Class P UL listing, thermal protection, and comprehensive overload, over-voltage, short-circuit, and over-temperature protections guarantee safe and reliable operation. Soft start, dimming synchronization, and constant lumen output features make this driver a dependable choice for commercial and architectural designers seeking compact, efficient, and long-lasting LED control solutions.
