Description
Description
The eldoLED OPTOTRONIC OTi 25W 347V Compact is a versatile, programmable LED driver designed for 347V systems in commercial and architectural lighting. Delivering up to 25W of constant current output, it offers a wide programmable range of 150–1250mA (1mA increments, factory default 500mA) for precise LED control. Its compact form factor and advanced protection features make it ideal for installations with limited space while maintaining high performance and reliability.
This driver supports isolated 0–10V dimming down to 1% with dim-to-off functionality, and optional auxiliary (AUX) output for powering sensors, wireless controllers, or other controls directly from the driver. With NTC thermal foldback, overload protection, IP20 indoor rating, and compliance with UL, FCC, and RoHS standards, it provides safe, energy-efficient operation for indoor commercial, retail, and architectural lighting applications.
