IMPORTANT MESSAGE:  Acuity Brands announced that the OPTOTRONIC® LED driver product families were becoming part of the eldoLED™ brand. To align with the transition, OPTOTRONIC product labels, specification sheets, and datasheets incorporated the eldoLED logo as of November 16, 2021. 

OPTOTRONIC Programmable Compact

Dimmable LED Drivers

eldoLED *2743W1 OPTOTRONIC 40W Constant Current LED Driver, 0-10V Dimmable OTi40W/120-277/1A4 DIM-1 (Osram 57351) 

The OPTOTRONIC Compact Drivers have several architectural-grade features that offer functionality that supports architectural lighting design. OPTOTRONIC LED drivers support true 1% dimming across the entire driver programmable output current range. This key specification gives lighting designers the flexibility and precise light output they require. The synchronized ON/OFF timing and dimming control meet efficacy requirements and ensure consistent dimming levels across multiple luminaires. The DIM-to-OFF feature enables luminaires to smoothly transition from dim to off. And, offers an AUX power output option to power and extend DIM-to-OFF capability to fixture-integrated sensors and controls.

OEMs can fully customize programmable features into a driver which helps optimize production line efficiency by utilizing the one-click programming feature of the OPTOTRONIC Programmer. The OPTOTRONIC Programmer does not require the power supply to be powered up or connected to AC line voltage while programming.
