OPTOTRONIC OTi 85W Programmable Linear LED Drive, *2743W5 57420-Oti85/120-277/2A3/DIM-1 LSynchronize ON/OFF Timing and Dimming Controls: This feature meets efficacy requirements and ensures consistent dimming levels across multiple luminaires and individual luminaires that require multiple drivers.True 1% Dimming: Architectural LED drivers support 1% dimming across the entire driver programmable output current range for True 1% dimming. For example, if a driver is programmed to 300mA, then at 1% dimming, output current would be 3mA.DIM-to-OFF: DIM-to-OFF enables luminaires to smoothly transition from DIM-to-OFF and save energy without needing additional control equipment to turn off the fixture. Select architectural-grade LED drivers offer DIM-to-OFF and have a programmable AUX power output option to power and extend DIM-to-OFF capability to fixture-integrated sensors and controls.Dimming Interface Protection: The dimming circuit in an OPTOTRONIC linear driver have protection against AC line voltage (120-277Vac) in the event that the driver is mis-wiring during field installation. When a mis-wired driver is powered up, the driver will provide a visual signal that indicates a potential wiring error.Constant Lumen Maintenance: The Constant Lumen Maintenance feature of the OTi 85W helps to maintain the required lumen output of the fixture at a constant level throughout its lifetime. In general LED’s lumen output will depreciate over time and in order to maintain sufficient light level towards the end of lifetime, the LED’s are driven at high current initially and will result in more energy consumption. The constant lumen maintenance will give the flexibility to drive the LEDs at optimal drivReplacement for OSRAM: Replacement for OSRAM 57420 model LED driver. *2743W5 57420-Oti85/120-277/2A3/DIM-1 L
