eldoLED | *274A1P Oti55W/120-277/2A0/DIM-1/J AUX | LED Driver | Replacement for 57358 Osram

- SYNCHRONIZE 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. - END-OF-LIFE INDICATOR: The END-OF-LIFE INDICATOR helps the end user to receive a signal from the fixture indicating that it has reached its programmed life-time. After the LED driver reaches the programmed life-time, whenever it is turned ON, it stays at Dim level (10%) for 10 minutes and reaches its appropriate level. - CONSTANT LUMEN MAINTENANCE: The CONSTANT LUMEN MAINTENANCE feature of the OTi25W helps to maintain the required lumen output of the fixture at a constant level throughout its lifetime. - 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
