eldoLED *2743YN 50W Dimmable LED Driver, Programmable Outdoor (Osram

The OPTOTRONIC programmable dimmable family consists of highly efficient, constant current LED drivers for outdoor applications. One-click programming through the OPTOTRONIC Programmer allows OEMs to configure the output current with 1mA resolution. Also fully customizable by the OEM are the proprietary AstroDIM and LEDset features. AstroDIM is autonomous dimming for a night-time power reduction based on an internal timer that can be set for an entire year. The LEDset feature automatically sets the output current based on the module that is connected.

These drivers are available in dimming to 1% with built-in 0-10V dimming, enabling direct integration and operation with standard dimmers, sensors, as well as energy and light management systems.

DEXAL® enables bi-directional communications between the driver and the fixture-integrated component. It provides exact luminaire-specific data, including diagnostics, to light management systems.

• All OPTOTRONIC Programmable LED Drivers are factory programmed to a default level that can be adjusted to the desired settings.
• The current foldback accuracy is within +/-5% of the expected value. This value would also depend on the tolerance of the NTC component.
• Each driver in a luminaire requires a dedicated NTC device. Connecting a single NTC to multiple drivers can lead to inconsistent dimming and strobing effects.
• For UL SREC-certified drivers, Fixture Thermal Protection is turned OFF by default.
• To ensure that the protection is only triggered when there is a constant abnormality, there is a time delay of 1 min incorporated in the firmware. If the change in resistance of the NTC is persistent for this time, the driver confirms the abnormality and enters the protection mode
• Due to the above, this feature cannot be used to set the output current of the driver's using a potentiometer. In select LED drivers, designers can take advantage of the LEDset functionality. To learn more about this, please refer to the web resource.
