OPTOTRONIC 55W Programmable Compact LED Driver
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.

Key Application Notes
- Dim-to-off and Soft Start are programmable (enable/disable) features. The default mode for both features is disabled for out-of-the-box products. If these features are required, they must be enabled in the programming software.
- If LED Thermal Protection feature is used, an NTC thermistor must be connected to the driver.
Key Features & Benefits
- 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 abnormal and enters the protection mode
- Due to the above, this feature cannot be used to set the output current on 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.
