Key Application Notes

• All OPTOTRONIC Programmable LED Drivers are factory programmed to a default level, which 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 NTC’s resistance change 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 driver’s output current 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.
