OPTOTRONIC 30W Programmable Linear LED Driver

The OPTOTRONIC programmable dimmable family consists of highly efficient, linear, constant current LED drivers. One-click programming through the OPTOTRONIC programmer allows OEMs to configure the output current with a 1mA resolution. Also fully customizable by customers are the end-of-life indicator, LED thermal protection, and constant lumen maintenance features. The OPTOTRONIC programmer does not require the driver to be powered up or connected to AC line voltage while programming. The power supplies are available with a built-in 0-10V dimming protocol with models available in authentic  1% to 10%. The auxiliary output has the capability to power various sensors.

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 the LED Thermal Protection feature is used, an NTC thermistor must be connected to the driver.
