The most important features of OPTOTRONIC COMPACT constant current LED drivers

  • OPTOTRONIC Intelligent DALI window drivers are based on a digital platform and are fully programmable
    • LT2: Window driver with LEDset current setting
    • NFC: Window driver with NFC current setting

  • 3 ON/OFF driver families:
    • OPTOTRONIC FIT CS with DIP-switch current-setting drivers

OPTOTRONIC LED drivers for outdoor applications

  • Long life, low maintenance and high efficiency are very important for outdoor applications. OPTOTRONIC LED drivers for outdoor applications fulfil these expectations and use the advantages of LED-based light sources.
  • The high flexibility of these devices enables the optimal adaptation to required lighting conditions as well as the cost optimization of LED luminaire systems.
  • Significant energy savings as well as a reduction of CO₂ emissions can be achieved thanks to the integrated dimming functions (depending on the device family).
  • Because of the large operating window (voltage/current) of these LED drivers, a wide range of LED modules are supported.
  • OSRAM sets new standards with integrated overvoltage protection for protection class I and II luminaires.

Control interfaces/dimming possibilities

Stand-alone control

AstroDIM (1DIM, 2DIM and 4DIM types)

AstroDIM provides multi-stage night-time power reduction based on an internal timer referenced to the power ON/OFF time. There is no need for an external control infrastructure. The unit automatically performs a dimming profile based on the predefined scheduled reference to the midpoint, which is calculated based on the power ON/OFF times.

Presence-controlled (4DIM types)

In this dimming mode, the light output can be adjusted to the activity around each light point with an additional external sensor powered by the mains, regardless of the actual dimming level of the AstroDIM mode.

Group control

StepDIM (4DIM types)

The StepDIM (bi-power) mode allows switching between two output levels, the “normal” mode and the “reduced load” mode, by means of an additional switched phase. In the “reduced load” mode, the driver reduces the lighting level and therefore the energy consumption. The light levels can be pre-programmed flexibly.

MainsDIM (4DIM types)

This feature is mainly used in combination with magnetic ballasts for outdoor applications. The light output is reduced by lowering the mains voltage. The reduction of the mains voltage is applied by a controller in the distribution cabinet.

Network control

DALI (4DIM types)

In DALI mode, the driver can be integrated into a light management system such as the OSRAM Street Light Control system. The standardized DALI interface enables bi-directional communication between the driver and the light management system, which means that stepless dimming, status requests and addressing of each individual luminaire are possible.

0-10 V (DIM and 2DIM types)

With a 0-10 V interface, the driver can be integrated into a light management system such as the OSRAM Street Light Control system. This uni-directional interface allows adjusting the light output of the system.

Additional features

External temperature sensor

This feature allows the temperature protection of the LED module or the complete luminaire in hot ambient temperatures via an external sensor (e.g. NTC, negative temperature coefficient resistor). The derating can be modified via the Tuner4TRONIC software.

Tuning Factor

Within limits predefined by the luminaire manufacturer, this feature allows an adjustment of the amount of light in the field or in production. Thus, one luminaire can manage different lumen packages. If the feature is combined with LEDset2, other lumen packages can also be achieved which differ in terms of resistor coding.

High overvoltage protection

With the OSRAM-developed EQUI connection, these drivers (depending on the OPTOTRONIC family type) offer a high overvoltage protection up to 10 kV in common mode (6 kV in differential mode) for protection class I or II, protecting not only the LED driver, but also the connected module.
