Product identity

This pack contains ten Osram OPTOTRONIC 79471 programmable linear constant current LED power supplies. Each unit delivers up to 85 watts of total output power and is designed for professional lighting installations that require adjustable current and dimming control.

Build and connections

The ballasts support an output current range of 2000 to 2600 milliamps, programmable to suit the connected LED load, with an output voltage window of 20 to 55 volts. Dimming is handled through a standard 0-10V interface providing a 10 to 100 percent dimming range, while integrated LED thermal protection helps safeguard the light engines during operation.

Compatibility check

Verify that your LED modules operate within the 20 to 55 volt output range and can accept a programmable constant current between 2000 and 2600 milliamps. Confirm the mains supply is compatible with the 120 to 277 volt input rating and that your dimming controls use a 0-10V signal. These units are supplied as a case of ten and are not sold individually.

Questions about this item

What does the 0-10V dimming interface cap the output at?

The 0-10V dimming control adjusts the output current between 10% and 100% of the programmed level, spanning 2000-2600 mA.

What are the physical mounting requirements for this ballast?

The unit is a linear LT2 case designed for standard channel mounting within a luminaire; allow space for wiring access to the 120-277V input and 0-10V dimming leads.

How is the output current programmed during installation?

Use the Osram programming tool or compatible software to set the desired constant current between 2000 and 2600 mA before connecting the LED load; skipping this step leaves the driver at its default setting.
