SKU CH-DA07-YWCJ3

Programmable linear LED power supply delivering 85 W with 0-10 V dimming from 10 to 100 per cent and thermal protection

  • Programmable constant-current output matches LED load precisely
  • 85 watt total power drives high-output linear fixtures
  • 0-10V dimming from 10 to 100 percent range
  • LED thermal protection prevents overheating damage
  • Universal 120-277V input suits commercial installations

Programmable Linear LED Power Supply

The Osram Optotronic OTi85/120-277/2A6 DIM LT2 L is a programmable constant-current driver built for linear LED installations. It delivers 85 watt total output power and accepts a 120-277V input range for commercial and architectural lighting projects.

85 watt output with 2000-2600 mA range

The driver provides an adjustable output current from 2000 to 2600 mA and operates across a 20-55V output voltage window. It comfortably handles medium-power linear arrays but runs out of headroom for high-current or high-voltage LED strings beyond these limits.

0-10V dimming from 10 to 100 percent

Dimming control uses a standard 0-10V interface with a 10-100% dimming range and includes LED thermal protection. The protocol does not support dim-to-off or digital addressable control, so it cannot integrate with DALI or DMX systems without additional converters.

Questions about this item

Will the 79471 ballast power my existing LED modules that run at 2000-2600 mA and 20-55V?

Yes, the programmable constant-current output covers 2000-2600 mA across a 20-55V window, matching modules within that range.

How can I verify the 0-10V dimming is functioning correctly after installation?

Apply a 0-10V control signal; the output should scale smoothly from 10% to 100% of the programmed current.

Does the 79471 package include the programming tool or cable needed to set the output current?

The supplied unit is the power supply only; a separate programming interface must be obtained to configure the 2000-2600 mA setting.
