OPTOTRONIC Constant current LED power supplies with 3DIM/DALI

OPTOTRONIC is the best DC power supply for LED lighting. By using standard IP 54 waterproof perfectly suitable for both outdoor use. The power supply can operate in a variable environment with high tolerances For the ambient temperature range from +55 C° to -30 C°. Ideal for class I and II luminaires.

3DIM / DALI adjustment gives you the ability to set different modes and levels of light output.

  • Features & Benefits

  • Wide output power range: up to 150 W
  • High overvoltage protection: up to 4/6 kV (L-N), 4/6 kV (L / N-PE)
  • Ability to set different modes and levels of control of the luminous flux
  • Stand-alone dimming function enables operation in existing installations
  • 3DIM functionality (StepDIM/AstroDIM/DALI)
  • Current output range: 75…700 mA
  • Flexible current setting
  • Constant lumen function
  • Overtemperature protection via external NTC (3DIMLT+ version only)

Up to 85000 h lifetime

By using top-quality OSRAM components, the life span of the power supply is estimated at over 9 years and 7 months of continuous operation. With standard usage it is over 19 years !

High temperature resistance

The durable casing of the power supply allows you to operate at extreme temperatures, resulting in minimal malfunction and long service life. The power supply is additionally protected by NTC, protecting the components from overheating during operation

High surge&shock protection

The EQUI pin is connected to the LED module heat sink to improve the shock resistance of the system. On the other hand, if the load input voltage exceeds the output voltage range of the controller, it automatically reduces the output power. Current holding the output voltage at the maximum permitted output voltage.
