Output current, LED Color, Wattage LED Driver

rgovande26

Hi

I am new to this group.

LED driver is new for me and I am learning about it now!

I recently started working on 8' LED tube light. It uses HOSSONI LED Driver (Ballast) SDC96CS200V48DL1A. I believe this is a Constant Current Driver.

t has following:

  • Input voltage measured is 120Vac
  • Output: 36-48Vdc, Actual No-load voltage: 55Vdc
  • 3-wires are connected to the LED lights
  • 3 position switch to select the color 5000-4000-3500K
  • Aux Output: 0-10Vdc (Not used)
  • 0-10Vdc for Dimmer So, a non-dimmable LED Driver should work.

Questions:

  1. A 3 position switch is used to set the color. Does this switch actually changes output currents to 1150mA, 1500mA, or 2000mA?
  2. Does Higher the output current mean higher K value?
  3. There is another switch for Wattage setting; 90-68-48W. What's the meaning of this? Is this the power wattage available or applied to the LED light?
  4. Does the change in output current changes above wattage (90-68-48W)?

Please let me know if more information is required from my side.

Thanks

    LEDs don't change color with power level, LED systems change color by having multiple LEDs where each LED may be a different color and varying the current in different colored LEDs.

    Questions

    1. A 3 position switch is used to set the color. Does this switch actually changes output currents to 1150mA, 1500mA, or 2000mA?

    No. The switch changes the LEDs driven to be either just the daylight colour, warm white colour or both to give you the three colour temperatures.

    2. Does Higher the output current mean higher K value?

    No. A higher output current pushes the LEDs harder and creates a higher brightness, but at the cost of heat and lifetime. A slight shift in spectrum does occur in white LEDs, but it's not a fixed relationship with CCT

    3. There is another switch for Wattage setting; 90-68-48W. What's the meaning of this? Is this the power wattage available or applied to the LED light?

    This is just selecting a different drive current to allow you to adjust the output.

    4. Does the change in output current changes above wattage (90-68-48W)?

    Yes.
