Test conditions and notes4
  1. 1.All parameters are specified at normal input(24VDC), rated load, 25℃ 70% RH ambient.
  2. 2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1uf capacitor.
  3. 3.The output of LDB-L should not be connected to the input of the same unit or output from other sources.
  4. 4. If input voltage is 36V then the output voltage operating range had better <38V.

FAQ

Can I use the LDB-600L for a higher-current LED downlight?

Yes, this model provides 600mA constant current output, which fits LED downlights designed for 600mA drive current. The LED load must also stay within the 2-30V CC range, and the usable output voltage depends on input (up to 18V at 9V input, 24V at 12V, 30V at 16V).

Is the LDB-600L suitable for brighter signage modules or small LED arrays?

It can be used where the LED module or array is designed for 600mA constant current operation. Because the unit is constant current rather than constant voltage, it should be paired with LEDs specified for 600mA and a total forward voltage within 2-30V.

Can this driver support compact high-output LED arrays?

Yes, that is a reasonable application if the array requires 600mA and its forward voltage stays within the 2-30V output range. The buck-boost design also helps when the available input is within the 9-28VDC range.

How do I verify whether my LEDs are compatible with the LDB-600L?

Check that the LEDs are intended for 600mA constant current drive and that the string voltage falls within the 2-30V CC range. The number of LEDs depends on each LED's forward voltage, so there is no single fixed LED quantity for this model.

Can the LDB-600L handle outdoor or industrial conditions?

It is fully encapsulated with an IP67 rating, so it is built for applications that need strong protection against dust and water. The operating temperature range of -40°C to +70°C (refer to the derating curve) also supports use in demanding environments.
