Frequently Asked Questions
Can I use the LDDS-250HWB with a 250mA dimmable LED downlight?
Yes, if the downlight is a constant-current load rated for 250mA and its LED voltage stays within the 45-2V CC range. This model is a 45W constant-current step-down driver, so it is not intended for constant-voltage downlights.
Is the LDDS-250HWB appropriate for dimmable signage modules?
It can be used with constant-current signage modules that require 250mA and operate within the 45-2V range. The IP67 construction also makes it suitable for harsher environments than open indoor-only electronics.
Can this model drive a small LED array that needs lower current?
Yes, if the array is designed for constant-current operation at 250mA and the total forward voltage fits within 45-2V. The number of LEDs will vary with the forward voltage of each LED, so there is no single fixed LED count.
How do I know if my LED load is compatible with the LDDS-250HWB?
The load needs to be a constant-current LED load, not a constant-voltage LED strip or module. This driver regulates 250mA across a 45-2V constant-current output range, and the final LED quantity depends on each LED's forward voltage.
What conditions is the LDDS-250HWB built to handle?
This driver is rated IP67 and has an operating temperature range of -40°C to +55°C. Those specs make it suitable for demanding indoor or outdoor environments when the LED load is also within the driver's electrical limits.
