Frequently Asked Questions
Can I use the LDH-45B-1050 for a 1050mA LED downlight module?
Yes, if the downlight is designed for constant current operation at 1050mA and its total LED forward voltage falls within the 21-43V constant current range. This driver is not for constant voltage LED products. Its 45.15W rating also needs to match the load requirement.
Is this driver suitable for signage modules that need constant current instead of constant voltage?
It can be suitable for signage modules that are specified for 1050mA constant current input and operate within the 21-43V CC output range. It should not be used as a constant voltage power supply. The driver is rated up to 45.15W.
Can this power a small LED array in a step-up design?
Yes, this is a step-up constant current LED driver with a 1050mA output and a 21-43V CC range. That makes it appropriate for a small LED array when the array is built for constant current operation and the combined forward voltage stays within that range. The exact number of LEDs depends on each LED's forward voltage.
Is the LDH-45B-1050 a good fit for outdoor or damp-location LED lighting?
It is built with an IP67 waterproof rating, so it is suited to wet and dusty environments where that protection level is required. The operating temperature range is -40°C to +70°C, which supports use in both very cold and hot conditions. Final suitability still depends on the rest of the fixture meeting the same environmental demands.
How do I know if my LED load is compatible with this driver?
The LED load must be a constant current load rated for 1050mA, and the driver's CC output range is 21-43V. The number of LEDs it can run depends on the forward voltage of each LED, not on a fixed LED count. If the load needs constant voltage instead of constant current, this model is not the right match.
What is the difference between the LDH-45B-1050 and the other 1050mA LDH-45B versions?
Within the 1050mA LDH-45B group, the LDH-45B-1050 and LDH-45B-1050W are both 45.15W models with a 21-43V CC range, while the LDH-45B-1050DA and LDH-45B-1050WDA are 45.15W models with a narrower 36-43V CC range. The non-W versions are pin style, and the W versions are wire style. All four are rated for 43V output and 1050mA constant current operation.
