Frequently Asked Questions
Can I use the LDH-65-1750 for high-power LED downlights?
Yes, this driver can fit LED downlights that require a constant current output of 1750mA and operate within a 12-37V constant current range. Its 64.75W rating suits higher-power downlight assemblies, and the step-up design is intended for LED loads rather than constant voltage lighting products.
Is the LDH-65-1750 suitable for LED signage modules?
It can be used for signage modules only when the module is designed for constant current operation at 1750mA and the total LED load falls within the 12-37V CC output range. It is not the right choice for standard constant voltage sign modules that expect a fixed voltage supply.
Can this driver run a small LED array from a low-voltage source?
Yes, the LDH-65-1750 is a step-up constant current driver with a 9-32VAC input and a 12-37V CC output range, so it is intended for LED arrays that need current regulation rather than fixed voltage. It is best matched to arrays specified for 1750mA constant current operation.
How do I know if my LEDs are compatible with the LDH-65-1750?
Your LED load needs to be rated for constant current operation at 1750mA, and the total forward voltage of the LEDs must stay within the 12-37V CC output range. The number of LEDs depends on each LED's forward voltage, so there is no fixed LED count for this model.
What is the difference between the LDH-65-1750 and the other LDH-65 models?
Within the LDH-65 group, the sibling specs are: LDH-65-700 and LDH-65-700W at 700mA with a 12-80V CC range and 56W, LDH-65-1050 and LDH-65-1050W at 1050mA with a 12-60V CC range and 63W, LDH-65-1400 and LDH-65-1400W at 1400mA with a 12-46V CC range and 64.4W, and LDH-65-1750W at 1750mA with a 12-37V CC range and 64.75W. The LDH-65-1750 shares the same 1750mA, 12-37V, and 64.75W specs as the LDH-65-1750W, with the product difference shown as pin style versus wire style.
