Frequently Asked Questions
Can I use the LDH-45A-1050DA for a 1050mA LED downlight array?
Yes, if the downlight array is designed for constant current operation at 1050mA and its total forward voltage stays within the 24-43V constant current range. This is a constant current step-up driver, so it is intended for LED loads rather than constant voltage LED tape or strips.
Is the LDH-45A-1050DA suitable for powering signage LED modules?
It can be suitable for signage modules only when the modules are constant current types rated for 1050mA and the total LED forward voltage falls inside the 24-43V CC range. It is not the right match for constant voltage signage modules that expect a fixed voltage supply.
Can this driver run a small high-power LED array in an enclosed outdoor fixture?
Yes, it is built for demanding environments with an IP67 waterproof rating and an operating temperature range of -40°C to +70°C. The LED array still needs to be a 1050mA constant current load that operates within the 24-43V output range and 45.15W power limit.
How do I know if my LED load is compatible with the LDH-45A-1050DA?
Match the load to 1050mA constant current output and make sure the combined LED forward voltage is within 24-43V. The number of LEDs depends on each LED's forward voltage, so compatibility is based on total forward voltage rather than a fixed LED count.
How does the LDH-45A-1050DA compare with other 1050mA LDH series models?
Within the 1050 output-current group, LDH-45A-1050 and LDH-45A-1050W are 45.15W models with a 12-43V CC range, while LDH-45A-1050DA and LDH-45A-1050WDA are 45.15W models with a 24-43V CC range. LDH-45B-1050 and LDH-45B-1050W are 45.15W with a 21-43V CC range, LDH-45B-1050DA and LDH-45B-1050WDA are 45.15W with a 36-43V CC range, and LDH-65-1050 and LDH-65-1050W increase to 63W with a 12-60V CC range.
