Frequently Asked Questions
Can the LDH-45B-1050W run a 1050mA LED downlight?
Yes, if the downlight is built for constant current operation at 1050mA and its total LED forward voltage is within the 21-43V CC range. This is a constant current driver, not a constant voltage supply. Its maximum output power is 45.15W.
Is this a fit for 1050mA signage modules?
It is a fit when the signage module requires 1050mA constant current and the total forward voltage falls within 21-43V. Because this model regulates current rather than voltage, it should not be used for constant voltage signage products. The driver is rated up to 45.15W.
Can I use this driver for a compact LED array that needs boosted output voltage?
Yes, this step-up LED driver is designed for constant current output at 1050mA with a 21-43V CC range. It can support a compact LED array when the array's total forward voltage stays inside that range. The exact LED quantity depends on the forward voltage of each LED.
Is the LDH-45B-1050W suitable for outdoor lighting assemblies?
It has an IP67 waterproof rating, which makes it appropriate for wet and dusty environments where that level of ingress protection is required. The operating temperature range is -40°C to +70°C, supporting use across a wide temperature span. Overall fixture suitability still depends on the rest of the assembly.
What should I verify before pairing this driver with an LED load?
Check that the LED load is designed for 1050mA constant current operation and that its total forward voltage is within the 21-43V CC output range. The number of LEDs depends on the forward voltage of each LED, so there is no universal LED count. Loads that require constant voltage are not compatible with this model.
How does the LDH-45B-1050W compare with the other 1050mA LDH-45B options?
The LDH-45B-1050W shares the same 45.15W rating and 21-43V CC range as the LDH-45B-1050, while the LDH-45B-1050DA and LDH-45B-1050WDA use a narrower 36-43V CC range. All four are 1050mA constant current models with a 43V output rating. The W versions are wire style, and the non-W versions are pin style.
