Frequently Asked Questions
Can I use the NLDD-1400H for high-current LED downlights?
Yes, when the downlight is designed for constant current operation and its LED load stays inside the 6-46V constant-current range. This model is rated at 60W and is intended for constant current applications rather than constant-voltage lighting products.
Is the NLDD-1400H suitable for small LED arrays that need a step-down driver?
It can be suitable for small constant current LED arrays when the source is within 6-46VAC and the LED load remains within the 6-46V constant-current range. Because it is a step-down design, the system input also needs to align with that operating window.
Can this model be used for rugged signage or enclosed LED modules?
Yes, the NLDD-1400H is rated IP67 and operates from -40°C to +50°C, which supports use in more demanding environmental conditions. It is still important that the LED module itself is a constant current load and fits within the driver's 60W and 6-46V limits.
What makes an LED load compatible with the NLDD-1400H?
The LED load must be intended for constant current operation and its total forward voltage must fall within the 6-46V constant-current output range. The number of LEDs depends on the forward voltage of each LED, so compatibility is based on the full load voltage rather than a specific LED quantity.
How does the NLDD-1400H compare with the other H and HW versions?
All listed siblings are 60W models, but current and constant-current range vary. The 1400H and 1400HW are 1.4mA with a 46-6V CC range, the 1200H and 1200HW are 1.2mA with a 46-6V CC range, and the 1050H/1050HW, 700H/700HW, 500H/500HW, and 350H/350HW use a 52-6V CC range at 1.05mA, 0.7mA, 0.5mA, and 0.35mA.
