Frequently Asked Questions
Can I use the NLDD-1200H for LED downlights that need constant current?
Yes, this model is intended for constant current LED loads, including LED downlights, as long as the load operates within the 6-46V constant-current range. It is a 60W step-down driver, so it should not be used in place of a constant-voltage supply.
Is the NLDD-1200H a good fit for signage modules with a DC source already in the system?
It can fit signage modules that use constant current LEDs when the available input is within 6-46VAC and the LED load stays within the 6-46V constant-current range. Since it is a step-down constant current driver, the application has to match both the input range and the LED load requirements.
Can the NLDD-1200H be used for small constant-current LED arrays?
Yes, for small LED arrays that are specified for constant current rather than constant voltage. The driver supports up to 60W, and the array's combined forward voltage must stay within the 6-46V constant-current output window.
What should I check before pairing LEDs with the NLDD-1200H?
Check that the LED load is meant for constant current operation and that its total forward voltage falls within 6-46V during constant current operation. The number of LEDs depends on the forward voltage of each LED, so there is no single fixed LED quantity for this driver.
What is the difference between the NLDD-1200H and the other NLDD H-series versions?
All listed siblings are 60W models, but they differ by output current and constant-current voltage range. The 350H/350HW are 0.35mA at 52-6V, 500H/500HW are 0.5mA at 52-6V, 700H/700HW are 0.7mA at 52-6V, 1050H/1050HW are 1.05mA at 52-6V, 1200H/1200HW are 1.2mA at 46-6V, and 1400H/1400HW are 1.4mA at 46-6V.
