Frequently Asked Questions
Can the NLDD-1400HW be used for constant-current LED downlights in compact fixtures?
Yes, if the LED downlight is specified for constant current operation and the total LED forward voltage stays within 6-46V. The driver is rated for 60W and uses a step-down constant current output, so it is not a replacement for a constant-voltage supply.
Is the NLDD-1400HW suitable for signage modules that need weather-resistant electronics?
It can be a fit where the LED load is constant current and environmental protection matters, because this model is rated IP67. It also operates across -40°C to +50°C, which supports use in installations exposed to outdoor or industrial temperature conditions.
Can I use this driver for a small high-power LED array?
Yes, if the array is a constant current LED load and its combined forward voltage remains within the 6-46V constant-current range. The total load also needs to stay within the 60W rating of the driver.
How do I size an LED load for the NLDD-1400HW?
Start with the LED load's total forward voltage and confirm it falls within the 6-46V constant-current output range. The number of LEDs depends on each LED's forward voltage, so there is no fixed LED count that applies to every design.
What are the main differences between the NLDD-1400HW and its series siblings?
This model shares the 60W rating with the full sibling group but uses 1.4mA output and a 46-6V constant-current range, the same as the 1400H. The 1200H and 1200HW are 1.2mA at 46-6V, while the 1050H/1050HW, 700H/700HW, 500H/500HW, and 350H/350HW use a 52-6V constant-current range with output currents of 1.05mA, 0.7mA, 0.5mA, and 0.35mA.
