Frequently Asked Questions
Can the NLDD-500HW be used for a constant current LED downlight module?
Yes, if the downlight module is designed for 500mA constant current operation. The NLDD-500HW is a 60W step-down constant current driver, so it is not intended for loads that expect fixed constant voltage output.
Is this driver suitable for LED signage modules that need moderate drive current?
It can be suitable for signage modules or small LED arrays built for 500mA constant current input. The LED load also has to stay within the driver's 52-6V constant current operating range.
Can the NLDD-500HW be used in outdoor or damp-location LED products?
Its IP67 rating supports use in more exposed environments, and the operating temperature range is -40°C to +50°C. That makes it practical for sealed LED products operating within those limits.
How do I check LED compatibility for the NLDD-500HW?
The key point is that this is a constant current driver, not a constant voltage supply. Its constant current range is 52-6V, and the number of LEDs depends on the forward voltage of each LED rather than on a single fixed count.
How does the NLDD-500HW compare with other wire-style NLDD models?
The listed wire-style siblings are NLDD-350HW at 0.35mA with 52-6V, NLDD-700HW at 0.7mA with 52-6V, NLDD-1050HW at 1.05mA with 52-6V, NLDD-1200HW at 1.2mA with 46-6V, and NLDD-1400HW at 1.4mA with 46-6V, all shown at 60W. The NLDD-500HW sits in the middle of that group as the 500mA wire-style model.
