Test conditions and notes7

1.All parameters are specified at normal input(48VDC), rated load, 25℃ 70% RH ambient.
2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μf capacitor.
3.Test condition: 48VDC input.
4.Output voltage will always step down by 4 volts from input DC voltage.
5.The output of NLDD-H should not be connected to the input of the same unit or output from other sources.
6.The power supply is regarded as a part of the components in the system, and the final EMI test needs to be tested with the final device. If an additional EMI filter circuit is required to meet the electromagnetic compatibility requirements, please refer to the EMC test report for details.

FAQ

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?

The datasheet does not specify an IP rating, so it is not rated for outdoor or damp locations. The operating temperature range is -40°C to +50°C. It is fully potted and suitable 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 350mA with 6-52V, NLDD-700HW at 700mA with 6-52V, NLDD-1050HW at 1050mA with 6-52V, NLDD-1200HW at 1200mA with 6-46V, and NLDD-1400HW at 1400mA with 6-46V, all shown at 60W. The NLDD-500HW sits in the middle of that group as the 500mA wire-style model.
