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-700H drive a higher-current LED downlight module?

Yes, when the LED downlight is built for constant current operation at 700mA. This is a 60W step-down constant current driver, so it is intended for LED loads that require regulated current rather than constant voltage.

Is the NLDD-700H a fit for signage modules or dense small LED arrays?

It can be, provided the signage module or LED array is specified for 700mA constant current drive. The load also needs to stay inside the 52-6V constant current range of the driver.

Can this model be used where a small driver footprint matters?

Yes, the NLDD-700H measures 32.1 × 20.5 × 12.5 mm and weighs 0.0156 kg, so it can suit compact LED assemblies. It still delivers up to 60W, so both thermal design and electrical compatibility need to be considered in the final product.

How do I size an LED load for the NLDD-700H?

This driver should be matched to constant current LED loads, not constant voltage LED products. Its constant current output range is 52-6V, and the number of LEDs depends on the forward voltage of each LED in the array rather than on a fixed LED quantity.

Can the NLDD-700H operate in demanding environmental conditions?

The unit operates from -40°C to +50°C (refer to derating curve) and is fully encapsulated in epoxy (UL94-V0). It is designed for indoor or protected applications, as it does not carry an IP rating for outdoor exposure.
