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 I use the Mean Well NLDD-700HW for LED downlights?

Yes, this model can fit LED downlights that require a constant current driver at 700mA. It is a step-down LED driver with a constant current voltage range of 6 ~ 52VDC, so the downlight load needs to fall within that range. Its fully potted epoxy construction helps where extra environmental protection is needed.

Is the NLDD-700HW suitable for LED signage modules?

It can be suitable for LED signage modules if the modules are designed for constant current operation at 700mA rather than constant voltage. The supported constant current voltage range is 6 ~ 52VDC, and total load must stay within the 60W rating. Its fully potted epoxy construction also makes it a better fit for harsher conditions than non-sealed drivers.

Can this driver run a small LED array?

Yes, it is intended for constant current LED loads such as small LED arrays when the array requires 700mA constant current. The load voltage must stay within the 6 ~ 52VDC constant current range, and the total power must remain within 60W. It is not the right choice for LED products that expect constant voltage input.

Can I use the NLDD-700HW in outdoor or dusty environments?

This model is fully potted in epoxy (UL94-V0), which makes it appropriate for environments where moisture and dust resistance matter. Its operating temperature range is -40°C to +50°C, so the surrounding conditions need to stay within that window. Environmental suitability still depends on the rest of the system meeting the same conditions.

How do I know if my LEDs are compatible with the NLDD-700HW?

Your LEDs need to be designed for constant current operation at 700mA, not constant voltage operation. The driver supports a constant current output voltage range of 6 ~ 52VDC, and the number of LEDs depends on the forward voltage of each LED. The total load also needs to stay within the 60W rating.

What is the difference between the NLDD-700HW and other NLDD-H series models?

The main difference is output current. In the same series, the NLDD-350H and NLDD-350HW are 350mA with a 6 ~ 52VDC constant current range and 60W, the NLDD-500H and NLDD-500HW are 500mA with a 6 ~ 52VDC range and 60W, the NLDD-700H is 700mA with a 6 ~ 52VDC range and 60W, the NLDD-1050H and NLDD-1050HW are 1050mA with a 6 ~ 52VDC range and 60W, and the NLDD-1200H, NLDD-1200HW, NLDD-1400H, and NLDD-1400HW are 1200mA or 1400mA with a 6 ~ 46VDC range and 60W.
