Frequently Asked Questions
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 52-6V, so the downlight load needs to fall within that range. Its IP67 rating also 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 52-6V, and total load must stay within the 60W rating. Its IP67 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 52-6V 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 rated IP67, which makes it appropriate for environments where water 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 52-6V, 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 0.35mA with a 52-6V constant current range and 60W, the NLDD-500H and NLDD-500HW are 0.5mA with a 52-6V range and 60W, the NLDD-700H is 0.7mA with a 52-6V range and 60W, the NLDD-1050H and NLDD-1050HW are 1.05mA with a 52-6V range and 60W, and the NLDD-1200H, NLDD-1200HW, NLDD-1400H, and NLDD-1400HW are 1.2mA or 1.4mA with a 46-6V range and 60W.
