Frequently Asked Questions
Can I use the NLDD-1050HW for a constant-current LED downlight?
Yes, if the downlight is designed for a constant current driver and the LED load stays within the 6-52V constant-current output range. This model is a 60W step-down constant current driver, so it is not intended for constant-voltage LED products.
Is the NLDD-1050HW suitable for signage modules or small LED arrays?
It can be used for signage modules or small LED arrays when the LEDs are driven at constant current and the combined forward voltage falls within 6-52V. The output is constant current, not constant voltage, and the total load must remain within 60W.
Can this driver run a compact LED array in a sealed or exposed location?
The NLDD-1050HW has an IP67 rating, so it is built for dust-tight and water-resistant use around harsher environments than open indoor-only electronics. It also supports operation from -40°C to +50°C, which helps in installations exposed to wide temperature swings.
How do I know if my LED load is compatible with the NLDD-1050HW?
Your LED load needs to be a constant current load that operates within the 6-52V constant-current output range of this driver. The number of LEDs depends on the forward voltage of each LED, so compatibility is determined by total forward voltage rather than a fixed LED count.
How does the NLDD-1050HW compare with other NLDD H-series models?
Within this 60W series, the 350H and 350HW are 0.35mA with a 52-6V CC range, the 500H and 500HW are 0.5mA with a 52-6V CC range, the 700H and 700HW are 0.7mA with a 52-6V CC range, and the 1050H and 1050HW are 1.05mA with a 52-6V CC range. The 1200H and 1200HW are 1.2mA with a 46-6V CC range, while the 1400H and 1400HW are 1.4mA with a 46-6V CC range.
