Frequently Asked Questions
Can I use the NLDD-350H to drive a low-current LED downlight module?
Yes, if the LED downlight is designed for constant current operation at 350mA. This is a 60W step-down constant current driver, so it fits LED loads that need regulated current rather than a constant voltage supply.
Is the NLDD-350H suitable for signage modules or small LED arrays?
It can be a fit for signage modules or small LED arrays when the LEDs are intended to run from a 350mA constant current source. Because it is a step-down driver with a 6-52VAC input and 52-6V constant current range, the LED load has to stay within that operating window.
Can this driver be used in compact lighting assemblies where space is limited?
The NLDD-350H is very compact at 32.1 × 20.5 × 12.5 mm and weighs 0.0156 kg, which helps in small integrated lighting products. It is still a 60W constant current driver, so the electrical match matters as much as the physical size.
How do I know if my LED load is compatible with the NLDD-350H?
This model is for constant current LED loads, not constant voltage LED products. Its constant current output range is 52-6V, and the number of LEDs it can run depends on the forward voltage of each LED in the load rather than on a fixed LED count.
How does the NLDD-350H compare with other NLDD H-series drivers?
Within this 60W series, the listed siblings are NLDD-350HW at 0.35mA with 52-6V, NLDD-500H and NLDD-500HW at 0.5mA with 52-6V, NLDD-700H and NLDD-700HW at 0.7mA with 52-6V, NLDD-1050H and NLDD-1050HW at 1.05mA with 52-6V, and NLDD-1200H, NLDD-1200HW, NLDD-1400H, and NLDD-1400HW with 46-6V at 1.2mA or 1.4mA. The NLDD-350H is the pin-style 350mA option in that family.
