Frequently Asked Questions
Can the XLC-40-H-SN power LED downlights with the output current programmed via NFC and cable strain relief included?
Yes, the XLC-40-H-SN combines NFC current setting with a built-in strain-relief fitting. You can program the drive current anywhere in the 0.6–1.4A range using a compatible NFC device, and the strain-relief fitting secures the output cable mechanically. This makes it convenient for enclosed downlight installations where the driver is not easily accessible after fitting.
Is the XLC-40-H-SN suitable for driving LED arrays in illuminated architectural or cove lighting?
The XLC-40-H-SN can power LED arrays for cove or architectural lighting where constant current drive is required. Its 40W output at 1050mA with a 9–54V CC range covers a broad range of LED configurations, and the NFC-adjustable current allows fine-tuning without opening or rewiring the fixture after installation.
Can the XLC-40-H-SN be used in studio or broadcast lighting where flicker must be avoided?
The XLC-40-H-SN is specified as flicker-free, making it suitable for studio or broadcast environments where camera-visible flicker is unacceptable. It operates at 1050mA constant current across a 9–54V CC range, and its Class II, PFC-compliant design meets the power quality requirements common in professional lighting infrastructure.
What is the difference between the XLC-40-H-N and the XLC-40-H-SN?
The XLC-40-H-N and XLC-40-H-SN are both 40W, 1050mA NFC current-programmable drivers with the same 9–54V CC range, input range, and certifications. The XLC-40-H-SN adds a strain-relief cable fitting to the housing, providing mechanical cable retention. Both share the 147.0 × 32.0 × 40.0 mm form factor.
What LED array voltage range does the XLC-40-H-SN support?
The XLC-40-H-SN operates as a constant current driver with a CC output voltage range of 9–54V. LED strings with series forward voltages summing between 9V and 54V are compatible at the selected output current. The exact number of LEDs per string depends on the individual forward voltage of your specific LEDs — always verify Vf before sizing the string.
Is the XLC-40-H-SN rated for built-in installation in enclosed luminaires?
Yes, the XLC-40-H-SN is designed for built-in installation inside a luminaire or protective enclosure. It operates from -25°C to +90°C, which covers the elevated ambient temperatures inside enclosed ceiling fixtures. It does not have an IP rating for moisture exposure and should be used in dry or sheltered environments.
