Frequently Asked Questions
Can I set the drive current on the XLC-40-H-BN without opening the fixture after installation?
Yes. The XLC-40-H-BN uses NFC for current setting, allowing the output current to be programmed wirelessly through a luminaire housing using a compatible NFC programmer. This is particularly useful for in-situ adjustments on installed downlights or ceiling fixtures.
Is the XLC-40-H-BN appropriate for dimmable LED downlights in commercial offices?
Yes. It supports 3-in-1 dimming (0–10V, PWM, and resistance) and provides flicker-free constant current output at 1050mA. The NFC current-setting feature also allows output current to be adjusted between 0.6A and 1.4A without disassembling the fixture.
Can I use the XLC-40-H-BN in a recessed LED module array for museum or gallery lighting?
The driver is specified for built-in use and operates flicker-free at 1050mA with a 40W power envelope. It suits precision lighting applications where both stable current and dimming flexibility are needed. The 3-in-1 dimming input is compatible with widely used gallery lighting controllers.
How does NFC current setting differ from dip switch setting on XLC-40-H siblings?
Models ending in -N or -BN use NFC to set current wirelessly, while standard -B and non-suffixed models use a physical dip switch. Both cover the same 0.6–1.4A adjustment range. NFC is preferred when the driver is embedded inside a sealed luminaire where physical switch access is impractical.
What CC voltage range must my LED string match for the XLC-40-H-BN?
The constant current output operates within a voltage range of 9–54V. LED strings must be sized so their total forward voltage at the selected drive current falls within this window. The number of LEDs in the string depends on the forward voltage of each individual LED.
What is the operating temperature range of the XLC-40-H-BN?
The driver is rated from -25°C to +90°C. It is designed for built-in use, so it should be mounted inside a luminaire enclosure. Thermal performance should be verified to keep case temperature within the rated range, especially in high-ambient installations.
