Frequently Asked Questions
Can the XLC-40-H-S drive LED downlights with the output current configured by dip switch?
Yes, the XLC-40-H-S uses a dip switch to set the output current within the 0.6–1.4A adjustment range. This allows the drive current to be matched to different LED downlight loads at commissioning time. Once set, the constant current output maintains stable current to the LED load across the full 9–54V CC operating range.
Is the XLC-40-H-S appropriate for powering LED modules in retail signage or channel letter applications?
The XLC-40-H-S can drive LED signage modules whose cumulative forward voltage falls in the 9–54V CC range and total consumption stays within 40W. The dip switch current selection lets installers tune the output at installation to match the specific LED module's rated drive current. The number of LEDs per string depends on each LED's forward voltage.
Can the XLC-40-H-S be used for flicker-sensitive applications such as studio or broadcast lighting?
The XLC-40-H-S is specified as flicker-free, making it suitable where camera-visible flicker must be avoided. It delivers 40W at 1050mA constant current across a 9–54V CC range, and its Class II design with PFC meets the electrical quality requirements common in professional lighting environments.
What is the benefit of the strain-relief fitting on the XLC-40-H-S compared to the XLC-40-H model?
The XLC-40-H-S adds a factory-fitted strain-relief cable fitting to the base XLC-40-H specification, mechanically securing the output cable at the housing. This reduces stress on the cable connection from tension or movement during and after installation. Both models share the same 40W, 1050mA, 9–54V constant current electrical specifications.
What LED voltage range is the XLC-40-H-S compatible with?
The XLC-40-H-S has a CC output voltage range of 9–54V and operates as a constant current driver. LED arrays with series forward voltages summing between 9V and 54V are compatible at the selected drive current. The exact number of LEDs per string is not fixed — it depends on the forward voltage of the specific LEDs being used.
Is the XLC-40-H-S rated for installation inside an enclosed luminaire in a warm environment?
Yes, the XLC-40-H-S is designed for built-in installation inside a luminaire or protective enclosure. It operates from -25°C to +90°C, accommodating elevated temperatures inside enclosed downlight housings. It does not carry an IP rating, so it should not be directly exposed to moisture.
