Frequently Asked Questions
Can I use the LDH-45A-1050 for high-output LED downlights that need 1050mA constant current?
Yes, if the downlight is designed for 1050mA constant current operation and the total LED forward voltage is within the 12-43V CC range. This model provides up to 45.15W, which makes it suitable for higher-power constant current LED loads than the 25W LDH units.
Is the LDH-45A-1050 suitable for outdoor signage or exposed lighting modules?
It is rated IP67 waterproof, so it is better suited to wet or exposed conditions than non-IP-rated versions in the series. The driver still needs to match a constant current LED load of 1050mA with a combined forward voltage in the 12-43V range.
Can this driver power a larger small-form LED array than the LDH-25 series?
Yes, this model supports 45.15W at 1050mA with a 12-43V constant current range, while the LDH-25 models are lower-power units. It is intended for constant current LED arrays that need more output power and current than the smaller LDH-25 drivers provide.
How do I determine if my LED array is compatible with the LDH-45A-1050?
The array must be specified for 1050mA constant current operation, and the total LED forward voltage must stay within the 12-43V CC range. The number of LEDs depends on the forward voltage of each LED, so there is no single fixed LED count that applies to every load.
Is the LDH-45A-1050 rated for harsh environmental conditions?
Yes, it is rated IP67 waterproof and for operation from -40°C to +70°C. It also carries CE and EAC certifications and includes a 3 year warranty.
