Frequently Asked Questions
Can I use the LDD-600H for a 600mA LED downlight engine?
Yes, this driver is intended for constant current LED loads at 600mA. It supports a 2-52V constant current range with up to 31.2W, which makes it suitable for higher-power downlight modules than the 350mA versions.
Is the LDD-600H suitable for brighter signage modules or small LED arrays?
It can be a fit for signage modules and small LED arrays that are designed for 600mA constant current operation. The LED load must stay within the 2-52V range and within the 31.2W rating, and it is not a constant voltage driver.
Can this driver support a custom LED array with more headroom than a 350mA model?
Yes, the higher 600mA output current and 31.2W rating provide more output capacity than a 350mA model. It is still a constant current device, so the LED array must be specified for 600mA and remain within the 2-52V operating window.
How do I know whether my LED string is compatible with the LDD-600H?
Your LED load must require 600mA constant current, and its total forward voltage must fit within the 2-52V constant current range. The number of LEDs depends on each LED's forward voltage, so there is no single fixed LED count for this driver.
Can the LDD-600H be used in outdoor or high-variation temperature conditions?
Yes, it has an IP67 waterproof rating and an operating temperature range of -40°C to +85°C. That makes it suitable for protected LED systems exposed to dust, water, and wide ambient temperature changes.
How does the LDD-600H compare with other 600mA LDD drivers?
In the 600mA group, LDD-600H, LDD-600HS, and LDD-600HW are 31.2W with a 2-52V constant current range, LDD-600L and LDD-600LW are 19.2W with a 2-32V range, and LDD-600LS is 16.8W with a 2-28V range. The main differences are the available output voltage range, power level, and package style.
