Frequently Asked Questions
Can I use the LDD-600HW for a 600mA LED downlight?
Yes, this model is a constant current LED driver with a 600mA output. It is intended for LED loads that operate within its 2-52V constant current range and up to 31.2W. The LED string voltage still needs to stay inside that 2-52V range.
Is the LDD-600HW suitable for signage LED modules that need constant current?
It can be used for signage modules when the module string is designed for constant current operation at 600mA. The available constant current output range is 2-52V with a maximum power of 31.2W. It is not a constant voltage driver, so it should not be chosen for LED modules that expect a fixed constant voltage supply.
Can this driver run a small LED array in a compact enclosure?
This model is built for compact installations, with a body size of 31.8 × 20.3 × 12.2 mm and a weight of 0.02 kg. It provides 600mA constant current with up to 52V output and 31.2W. That makes it suitable for small LED arrays that match those electrical limits.
Will the LDD-600HW work in outdoor or wet locations?
The unit is rated IP67, so it is designed for waterproof use where that level of ingress protection is required. Its operating temperature range is -40°C to +85°C, which also supports demanding ambient conditions. Final suitability still depends on the rest of the fixture or enclosure meeting the same environmental standard.
How do I know if my LEDs are compatible with the LDD-600HW?
Check that your LEDs require constant current at 600mA and that the total forward voltage falls within the 2-52V constant current range. The number of LEDs cannot be stated as a fixed count because it depends on each LED's forward voltage. If your LEDs need constant voltage instead of constant current, this is not the right driver type.
