Frequently Asked Questions
Can I use the LDD-700LW for a lower-voltage 700mA LED downlight?
Yes, this model is suitable for 700mA constant current LED loads within a 2-32V output range. Its maximum output power is 22.4W, so it fits lower-voltage downlight engines and similar LED assemblies that stay within those limits. It is a constant current driver rather than a constant voltage supply.
Is the LDD-700LW a fit for small LED arrays with shorter series strings?
It is often a better fit where the LED array stays within a 2-32V constant current range instead of needing the higher output range of 45V or 52V models. The driver provides 700mA output and up to 22.4W. That makes it suitable for smaller arrays built around lower total forward voltage.
Can this driver be used for compact signage modules?
Yes, if the signage module string is designed for 700mA constant current operation and falls within 2-32V. Its compact dimensions of 22.6 × 9.9 × 8.9 mm also make it useful where space is limited. It should not be used for signage products that require constant voltage input.
Is the LDD-700LW suitable for outdoor or damp environments?
The driver is rated IP67 waterproof, so it is intended for applications needing sealed protection against dust and water ingress. The operating temperature range is -40°C to +85°C. That combination supports use in demanding indoor or outdoor equipment where the rest of the assembly is also properly protected.
How do I size an LED load for the LDD-700LW?
Choose LEDs that require 700mA constant current and make sure the total forward voltage stays within the 2-32V constant current range. The number of LEDs depends on each LED's forward voltage, so there is no universal LED count. If the LED product is specified for constant voltage, this is not the correct driver type.
