Frequently Asked Questions
Can I use the LDD-700H-WDA for a 700mA LED downlight engine?
Yes, this is a constant current step-down driver with a 700mA output. It supports LED loads across a 3-45V constant current range and up to 31.5W. That makes it suitable for downlight engines designed around 700mA constant current within that voltage range.
Is the LDD-700H-WDA suitable for compact signage light engines?
It can be used for compact signage light engines when the LED load requires 700mA constant current. The driver's output window is 3-45V with a maximum power of 31.5W. Loads designed for constant voltage should use a constant voltage driver instead.
Can this model power a small LED array with a lower input range?
Yes, this version is specified with a 6-50VAC input range, which is lower than the 9-56VAC range used by some other LDD models in the data provided. On the output side, it delivers 700mA constant current across 3-45V and up to 31.5W. It is suited to small LED arrays that stay inside those output limits.
Can the LDD-700H-WDA be used in wet or outdoor equipment?
The driver carries an IP67 waterproof rating, so it is intended for applications needing that level of ingress protection. Its operating temperature range is -40°C to +85°C, which supports demanding environmental conditions. The complete assembly still needs the rest of the system to be designed for the same environment.
How do I check LED compatibility with the LDD-700H-WDA?
Use it with LEDs that are designed for 700mA constant current and whose total forward voltage falls within the 3-45V constant current range. The number of LEDs will vary because it depends on each LED's forward voltage. This driver regulates current, so it is not intended for constant voltage LED loads.
