Frequently Asked Questions
Can I use the LDD-700H for a 700mA LED downlight?
Yes, this driver is designed for constant current operation at 700mA. It supports LED loads within a 2-52V constant current range and up to 36.4W. That makes it a fit for downlight designs that are specified for 700mA constant current.
Is the LDD-700H a good choice for small high-power LED arrays?
It can be used for small LED arrays when the array is intended to run at 700mA constant current. The driver supports up to 52V output and 36.4W, so the total LED forward voltage must remain within that window. This is a constant current model, not a constant voltage supply.
Can the LDD-700H be used for LED signage modules?
Yes, if the signage module string is designed for 700mA constant current operation. The driver provides a 2-52V constant current range and up to 36.4W, which suits many custom module strings and compact light engines. It should not be used in place of a constant voltage driver for modules that expect fixed-voltage input.
Is this driver suitable for harsh temperature conditions?
The rated operating temperature range is -40°C to +85°C. That gives it a wide environmental operating window for demanding indoor or protected outdoor equipment. The product is also rated IP67 waterproof.
How do I match LED strings to the LDD-700H?
Your LED load needs to be specified for 700mA constant current, and the total forward voltage must stay within the 2-52V constant current range. The exact number of LEDs depends on each LED's forward voltage, so there is no single fixed LED count. If the load requires constant voltage, choose a constant voltage driver instead.
