Frequently Asked Questions
Can I use the LDH-45B-700WDA for a 700mA LED downlight?
Yes, if the downlight is designed for constant current at 700mA rather than constant voltage. The LED load also needs a total forward voltage within the 36-64V constant-current range, and the driver is rated for 44.8W.
Is this driver suitable for small LED arrays in a step-up design?
Yes. This is a constant-current step-up LED driver with a 700mA output and a 36-64V CC output range, so it fits small LED arrays that need 700mA and a higher LED voltage than the source can provide directly. The load still needs to stay within the 44.8W rating.
Can I use this for LED signage modules?
It can work for signage modules only when the module is a constant-current 700mA load. Many signage products are constant-voltage, so this model should only be used when the module's forward voltage falls within 36-64V and the system is specified for constant current.
How do I know if this driver is compatible with my LED load?
Match the driver to a constant-current LED load that requires 700mA. The connected LEDs must present a total forward voltage within the 36-64V CC range, and the actual number of LEDs depends on the forward voltage of each LED rather than a fixed LED count.
Can this driver be used in outdoor or harsh environments?
Yes. The LDH-45B-700WDA is rated IP67 and has an operating temperature range of -40°C to +70°C, so it is better suited to wet or demanding environments than non-sealed versions. Environmental suitability still depends on the rest of the fixture meeting the same level of protection.
