FAQ
Can the LDH-65-700W be used for a 700mA LED downlight?
Yes, it is designed for constant current LED loads that need 700mA and fall within the 12.5-80V CC output range. With 56W output power, it fits downlight assemblies that require current-controlled operation instead of constant voltage input.
Will the LDH-65-700W work for LED channel letters or sign modules?
It can work when the sign modules are built as a 700mA constant current load and the combined LED forward voltage is within 12.5-80V. It should not be used in place of a constant voltage power supply for standard sign modules.
Is this driver appropriate for a small multi-LED array with a wide voltage requirement?
Yes, the 12.5-80V CC range gives this driver flexibility for 700mA constant current LED arrays with a broad total forward voltage requirement. That wider range is one of the main differences between this model and lower-voltage LDH variants.
What kind of LED load is compatible with the LDH-65-700W?
The LEDs must be intended for constant current operation at 700mA, and the total LED forward voltage must stay within the 12.5-80V CC output range. The number of LEDs depends on each LED's forward voltage, so the correct array size varies by LED type.
How is the LDH-65-700W different from the rest of the LDH-65 family?
Within the LDH-65 family, the sibling specs are: LDH-65-700 at 700mA with a 12.5-80V CC range and 56W, LDH-65-1050 and LDH-65-1050W at 1050mA with a 12.5-60V CC range and 63W, LDH-65-1400 and LDH-65-1400W at 1400mA with a 12.5-46V CC range and 64.4W, and LDH-65-1750 and LDH-65-1750W at 1750mA with a 12.5-37V CC range and 64.75W. The LDH-65-700W matches the LDH-65-700 electrically, with the listed distinction being wire style instead of pin style.
