FAQ

Can the LDH-65-1400W run a high-current LED downlight array?

Yes, if the downlight array is built for constant current at 1400mA. The total LED forward voltage must stay within the 12.5-46V CC range, and the driver is rated for 64.4W.

Is this driver suitable for small LED arrays that need 1400mA constant current?

Yes. The LDH-65-1400W provides 1400mA constant current over a 12.5-46V range, which fits small LED arrays designed for that current level. It should not be treated as a constant-voltage LED power supply.

Can I use this wire-style model for constant-current signage modules?

Yes, if the signage module is designed for constant current at 1400mA. The module's total forward voltage must be within 12.5-46V, and the total power draw must stay within 64.4W.

What determines whether my LED load is compatible with the LDH-65-1400W?

The LED load needs to be a constant-current load rated for 1400mA, with a combined forward voltage inside the 12.5-46V CC range. The number of LEDs varies with the forward voltage of each LED, so there is no single fixed LED quantity.

Can this driver be used where temperature swings are a concern?

Yes, it is rated for operation from -40°C to +60°C, with load derating per the derating curve. No IP rating is listed, so moisture and dust protection must come from the enclosure or finished fixture rather than the driver itself.
