FAQ

Can I use the LDH-65-1400 for a 1400mA LED downlight?

Yes, if the downlight is designed for constant current at 1400mA. The LED load must fall within the 12.5-46V CC range, and the driver is rated for 64.4W.

Is this a good match for small LED arrays that need more current than 1050mA?

It can be, because this model delivers 1400mA constant current with a 12.5-46V output range. That makes it better suited to small LED arrays designed around 1400mA rather than lower-current constant-current drivers.

Can the LDH-65-1400 power constant-current signage modules?

Yes, as long as the signage module is specified for constant current at 1400mA. Its total forward voltage must stay within 12.5-46V, and the overall load must remain within the 64.4W rating.

How do I size LEDs with this 1400mA driver?

Choose a constant-current LED load that requires 1400mA and has a combined forward voltage within 12.5-46V. The number of LEDs depends on the forward voltage of each LED, so compatibility is based on voltage range rather than a fixed count.

Is this driver suitable for exposed outdoor use?

No IP rating is listed for the LDH-65-1400, so it should not be assumed to be waterproof. It can operate from -40°C to +60°C with load derating per the derating curve, but weather exposure depends on using an appropriate enclosure.
