FAQ

Can I use the LDH-65-1050 for a high-output LED downlight?

Yes, if the downlight is a constant-current design that requires 1050mA. The LED load needs to fall within the 12.5-60V CC range, and the driver is rated for 63W.

Is the LDH-65-1050 a fit for small LED arrays that need 1050mA?

Yes. This model provides constant current at 1050mA with a 12.5-60V output range, which makes it suitable for small LED arrays built around that drive current. It should not be used as a constant-voltage power supply.

Can this driver run constant-current signage modules?

Yes, when the signage module is specified for constant current at 1050mA. The total forward voltage of the LED load must stay within 12.5-60V, and the total load must remain within the 63W rating.

What should I check to confirm LED compatibility with this driver?

Check that the LED load is rated for constant current at 1050mA and that its combined forward voltage falls within 12.5-60V. The number of LEDs is not fixed, because it depends on the forward voltage of each LED in the array.

Is this model intended for exposed outdoor locations?

No IP rating is listed for the LDH-65-1050, so it should not be treated the same as a sealed waterproof driver. Its operating temperature range is -40°C to +60°C with load derating per the derating curve, but exposed wet or dusty use depends on the enclosure used around it.
