Frequently Asked Questions

Can I use the LDH-25-250W for a constant current LED downlight?

Yes, this model provides 250 mA constant current output for LED loads operating within its 12-84V constant current range. It should be matched to constant current downlights, not constant voltage LED products.

Is the LDH-25-250W appropriate for small LED arrays or signage modules?

Yes, it can be used for small LED arrays or signage modules that are specified for 250 mA constant current drive. The load has to stay within the 12-84V constant current range, and the LED quantity depends on the forward voltage of each LED.

Can this driver help when the LED load needs more voltage than the source provides?

Yes, the LDH-25-250W is a step-up constant current driver with a 9-32VAC input and up to 84V output. That makes it relevant where the LED load voltage is above the available input range but still within the driver's constant current window.

What should I check for compatibility with the LDH-25-250W?

Check that the LED load is built for 250 mA constant current operation and that its operating voltage falls within the 12-84V constant current range. The final number of LEDs depends on the forward voltage of each LED, so there is no fixed LED count from the driver spec alone.

What environmental limits apply to the LDH-25-250W?

This model is specified for operation from -40°C to +70°C. No IP rating is listed in the provided specs, so environmental protection should be evaluated at the enclosure or system level.
