Frequently Asked Questions

Can I use the LDH-25-350 for LED downlights that run at 350 mA?

Yes, this is a 350 mA constant current LED driver with a 12-72V constant current output range and 25.2W power rating. It should be used with constant current LED loads rather than constant voltage products.

Is the LDH-25-350 suitable for signage modules or small LED arrays?

It can be used for signage modules or small LED arrays when the LEDs are designed for 350 mA constant current drive. The LED load must remain within the 12-72V constant current range, and the number of LEDs depends on each LED's forward voltage.

Can the LDH-25-350 be used in a system where the source is below the LED load voltage?

Yes, this is a step-up driver with a 9-32VAC input and up to 72V output. It is meant for constant current LED applications where the load voltage requirement is higher than the available input voltage.

How do I size an LED load for the LDH-25-350?

The load must be a 350 mA constant current load and must operate within the 12-72V constant current range. The number of LEDs is not fixed by the driver because it depends on the forward voltage of each LED in the array.

How does the LDH-25-350 compare with nearby LDH family options?

In the LDH-25 group, the 250 and 250W models are 250 mA, 12-84V, 21W; the 350 and 350W models are 350 mA, 12-72V, 25.2W; the 500 and 500W models are 500 mA, 12-50V, 25W; and the 700 and 700W models are 700 mA, 12-36V, 25.2W. Higher-output families listed here move to ratings such as 30.1W, 43W, 44.1W, 44.8W, 45.15W, 56W, 63W, 64.4W, and 64.75W with different current and voltage ranges.
